[Abstract]
Object To study chemical constituents in the root of Salvia przewaskii Maxim. and examine their inhibitory activity on HIV-IN and HIV-RT. Methods Compounds were isolated and purified by chromatography. Their structures were determined by spectral analysis and chemical evidence. Anti-HIV activities of the compounds were observed in vitro. Results Four compounds were obtained. Their structures were identified as benzenepropanoic acid, 8-{[7′-(3′, ′4-dihydroxy-phenyl)-9′-oxo-7′-propenyl]oxy}-3-(1″-O-β-D-glucopyranosyl)-4-hydroxy-[R-(E)] (Ⅰ), rosmarinic acid (Ⅱ), lithospermic acid (Ⅲ), and lithospermic acid B (Ⅳ).Conclusion Compound Ⅰ is a new one, Ⅱ-Ⅳ are the known compounds with the anti-HIV effects.
