The 70% ethanol extract from Adenophora triphylla showed a strong antioxidant effect and reduced cytotoxicity of $H_2O_2$ in SK-N-SH cells. The chloroform fraction from A. triphylla extract (AT-CH) among the six fractions showed strong DPPH radical and intracellular reactive oxygen species (ROS) scavenger effects and the highest protective effect against $H_2O_2$-induced SK-N-SH cell death. Bioactivity compounds were purified from AT-CH, and the chemical structures of the compounds were determined as ${\beta}$-sitosterol and daucosterol on the basis of $^1H-NMR$, $^{13}C-NMR$, and EI mass spectra. ${\beta}$-Sitosterol and daucosterol also had protective effects against oxidative stress in SK-N-SH cells. Phospho-p38 MAPK levels were elevated by $H_2O_2$ but were inhibited by treatment with AT-CH and phytosterols (${\beta}$-sitosterol and daucosterol) isolated from AT-CH. These results suggest that AT-CH has brain neuroprotective effects against oxidative stress ($H_2O_2$) by inhibiting activation of p38 pathways and scavenging intracellular ROS.

This study was carried out to investigate the mutagenic, antimutagenic, cytotoxicity and antitumor effects of Adenophora triphylla (AT). AT was extracted with 70% ethanol and then further fractionated to hexane, chloroform, ethyl acetate, butanol and water. Antimutagenic, cytotoxicity and antitumor effects of AT extracts were measured by using Ames test, SRB method, and the tumor growth inhibition test. AT extracts did not show any mutagenicity in the Ames test; however, 70% ethanol extracts and its fractions had strong antimutagenic effects against mutation induced by N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) and 4-nitroquinoline-1-oxide (4NQO). The ethyl acetate fraction of AT (200 ${\mu}g$/plate) showed approximately 66.5% inhibitory effect on the mutagenesis induced by 4NQO against TA98 strain, whereas 83.3% and 75.1% inhibitions were observed on the mutagenesis induced by MNNG and 4NQO against TA100 strain. In anticancer effects, the cytotoxicity of AT extract and its fractions against cancer cell lines including human cervical adenocarcinoma (HeLa), human hepatocellular carcinoma (Hep3B), human breast adenocarcinoma (MCF-7), human gastric carcinoma (AGS), human lung carcinoma (A549) and transformed primary human embryo kidney (293) were investigated. The treatment of 1 mg/mL AT ethyl acetate faction had the highest cytotoxicity of 79.9%, 74.9%, 66.0%, 71.0% and 74.3% against HeLa, Hep3B, MCF-7, AGS and A549 cells, respectively. In contrast, the extract and its fractions showed only $3{\sim}36%$ cytotoxicity for a normal human kidney cell line (293). In vivo anti-cancer effect of Adenophora triphylla extract was tested using Balb/c mice transplanted sarcoma-180 cells. Adenophora triphylla ethyl acetate fraction showed the highest inhibition rate of 37.2% at the 50 mg/kg concentration.

The anti-cancer effects of Astragalus membranaceus (AM) and Adenophora triphylla var. japonica (AT) have been described. Each of their effects mainly focused on the immunopotentiating and apoptosis inducing-ability in several cancer cell lines. Although the combination of AM and AT is occasionally used in Chinese medicine to treat lung cancers, their synergistic effect has not been proved yet. This study was designed to verify whether AM combined with AT exhibits a synergistic anti-cancer effect in H1299 human lung carcinoma cells. The ethanol extracts of AM (EAM) and AT (EAT) showed only slight cytotoxicity in H1299 cells when treated alone. However, the combination of EAM and EAT markedly suppressed the cell growth measured by MTT assay and trypan blue counting assay. In addition, co-treatment of EAM with EAT significantly reduced the colony-forming ability compared with single treatment of EAM or EAT in H1299 cells. We demonstrated that the synergistic effect of AM and AT was related with apoptosis induction proved by an accumulation of chromatin condensation, annexin V-positive cells, sub-G1 phase population, and cleaved-PARP expression, which were not observed by single treatment of EAM or EAT. In conclusion, the combination of EAM and EAT exhibited superior anti-cancer activity in H1299 cells than single treatment of EAM or EAT. We suggest that EAM combined with EAT might be a novel therapeutic option for lung cancer patients, and provide a reference for the development of more effective combination of Chinese herbs to treat lung cancer.

The hepatoprotective effects of water extracts composed of Adenophora triphylla var japonica Hara (ATJH) on acetaminophen (APAP)-induced hepatotoxicity were investigated in vivo and in vivo. The effects of ATJH on liver toxicity induced by APAP were assessed by blood biochemical and histopathological analyses. APAP treatment (350 mg/kg) caused severe liver injury in mice as indicated by their significantly elevated plasma aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels. Pretreatment with ATJH for 3 or 7 days attenuated the increases in ALT and AST when challenged with APAP. The reductions in viability caused by high dose of APAP (450 mg/kg) in vivo were reversed by pretreatment with ATJH. These protective effects of ATJH against APAP-induced toxicity were consistent with the results from the histopathological examinations. We next examined the effects of ATJH on the gene expression of glutathione S-transferases (GSTs) that detoxify the metabolic intermediates of APAP in H4IIE cells. The hepatic GST protein levels [$\alpha$ class (GSTA2, GSTA3/5)] were significantly elevated in a dose-dependent manner by ATJH treatment. In summary, ATJH is effective at protecting against APAP-induced hepatotoxicity by GST induction, implying that ATJH should be considered a potential chemopreventive agent.

The levels of minerals, amino acids, fatty acids and sugars and antioxidant capacity of Adenophora triphylla (AT) root were investigated. The moisture, crude protein, crude lipid, crude ash and carbohydrate contents of the AT root were $3.4{\pm}0.3,\;9.4{\pm}0.1,\;1.6{\pm}0.1,\;3.7{\pm}0.2$, and $81.9{\pm}0.5$, respectively. Among the minerals present in root, potassium content was the highest. Total amino acid contents were $103.5{\pm}9.1$ mg/g. Palmitic acid was the most abundant fatty acid in AT root. The vitamin E and C levels in AT root were $1.1{\pm}0.1$ and $5.2{\pm}0.5$ mg/100 g, respectively. The antioxidant activity of 70% ethanol extract and fractions of the AT root has been determined by the scavenging of the stable radical DPPH; the result showed that the chloroform fraction was the most active, as the amount required for 50% reduction of DPPH after 30 min ($RC_{50}$) was $103.7{\mu}g$, followed by 70% ethanol extract ($265.4{\mu}g$), hexane fraction ($104.4{\mu}g$), ethyl acetate fraction ($104.4{\mu}g$), butanol fraction ($108.9{\mu}g$) and aqueous fraction ($484.1{\mu}g$).

This experiment was conducted on wild vegetables; Gondalbi (Cirsium setidens), Deoduck (Codonopsis lanceolata Trautv.), and Jandae (Adenophora triphylla var. Joponica Hara) seed to study whether priming with deep sea water results in enhancement of seed germination and identify the optimum concentration of the priming solution, and duration of priming. Seeds were primed with 5 various concentrations (5%, 10%, 15%, 20% and 30%) of deep sea water (DSW) in 12 hours, 24 hours, and 48 hours at $24^{\circ}C$. Since Jandae had seed dormancy, it was kept for four weeks in refrigerator at $2^{\circ}C$ after priming treatment. In Deoduck, 5 percentage DSW priming significantly improved the early germination percentage, radicle length, and plumule emergence percentage. Among the priming period of treatments, 24 hours priming showed better performance in this treatment whereas, in Jandae, 12 hours priming with 10 percentages DSW significantly improved the germination percentage and germination rate. This treatment had increased the final germination percentage by 54%, 15% and 40% compared with control, plain water and $KNO_3$ priming respectively. But in Gondalbi, priming did not improve the germination of seed. However, among the priming treatments, 12 hours priming with 3% $KNO_3$ and 20% DSW gave better performance. In both the wild vegetables; Deoduck and Jandae, priming in deep sea water had improved the germination percentage and germination rate as compare to plain water, $KNO_3$, and without priming treatment. Hence the best seed priming treatment on Deoduck and Jandae are 24 hours with 5% DSW and 12 hours with 10% DSW respectively.

This study was conducted to investigate photosynthetic characteristics of two-year-old of Adenophora triphylla var. japonicum grown under control (full sunlight) and three different shading treatment (25, 50, and 75% shading treatment). Total chlorophyll contents like chlorophyll a and b content had not significant difference among treatments. Net photosynthetic rate of control and 25% treatment were higher than 50% and 75% treatment. Seedlings grown under full sunlight showed the highest photosynthetic activity such as photosynthetic rate, stomatal conductance and intercellular $CO_2$ concentration except for water use efficiency which was relative higher under 50% and 75% treatment.

This study aimed to investigate the influence of Astragalus membranaceus (AM), Adenophora triphylla (AT), and Ulmus pumila (UP) extracts on the quality traits, palatability, and storage stability of sous-vide (SV) cooked chicken breasts. Chicken breasts were marinated in AM, AT, or UP extracts for 1 h, and then consistently cooked at a constant temperature of 60℃ for 2 h. SV cooked chicken breasts with the UP extract exhibited lower lightness and higher yellowness values on the surface region compared to those with the AM and AT extracts (p<0.05). The control and UP groups displayed a similar overall visual acceptability (p>0.05), although the UP group had lower color acceptability (p<0.01). The UP group also had higher flavor and lower off-flavor intensities compared to the control group (p<0.05), although similar scores were observed in tenderness attributes and juiciness among the groups (p>0.05). Owing to these results regarding overall sensory acceptability, samples from the UP group were more preferred by the trained panelists compared to samples from the control group (p<0.001). On 14 d of cold storage, all the groups with herbal medicinal extracts exhibited a lower concentration of thiobarbituric acid-reactive substances than the control group (p<0.05), and the AT and UP groups showed lower values compared to the AM group due to their higher flavonoid contents (p<0.001). Therefore, meat marination with herbal plant extracts before SV cooking can be effective for enhancing the overall quality of SV cooked chicken breast.

In 2020 and 2021, we surveyed diseases of three-leaf ladybell (Adenophora triphylla) plants grown in fields at two locations in Korea. During the disease surveys, severe leaf rot symptoms were observed on the young plants in Hongseong, and stem rot symptoms on the adult plants in Cheolwon. The incidence of leaf rot was 5-60%, and that of stem rot 1-10%. We obtained 6 fungal isolates each from the leaf rot lesions and the stem rot lesions. All the isolates were morphologically identified as Rhizoctonia solani. Anastomosis test and investigation of cultural features of the fungal isolates revealed that the isolates from the leaf rot lesions corresponded to R. solani AG-1(IB), and those from the stem rot lesions to R. solani AG-2-2(IIIB). Two isolates each of R. solani AG-1(IB) and AG-2-2(IIIB) were used for DNA sequence analysis and pathogenicity test to three-leaf ladybell plants through artificial inoculation. The anastomosis groups and cultural types of the R. solani isolates were confirmed by the sequence analysis. The pathogenicity tests revealed that the isolates of R. solani AG-1(IB) caused only leaf rot symptoms on the inoculated plants, and those of R. solani AG-2-2(IIIB) leaf rot and stem rot symptoms. The induced symptoms were similar to those observed in the fields investigated. Leaf and stem rot of three-leaf ladybell caused by the two anastomosis groups and cultural types of R. solani is first reported in this study.

The root of Adenophora triphylla is widely used as traditional herbal medicine in Korea. We studied its effects on sodium nitroprusside (SNP) cytotoxicity and antioxidant genes expression in HepG2 cells. To study whether Adenophora triphylla ethylacetate extract (ATea) inhibited NO-induced cell death, HepG2 cells were preincubated for 24 hr with 50 and 100 $\mu$g/mL ATea followed by 24-hr exposure to 0.5 mM SNP (exogenous NO donor). No-induced cytotoxicity was inhibited by pretreatment of ATea, as assessed by mitochondrial dehydrogenase activity (MTT assay). We further investigated the effects of ATea on mRNA levels of various enzymes of the antioxidant system such as Cu, Zn superoxide dismutase (SOD 1), Mn SOD (SOD 2), glutathione peroxidase (GPx), catalase and several enzymes of the glutathione metabolism [glutathione reductase (GR), $\gamma$-glutamyl-cystein synthetase (GCS), glutathione-S-transferase (GST), $\gamma$-glutamyltranspeptidase ($\gamma$-GT), glucose-6-phosphate dehydrogenase (G6PD)] by RT-PCR. CAT, GCS, GR and G6PD mRNA levels were increased after treatment with ATea. The SOD 1, SOD 2, GPx, GST and $\gamma$-GT mRNA levels were not affected in ATea-treated HepG2 cells. We concluded that ATea have an indirect antioxidant effects, perhaps via induction of CAT, GCS, GR and G6PD.
