This study was to investigate catalpol content and antioxidant activities in five cultivars (Kokang, Suwon 10, Suwon 11, Jiwhang 1 and Korea) of Rehmannia Radix. Catalpol content was analysed by HPLC using $C_{18}$ column ($150{\times}4.6\;mm$, $5{\mu}m$), 1% acetonitrile and a UV detector. The standard curve was found to be a linear regression of y=0.0483x-0.0841 ($R^2$=0.999). The catalpol content ranged from 85.2 mg/g to 144.9 mg/g, of which the Korea was the highest among cultivars. The total phenol content in Rehmannia Radix was 0.358~0.459 mg/g, of which the Korea was the highest among cultivars. The antioxidant activities determined by DPPH and hydroxyl radical scavenging activities were the highest in Korea with $IC_{50}$ of 205.8 mg/g for DPPH radical scavenging activity and $IC_{50}$ of 38.8 mg/g for hydroxyl radical scavenging activity. Based on these results, the Korea among Rehmannia Radix cultivars was suggested to be a potent medicinal plant material for antioxidant activities.

The aim of this study was to investigate the apoptotic effect and its mechanism on Radix Aconiti (RA) extract in HL-60 human leukemia cell line. RA extract induced apoptosis as confirmed by discontinuous fragmentation of DNA. To clarify the mechanisms on RA extract-induced apoptosis, we examined the caspase-3, -8 enzyme activity and protein levels including Fas, FasL in HL-60 cells. Treatment with RA extracts resulted in the increase of caspase-3 enzyme activity in a time and dose-dependent manners, which was accompanied by the cleavage of poly-(ADP-ribose) polymerase (PARP). This activation of caspase-3 enzyme resulted from cleavage of procaspase-8, which was followed by increases of FasL, Fas protein expression in RA extracts-treated HL-60 cells. In conclusion, RA extract induced apoptosis of HL-60 human leukemia cell line. This results suggest that the apoptotic mechanisms of RA extract on HL-60 cells involved in FasL, Fas activation, procaspase-8 cleavage, activation of caspase-3 and cleavage of PARP. Collectively, these results suggest that RA may be a valuable agent as a anti-cancer drug.

The water extract of Scutellariae radix was treated to rat and the primary culture of hepatocytes, and the expressions of several glutathione S-transferase (GST) isozymes and the activity of GST Yc1/2 were investigated by Western blot and by the use of HPLC. The results were obtained as follows: The water extract of Scutellariae radix did not induce the expressions of cytosolic GST Ya and GST Yp in rat livers. But, the extract increased the expression of cytosolic GST Yc1/2 to 2-4 fold higher than control. The expression of GST Yc1/2 in the primary culture of rat hepatocytes was induced by the water extract of Scutellariae radix in a dose-dependent manner, reaching 21-fold over control with 50 ㎍/㎖ treatment. The induction of the expression of GST Yc1/2 in rat livers increased the formation of AFB₁-glutathione conjugate from AFB₁-8,9-epoxide which was made in the metabolism of AFB₁.

Background: In this study, the radix of Astragalus membranaceus Bunge extract fermented by Saccharomyces cerevisiae, Weissella cibaria, and Pediococcus pentosaceus to increase the levels of isoflavonoid aglycone contents. Methods and Results: In order to change the in isoflavonoids, we fermented the radix of A. membranaceus extracts with microorganisms that have β-glucosidase activity. Besed on the β-glucosidase activity, we selected three strains, Weissella cibaria, Pediococcus pentosaceus, and Saccharomyces cerevisiae. HPLC analysis revealed that the levels of isoflavonoid aglycones were increased in all fermentation cases, and the extracts fermented by S. cerevisiae showed the highest levels of isoflavonoid aglycones. We evaluated the antioxidant activity, anti-wrinkle effects and whitening effects of the S. cerevisiae-fermented extracts using the DPPH assay, tyrosinase inhibition activity assay, and collagenase inhibition activity assay. We confirmed higher activity in S. cerevisiae-fermented extracts than in control, with the half maximal inhibitory concentration (IC₅₀) value of 565.1 ± 59.1 ㎍/㎖ in DPPH radical scavenging activity, tyrosinase inhibition rate of 78.4 ± 0.9%, and collagenase inhibition rate of 83.8 ± 1.1%. Conclusions: We selected three stains of microorganisms showing high β-glucosidase activity, W. cibaria, P. pentosaceus and S. cerevisiae. Isoflavonoid glycones in the radix of A. membranaceus were converted to isoflavonoid aglycones by fermentation. In addition, the fermented radix of A. membranaceus exhibited antioxidant activity, anti-wrinkle effect, whitening effect and radical scavenging activity.
