Abstract:
To study the chemical constituents of Peperomia dindygulensis Miq. , chromatography was used to isolate and purify the chemical constituents, their structures were elucidated by spectroscopic data and physical-chemical properties. Three compounds were obtained. They were identified as: hypolacetin-4',7-dimethyl ether-8-O-beta-D-glucopyranoside (I) , isoscutellarein-4'-methyl ether-8-O-alpha-L-arabinopyrano-syl-(1--> 4)-beta-D-glucopyranoside ( II) , isoscutellarein-4', 7-dimethyl ether-8-O-alpha-L-arabinopyranosyl-(1-->4) -betea-D-glucopyranoside (III). Compounds I, II and III are all new compounds.
