Four new diterpene glucosides, namely perovskiaditerpenosides A – D (1 – 4), were isolated from the BuOH extract of Perovskia atriplicifolia. Their structures were well elucidated by chemical methods and comprehensive spectroscopic analyses including MS, IR, and NMR (1D and 2D). The newly isolated compounds were screened for their cytotoxic activity against HepG2, NB4, HeLa, K562, MCF7, PC3, and HL60...
A novel terpenoid, named perovskiaol (1), was isolated from the cultured Perovskia atriplicifolia. Its structure was elucidated by comprehensive spectroscopic analysis as well as by quantum chemical computation of electronic circular dichroism spectra. Perovskiaol (1) was a novel C22 terpenoid containing a unique D‐ring simultaneously fused with rings A, B, and C, and encountered in nature for the...
