[The structure and absolute configuration of vertaline B isolated from Veratrum taliense Lose. f].
摘要
Three steroidal alkaloids were isolated from the total plant of Veratrum taliense Lose. f. collected in Yunnan province, China. By means of MS, ~1HNMR, ~(13)CNMR and physical constants, the study proved Ⅱ to be jervine, Ⅲ to be stenophylline B and established the structure of a new alkaloid——vertaline B(Ⅰ). The absolute configuration of Ⅰ was determined by X-ray as (20R, 22R, 25S) 22,26-epiminocholest-5-ene-3β-16β, 20β, -triol.
