  • Sclerotinia rot was occurred on the leaf and stem of Peucedanum japonicum Thunb. in greenhouse field of Pohang city of Gyeongbuk province in Korea. The typical symptom of the disease was light brown spot and tipburn on infected leaves. The colony of the isolated fungus was white to light gray in color. Asci were cylindrical shape and 75-240×5.9-17.3 ㎛ in size. Apothecia were cup-shaped with numerous asci and 0.5-0.9 cm in size. Ascospores were aseptate and ellipsoid in shape, and 8.4-10.7×4.8-5.8 ㎛ in size. Sclerotia formed on the plants and potato dextrose agar medium were globose to irregular in shape and black in color. Partial sequencing of rDNA of this isolate showed that it was 100% consistent with that of Sclerotinia sclerotiorum. It was confirmed that the same lesion was formed by reinoculating this pathogen on a healthy P. japonicum Thunb. and the same strain was isolated. This is the first report on the Sclerotinia rot of P. japonicum Thunb. caused by S. sclerotiorum in Korea.

  • 3',4'-Disenecioylkhellactone is one of khellactone-type coumarins isolated from the roots of Peucedanum japonicum Thunb. However, its pharmacological effects are still little understood. In the present study, we investigated the inhibitory effect of 3',4'-disenecioylkhellactone on growth of gastric cancer cells. 3',4'-Disenecioylkhellactone strongly suppressed cell proliferation and induced caspase-mediated apoptosis in AGS human gastric cancer cells. Analysis of phospho-antibody arrays revealed 3',4'-disenecioylkhellactone effectively suppressed signal transducer and activator of transcription 3 (STAT3) tyrosine phosphorylation. 3',4'-Disenecioylkhellactone decreased STAT3 translocation to the nucleus and expression of STAT3 target genes. In addition, we examined the level of STAT3 activation in several gastric cancer cells and found that the inhibition of STAT3 phosphorylation by 3',4'-disenecioylkhellactone was associated with gastric cancer cell proliferation. Taken together, this study provides evidence for the first time that 3',4'-disenecioylkhellactone may be a potential therapeutic agent for the prevention or treatment of gastric cancer.

  • This study was conducted to investigate the changes in the physicochemical properties of Peucedanum japonicum Thunb. after blanching. After blanching treatment, the crude protein content decreased but did not affect the crude fat, crude ash and carbohydrate contents of P. japonicum. All the detected free sugar contents decreased after blanching, but the total free sugar content decreased by 14.8% from that of the raw P. japonicum after blanching. The total amino acid and essential amino acid contents of the blanched P. japonicum. decreased by 10.75% and 15.22% from those of the raw P. japonicum. There were no differences in the contents of the total fatty acid between the raw and blanched P. japonicum. The total organic acid content decreased by 37.03% from that of the raw P. japonicum. after the blanching, and the reduction of the acetic acid was largest in the organic acid. The vitamin A, C and E contents decreased by 20.20%, 8.23% and 35.59% after the blanching. The total mineral content of the blanched P. japonicum. decreased by 21.84% after the blanching. The nutrients in the P. japonicum were essential amino acid, vitamin C, minerals, but these were reduced after the blanching. Therefore, the blanching conditions that can reduce nutrient loss of P. japonicum must be established.

  • This study was conducted to isolate a compound with anticancer properties from the roots of Peucedanum japonicum Thunb. (Umbelliferae), and to evaluate the efficacy of that compound's anticancer activity. The $CHCl_3$ layer was purified via repeated column chromatography and recrystallization. The two compounds isolated from $CHCl_3$ layer were identified via NMR spectroscopic analysis as (10E) 1,10-heptadecadiene-4,6-diyne-3,8,9-triol (Comp. I) and anomalin (Comp. II). (10E) 1,10-heptadecadiene-4,6-diyne-3,8,9-triol was the first report from the roots of P. japonicum. MTT assays were conducted to evaluate the in vitro cytotoxic activities of Compounds I and II against the following human cancer cell lines: HeLa, HepG2, SNU-16, and AGS. Comp. I evidenced the most profound cytotoxic activity against HepG2 cells ($IC_{50}=6.04{\mu}g/mL$), and Comp. II exhibited the most profound cytotoxic activity against SNU-16 cells ($IC_{50}=18.24{\mu}g/mL$) among the human cancer cell lines tested in this study. However, no significant cell death was observed in the CCD-25Lu human normal lung fibroblast cells. Quantitative analysis using UPLC (Ultra Performance Liquid Chromatography) showed that the roots of P. japonicum contained 0.015 (Comp. I) and 1.69 mg/g (Comp. II) of these compounds.
