Homoisoflavonoids and the Antioxidant Activity of Ophiopogon japonicus Root
The root of Ophiopogon japonicus has been used as a traditional Chinese medicine and also a functional food ingredient for a long time in China. In the present study, 17 different homoisoflavonoid compounds were identified in the root extract of O. japonicus by HPLC–DAD and LCMS/MS analyses. The antioxidant activity of the of chloroform/methanol (1:1, v/v), methanol and 70% ethanol extracts, an...

متن کاملPreparative isolation of three anthraquinones from Rumex japonicus by high-speed counter-current chromatography.
Three anthraquinones--emodin, chrysophanol, and physcion--were successfully purified from the dichloromethane extract of the Chinese medicinal herb Rumex japonicus by high-speed counter-current chromatography (HSCCC). The extract was separated with n-hexane-ethanol-water (18:22:3, v/v/v) as the two-phase solvent system and yielded 3.4 mg of emodin, 24.1 mg of chrysophanol, and 2.0 mg of physcio...
