概要
- 論文の詳細を見る
Four novel withanolide-type steroids named cilistols p, pm, p1 and u (1-4, respectively), were isolated from the leaves of Solaum cilistum. The respective structures were characterized by spectroscopic means as follows : cilistol p (1) was (22R, 24R, 25R, 26S)-1-oxo-22, 26-epoxy-3α, 5α-cycloergostane-6β, 17α, 24, 25, 26-pentaol 26-O-β-D-glucopyranoside, cilistol pm (2) corresponded to the 6-O-methyl ether derivative of 1 ; cilistol p1 (3) was represented as the 24-O-methyl ether of 1, and cilistol u (4) was shown to be the epoxide between C-24 and -25, presumably bearing cilistols p, pm and p1 by ring-opening.
