Abstract
Background: Sibiraea angustata was used as folk medicine in Tibetan‑inhabited area of Hengduan Mountains, China.Objective: The secondary metabolites from the leaves and twigs of S. angustata were studied.Materials and Methods: The compounds were isolated and purified using silica gel and Sephadex LH‑20 column chromatography. Their structures were identified by spectra analysis.Results: Eight known compounds, including 2 monoterpenoids and 3 triterpenoids, were isolated and identified from S. angustata.Conclusions: Four compounds were isolated from this plant for the first time, and the 13C‑nuclear magnetic resonance spectra data and absolute configuration of dihydroneroloxide were given for the first time.
Keywords: Electronic circular dichroism; monoterpenoids; secondary metabolites; Sibiraea angustata
