Genotoxicity testing of Persicariae Rhizoma (Persicaria tinctoria H. Gross) aqueous extracts
Persicariae Rhizoma (PR) has been used as an anti-inflammatory and detoxification agent in Korea, and contains the biologically active dyes purple indirubin and blue indigo.

متن کامل24-Epibrassinolide from Gypsophila perfoliata
Brassinosteroids are a class of naturally occur ring phytohormones with high biological activity found in a wide variety of higher plants (Adam and Petzold, 1994; Adam et al., 1996; Cutler et al., 1991; Sakurai and Fujioka, 1993). Brassinosteroids occur only in trace amount (ngto ^ig/kg plant material). Therefore, their purification has to be monitored by a sensitive bioassay (Wada et al., 198...
