This study was conducted to investigate the effect of fermentation on biological activity of Chelidonium majus var asiaticum and to screen effective starter culture strains. Antibacterial activity against to Staphylococcus aureus, Listeria monocytogenes and Salmonella gallinarum and antioxidant activity as free radical scavenging activity by using DPPH were tested. Total six starter culture strains, two of Lactobacillus brevis, one of Lactobacillus plantarum and three of Saccharomyces cerevisiae were used. Plant extract was prepared after fermentation by using ethanol. All strains showed normal growth in viable cell counts of fermented cultures and L. plantarum showed the highest cell growth significantly (p<0.05). In antibacterial activities of extracts, the activity was found only in the extract from the fermentation using L. plantarum. In antioxidant activity, the highest activity was shown in the fermentation using L. plantarum significantly (P<0.05). Newly produced spots in two of three elution systems on TLC-DPPH test were detected in the fermentation using L. plantarum.

In this study, we set up an analytical method that can be used for rapid and accurate determination of representative isoquinoline alkaloids in medicinal plants using UPLC-ESI-Q-TOF MS (ultra pressure liquid chromatography-electrospray ionization-quadrupole-time-of-flight mass spectrometry). The compounds were eluted on a C18 column with 0.1 % formic acid and acetonitrile, and separated with good resolution within 13 min. Each of the separated components was characterized by precursor ions (generated by ESI-Q-TOF) and fragment ions (produced by collision-induced dissociation, CID), which were used as a reliable database. We also performed method validation: analytes showed excellent linearity ($R^2$, 0.9971-0.9996), LOD (5-25 ng/mL), LOQ (17-82 ng/mL), accuracy (91.6-97.4 %) as well as intra- and inter-day precisions (RSD, 1.8-3.2 %). In the analysis of Chelidonium majus L., magnoflorine, coptisine, sanguinarine, berberine and palmatine were detected by matching retention times and characteristic fragment ion patterns of reference standards. We also confirmed that, among the quantified components, coptisine was present in the highest quantity. Furthermore, alkaloid profiling was carried out by analyzing the fragment ion patterns corresponding to peaks of unknown components. In this manner, protopine, chelidonine, stylopine, dihydroberberine, canadine, and nitidine were tentatively identified. We also proposed the molecular structure of the fragment ions that appear in the mass spectrum. Therefore, we concluded that our suggested method for the determination of major isoquinoline alkaloids by UPLC-Q-TOF can be useful not only for quality control, but also for rapid and accurate investigation of phytochemical constituents of medicinal plants.

Human neutrophil elastase (HNE) represents a good therapeutic target for the treatment of inflammatory diseases as well as invasion of microorganism. The methanol extract of a aerial part of Chelidonium majus L. showed high activity against the neutrophil elastase with an $IC_{50}$ value of $100{\mu}g/mL$. Due to its potency, subsequent bioactivity-guided fractionation of methanol extract led to six alkaloids (1-6), which were identified as dihydrosanguinarine (1), (s)-stylopine (2), arnottianamide (3), (+)-chelidonine (4), spallidamine (5), and N-trans-feruloyltyramine (6). Among of them, three alkaloids (2, 5, and 6) inhibited HNE in a dose-dependent manner with $IC_{50}$ ranging between 11.6 and $51.0{\mu}M$. Lineweaver-Burk and Dixon plots, and their secondary replots showed that alkaloids (2, 5, and 6) were mixed inhibitors of HNE. The analysis of $K_I$ and $K_{IS}$ value proved that all inhibitors (2, 5, and 6) had reversible mixed type I mechanism.

The modifying effects of Chelidonium majus L/(Papaeracea)herb extract(CH) ,and analgesic traditionally prescribed for gastric and duodenal ulcer patients, on gastric tumor development given Ν-methyl-Ν'-nitro-Ν-nitrosogyanidine(MNNG) were studied in sixty-four 6 week-old male Wistar rats. Group 1 rats were ini-tially given MNNG(200mg/kg b/w.) by gavage ar days 0 and 14 as well as saturated sodium chloride solution(S-NaCI, 1ml per rat) every 3 days during weeks 0 to 3(6 times) and then placed on basal diet containing 0.1 or 0.2% CH ofr 16 weeks from week 4. Rats of Groups 2 and 3 were treated with MNNG together with S-NaCI or saline(0.9% NaCI, 21ml per rat) respectively, timed as in Group 1 but without further treatment. All survival animals were killed at week 20 and histopathologically investigate. in the glandular stomach, the number of preneoplastic pepsinogen 1 altered pyloric glands(PAPGs) in the MNNG+S-NaCI→CH(0.1%) group(Group 1) was significantly smaller than in the MNNG+S-NaCI group(Group 2)(p<0.02). The inci-dences of forestomach neoplastic lesions (Papillomas and squamous cell carcinomas)also showed a tendency for decrease with the CH treatment. The results thus indicate that C"H exerts inhibitory effects on glandular for decrease with the CH treatment. The results thus indicate that CH exerts inhibitory effects on glandular stomach carcinogenesis in the rat, so that it may have potential as a chemopreventive agent for stomach cancer in man.

The demand for Chelidonium majus L. subsp. asiaticum H. Hara is expected to increase due to its pharmacological properties such as antibacterial, antioxidant, and anti-inflammatory effects. However, an effective propagation system for this species has not yet been established. This study was conducted to analyze the seed dormancy and germination characteristics of C. majus L. subsp. asiaticum H. Hara native to Korea and establish a mass propagation system. The dormancy type was primarily classified by analyzing the general information of the collected seeds. The seed dormancy breaking was investigated by comparing the effects of cold stratification (0, 2, 4, 8, 10, or 12 weeks) with warm stratification (S, summer temperature, 25/15℃) and intermediate temperature stratification (A, autumn temperature, 15/10℃) of alternating temperature stratification (S12-A4 or S12-A8 weeks). After dormancy break, 500 mg/L GA₃ and GA₄₊₇ treatment replaced cold stratification and improved seed germination. The results of this study are expected to provide basic data for future seed propagation and mass propagation by analyzing the dormancy and germination characteristics of C. majus L. subsp. asiaticum H. Hara seeds.
