Chemical Constituents of Pileostegia viburnoides var. glabrescens

Pileostegia viburnoides var. glabrescens (Saxifragaceae) grows in valleys, near streams and rocks and is widely distributed throughout southwest China, India, Vietnam and the Ryukyu islands [1]. It is used to eliminate dampness and stasis as well as stop pain in TCM for the treatment of traumatic injury, fractures, multiple abscess, rheumatism and joint soreness [1–2]. Few phytochemistry studies have been carried out on this plant. In our ongoing chemistry research of this species, five compounds, namely, friedelin, β-sitosterol, umbelliferone, daucostero and skimmin were isolated from Pileostegia viburnoides var. glabrescens for the first time.
