  • Title: cis-Eudesmane sesquiterpene glycosides from Liriope muscari and Ophiopogon japonicus.
    Author: Cheng ZH, Wu T, Bligh SW, Bashall A, Yu BY.
    Journal: J Nat Prod; 2004 Oct; 67(10):1761-3. PubMed ID: 15497959.
    Abstract:
    Two new cis-eudesmane sesquiterpene glycosides, liriopeoside A (1) and ophiopogonoside A (2), were extracted and purified from tubers of Liriope muscari and Ophiopogon japonicus, respectively, along with three known compounds. Their structures were elucidated as 1beta,6beta-dihydroxy-cis-eudesm-3-ene-6-O-beta-D-glucopyranoside (1) and 1beta,4beta,6beta-trihydroxy-cis-eudesmane-6-O-beta-D-glucopyranoside (2) by spectral data analysis. The structure and the relative configuration of compound 1 were confirmed by X-ray crystallographic analysis. This is the first time that cis-eudesmane-type sesquiterpenes have been reported from the genera Ophiopogon and Liriope.
