Abstract

Abstract:

Objectives: To investigate bioactive compounds from Carica papaya pulp. Methods: Chemical components in Carica papaya pulp was extracted using 85% ethanol and purified by marcoporous resin adsorption followed by ODS and MCI column chromatography. The structures of these compounds were elucidated through NMR spectroscopic analysis. Results: Three compounds were isolated from Carica papaya pulp and their chemical structures were identified as 2β, 3β-dihydroxy-ursolic acid (Ⅰ); 3-O-glycoside-sterol (II); diosgenin-3-O- β-D-glucopyranosyl(1 → 3)- β-D-glucopyranosyl(1 → 4)-[α-Lrhamnopyranosyl(1 → 2)]- β -D-glucopyranoside (III), respectively. Conclusion: To the best of our knowledge, this paper is the first one that reports compounds I － III obtained from Carica papaya pulp.

Key words: Carica papaya, isolation, ursolic acid, glycoside-sterol, steroidal saponin
