[Anthraquinones and triterpenoids from roots of Knoxia roxburghii].[Pubmed: 25775799]


Nine compounds were isolated from an ethanol extract of the roots of K. roxburghii by using a combination of various chromatographic techniques including column chromatography over silica gel, MCI gel, Sephadex LH-20, and reversed-phase HPLC. On the basis of physical-chemical properties and spectroscopic data analysis, their structures were identified as munjistin (1), 1-methoxy-3,6-dihydroxy-2-hydroxymethyl-9,10-anthraquinone (2), 1,2,3-trihydroxy-9,10-anthraquinone (3), arjunolic acid (4), hyptatic acid-A (5), hyptatic acid-B (6), 2α,3β,24-trihydroxyurs-12-en-28-oic acid (7), 2α,3β,23-trihydroxyurs-12-en-28-oic acid (8), and daucosterol (9). Compounds 1-9 were obtained from this genus for the first time.
