Abstract

From the aerial part of Cuphea hyssopifolia (Lythraceae) diterpenes and flavonoids were isolated. The compounds were identified as: friedelan–3β–ol 1, ursolic acid 2, methyl gállate 3, quercetin 4, quercetin–3–O–α–rhamnopyranoside 5, 1,2,3,4,6–penta–O–galloyl–β–D–glucose 6 and manitol 7.

Keywords: Cuphea, Lythraceae, flavonoid, triterpene, NMR.
