Homocyclotirucallane and Two Dihydrophenanthrenes from Spiranthes sinensis

Abstract

A novel homocyclotirucallane, sinetirucallol (1), and two additional new dihydrophenanthrenes, sinensols G (2) and H (3), were isolated from the aerial parts of Spiranthes sinensis (PERS.) AMES. Their structures were determined by various spectral analyses, including MS and two-dimentional nuclear magnetic resonance techniques. The structure of compound 1 was further confirmed by single-crystal X-ray analysis. The absolute configuration of I was determined by modified Mosher's method.
