Abstract
An investigation on the chemical constituents of the 90% EtOH extract of Perovskia atriplicifolia led to the isolation of fifteen compounds from the EtOAc fraction. Based on the detailed spectral analysis (MS, 1D and 2D NMR), as well as comparison with the literatures, the structures of compounds 1-15 were determined as cirsimaritin (1), salvigenin (2), syringaldehyde (3), vinyl caffeate (4), 2α, 3α-dihydroxyolean-12-en-28-oicacid (5), 2α, 3α-dihydroxyurs-12-en-28-oicacid (6), niga-ichigoside F1 (2α, 3β, 19α, 23- tetrahydroxyurs - 12-en-28-oicacid- O-β-D- glucopyranoside, 7), sericoside (8), 4-epi-niga-ichigoside F1 (2α, 3β, 19α, 24-tetrahydroxyurs-12-en-28-oicacid O-β-D-glucopyranoside, 9), 2α, 3β, 24-trihydroxyolean-12-en-28-oicacid O-β-D-glucopyranosyl-(1 --> 2) - β-D-glucopyranoside (10), pruvuloside A (11), asteryunnanoside A [2α, 3β, 23-trihydroxyolean-12-en-28-oicacid O-β-D-glucopyranosyl-(1 --> 2)-β- D- glucopyranoside,12], rosmarinic acid methyl ester (13), β-sitosterol (14), and daucosterol (15), respectively. Compounds 1-13 were isolated from the Perovskia genus for the first time. All the compounds were obtained from P. atriplicifolia for the first time.
