Isolation and Structure Elucidation of Three Glycosides and a Long Chain Alcohol from Polianthes Tuberosa Linn

Abstract

Three glycosides and a long chain alcohol were isolated from the bulbs of Polianthes tuberosa , these were identified as 3,29-dihydroxystigmast-5-ene-3- O - g - d -galactopyranoside ( 1 ) 1 , ethyl g - d -galactopyranoside ( 2 ), ethyl- f - d -galactopyranoside ( 3 ), and 1-tricosanol ( 4 ). The structures were determined by extensive spectroscopic and chemical methods. All four isolated compounds were screened for their cytotoxicity, antibacterial and antifungal activities, none of the compounds showed any significant activity.
