Codonopsis lanceolata L. (Campanulaceae) has long been used in traditional Korean medicine to treat bronchitis, cough, and inflammatory diseases, however, the efficacy of anti-tumor activities remains to be defined. In this study the effects of Codonopsis lanceolata (C. lanceolata) on proliferation, migration and adhesion in lung (A549, H1299) and ovarian cancer (SKOV-3) cells were investigated. To assess and compare the pharmacological effects and production places of C. lanceolata, the ethanolic extracts of C. lanceolata from different places in Korea (Hongseong, Yecheon, Yeongwol, Yanggu, Gangjin, and Hoengseong) were prepared. The extract from Hoengseong county did have only marginal anti-proliferative activity in all the cell lines tested, however, other extracts had little or no effect on cell proliferation. The extracts from Hongseong, Gangjin or Hoengseong county had partial anti-migratory activity in lung cancer cells, but not in ovarian cancer cells. In addition, the extract from Hoengseong county had partial anti-adhesive activity in ovarian cancer cells, however, other extracts did not affect cell adhesion in both lung and ovarian cancer cells. Taken together, these findings provide the first description of anti-tumor efficacy of C. lanceolata from different production places in Korea, and suggest that C. lanceolata from Hoengseong county may have therapeutic potential in lung and ovarian cancers.

Ginseng has been recognized as a lifespan extending medicine which has been regarded as one of the medicines classified as top medicines, as the Boncho (medical herbs) study which is influenced by the idea of guidance's costume and food concept mainly in China is gaining its bona fide form. As the demand for ginseng has been expanded to other levels, the demand for ginseng has been increasing. Ginseng from the nature reached its supply chain limit due to its extinction and difficulty of picking, so it translated into ginseng cultivation of economy rather than harvesting in nature. After the start of ginseng cultivation, the ginseng cultivation was further enhanced by the rapid development of processing methods such as white-ginseng and red-ginseng, and the surge of consumption due to the traditional belief in ginseng drug efficacy and support of scientific research. In the Joseon Dynasty, the name Gasam (cultivated ginseng) had been created as ginseng was cultivated on farmland after the stage of SanYang (wild cultivated ginseng), the purpose of the new name Gasam is to differentiate from natural ginseng, and natural ginseng lost its firm position as the genuine ginseng as the Gasam replaced the genuine ginseng, and the natural ginseng got a new name of SanSam (wild ginseng). Because the real ginseng substance concept dissipated, and as Gasam is being called ginseng, the name Gasam was also disappeared. As a result, it was possible to grow large quantities according to the arrival of the Gasam era, and it was possible to supply the demand for ginseng, and it could become one agricultural industry. In this ginseng cultivation, in Japan where ginseng did not grow naturally, it was difficult to obtain ginseng from Joseon and faced with a shortage of ginseng at all times. Therefore, the shogun cultivated the Gasam systematically at the national level by the inside of the shogunate. However, since the natural ginseng is native to China and Korea, there is a concern about the deterioration of the quality of natural ginseng due to the incorporation of cultivated ginseng (Gasam). To protect the interests, the cultivation of ginseng was subject to control. For this reason, the lack of historical information on Gasam cultivation, which had to be started secretly, would be a natural result. In this paper, althouh not sufficient enough, the historical informations were used to summarize the history of ginseng cultivation in China, Japan and Korea.

Baicalein is one of the main flavonoids derived from roots of Scutellaria baicalensis Georgi, a traditional Oriental medicine. Although baicalein has high antitumor effect on several human carcinomas, the mechanism responsible for this property is not unclear. In this study, the data revealed that baicale-ininduced growth inhibition was associated with the induction of apoptosis connecting with cytochrome c release, down-regulation of anti-apoptotic Bcl-xl and increased the percentage of cells with a loss of mitochondria membrane permeabilization. Baicalein also induced the proteolytic activation of caspases and cleavage of PARP; however, blockage of caspases activation by z-VAD-fmk inhibited baicalein-induced apoptosis. In addition, baicalein enhanced the formation of autophagosomes and up-regulated LC3-II/LC3-I ratio. Interestingly, the pretreatment of bafilomycin A1 recovered baicalein-induced cell death suggesting that autophagy by baicalein roles as protective autophagy. Taken together, our results indicated that this flavonoid induces apoptosis and cell protective autophagy. These data means combination treatment with baicalein and autophagy inhibitor might be a promising anticancer drug.

The influenza neuraminidase (NA, E.C. 3.2.1.18), an antiviral, has been the target of high pharmaceutical companies due to its essential role in viral replication cycle. Perilla frutescens (P. frutescens) is used in traditional Chinese medicine for various diseases, such as cold due to wind-cold, headache and cough. In this context, four major polyphenolic compounds including rosmarinic acid-3-O-glucoside (1), rosmarinic acid (2), luteolin (3), and apigenin (4) isolated from P. frutescens were evaluated for their inhibitory effect on recombinant virus H1N1 neuraminidase (rvH1N1 NA). Among the test compounds, rosmarinic acid and luteolin inhibited the rvH1N1 NA with an $IC_{50}$ of 46.7 and $8.4{\mu}M$, respectively. The inhibition kinetics analyzed by the Dixon plots indicated that rosmarinic acid and luteolin were noncompetitive inhibitors and that the inhibition constant, $K_I$, was established as 43.9 and $14.3{\mu}M$, respectively. In addition, 578 genetically diverse accessions and 39 cultivars of P. frutescens were analyzed using HPLC to characterize the diversity of polyphenolic composition and concentration. The individual and total compositions exhibited significant difference (P < 0.05), especially rosmarinic acid which was detected as the predominant metabolite in all accessions (58.8%) and cultivars (62.8%). Yeupsil and Sangback cultivars exhibited the highest rosmarinic acid ($3,393.5{\mu}g/g$) and luteolin ($383.3{\mu}g/g$) content respectively. YCPL177-2 with the high concentration ($889.8{\mu}g/g$) of luteolin may be used as a genetic resource for breeding elite cultivars.

Background: Rehmannia glutinosa is a perennial herb belonging to the family Scrophulariaceae and is used in traditional oriental medicine. This study was conducted to evaluate the appropriateness of plug-seedling cultivation for replanting of R. glutinosa. Methods and Results: The seed rhizomes of Rehmannia glutinosa 'Jihwang 1' were harvested in the middle of March, 2018. Direct seedling cultivation was conducted after air curing for 3 days. The seedlings for transplanting were cultivated for 30 (30D), 45 (45D), and 60 days (60D). The mat formation rates of the 30D, 45D and 60D treatment seedling were 81.3%, 100%, and 100%, respectively. Of the tree treatment groups, flowering occurred only in the 45D and 60D treatment groups, and their flowering rates were $7.3{\pm}3.06%$ and $13.3{\pm}1.15%$, respectively. The agronomic characteristics and active components of the three treatment groups were evaluated in comparison with the DS1 (directly seeded group, control) and DS2 (directly seeded group, replanting) groups. As a result, the leaf length and leaf width of the 30D seedlings were higher than other treatment groups, but the number of leaves per plant was statistically the same. In addition, root diameter and yield of the 30D seedling were statistically the same as DS1. Moreover the catalpol contents of 30D, 45D, DS1 and DS2 group seedlings were 2.23%, 1.86%, 2.50% and 2.08%, respectively. Conclusions: Taken together, these findings suggest it is feasible to use the plug-seedling cultivation method for replanting of R. glutinosa. seedlings. However, further evaluation of the economic aspect is needed.

Inflammatory and oxidative stimuli play a critical role not only in the process of transforming normal cells into cancer cells, but also in the proliferation process of cancer cells. Sipyukmiryukieum (SYMRKU), a traditional Korean herb-combined remedy, is composed of 16 kinds of herbal medicines, which were recorded for "Ongjeo" treatment in "Dongeuibogam". In this study, we investigated the inhibitory effect of SYMRKU against inflammatory and oxidative responses in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. Our results showed that SYMRKU significantly inhibited LPS-induced secretion of pro-inflammatory mediators including nitric oxide (NO) and prostaglandin $E_2$ without showing any significant cytotoxicity. Consistent with these results, SYMRKU down-regulated LPS-induced expression of their regulatory enzymes such as inducible NO synthase and cyclooxygenase-2. SYMRKU also inhibited LPS-induced production and expression of pro-inflammatory cytokines such as tumor necrosis factor-${\alpha}$, interleukin (IL)-$1{\beta}$ and IL-6. In addition, SYMRKU significantly reduced the production of reactive oxygen species by LPS and showed a strong, which was associated with induction of nuclear factor erythroid 2-related factor 2 and heme oxygenase-1 expression. Although further studies are needed to fully understand the anti-inflammatory effects associated with the antioxidant capacity of SYMRKU, the findings of the current study suggest that SYMRKU may have potential benefits by inhibiting the onset and/or treatment of inflammatory and/or oxidative diseases.

Portulaca oleracea L. (PL) has been used in traditional medicine herb for treatment of various diseases, such as diarrhea, dysentery, and skin inflammation. Previous studies have shown that the PL regulates the inflammation by inhibition of pro-inflammatory cytokines. Although PL might have improvement effects of intestinal function and bioactive effects, there are not enough studies to demonstrate. This study investigated the effects of KDC16-2 on the improvement of intestinal function and anti-inflammatory effects in vivo and in vitro. The improvement effect of intestinal function was measured fecal amount, water content and intestinal transit rate in KDC16-2 treated ICR mice. As results, compared with the control group, the KDC16-2 group showed a significant increase in wet fecal weight, dry fecal weight and fecal water content. The intestinal transit rate of KDC16-2 group was significantly increased. Based on the results, KDC16-2 is considered to have effects on improving intestinal function. The effect of anti-inflammatory demonstrated by using dextran sulfate sodium (DSS)-induced colitis mice. The mice were administered 3% DSS along with KDC16-2 (100, 300 mg/kg) for 14 days. DSS-induced colitis mice were significantly ameliorated in KDC16-2 treated group, including body weight loss, colon length shortening, tight junction protein of colon and histological colon injury. The levels of inflammatory mediators (IgG2a, IgA, C-reactive protein and Myeloperoxidase) and pro-inflammatory cytokines (tumor necrosis factor (TNF)-${\alpha}$, Interleukin (IL)-6) which are involved in inflammatory responses were increased in the DSS-treated group as compared to those in the control group, and the levels were significantly decreased in the KDC16-2 groups. In addition, we investigated the impact of KDC16-2 on lipopolysaccharide (LPS)-induced inflammatory responses in J774A.1 cells. KDC16-2 inhibited production of prostaglandin E2 (PGE2) and reactive oxygen species (ROS). These results suggested that the KDC16-2 could effectively alleviate the dysfunction of intestinal and inflammatory mediators. Thus, these KDC16-2 can be potentially used as health functional food of intestinal.
