Sulfur-containing sesquiterpenes from Thapsia villosa

摘要

Three new sesquiterpenoids bearing sulfurated ester groups have been isolated from the roots of Thapsia villosa L. Their structures have been elucidated by spectroscopic means. This is the first time that a methylthiopropionic acid ester is isolated from natural sources. (C) 2003 Elsevier Ltd. All rights reserved. [References: 16]
