OBJECTIVE
To study the chemical constituents of Androsace umbellata.
METHOD
Many chromatography means were used in separation and purification, and the structures of all compounds were identified by the means of spectroscopic analysis and physico-chemical properties.
RESULT
10 compounds were elucidated as kaempferol 3-O-(3-O-acetyl-)-alpha-L-rhamnopyranoside(1), kaempferol 3-O-(2-O-acetyl-)-alpha-L-rhamnopyranoside(2), kaempferol 7-O-alpha-L-rhamnopyranoside(3), kaempferol 3-O-alpha-L- rhamnopyranoside(4), kaempferol 3-O-beta-D-glucopyranoside(5), kaempferol 3-O-(3-O-acetyl-)-a-L-rhamnopyranosyl-7-O-alpha-L- rhamnopyranoside(6), kaempferml 3-O-(4-O-acetyl-)-alpha-L-rhamnopyranosyl-7-O-alpha-L-rhamnopyranoside(7), quercetin 3-O-alpha-L- rhamnopyranoside(8), quercetin 3-O-beta-D-glucopyranoside(9) and myricetin 3-O-beta-D-glucopyranoside (10), respectively.
CONCLUSION
All compounds were obtained from the title plant for the first time.
