Saxifraga umbellulata grows mainly in high, cold areas such as southwest of China and Qinghai and Gansu Provinces [1]. S. umbellulata is an important herbal medicine, which has been used as a traditional folk medicine for the treatment of hepatitis, cholecystitis, infuenza, fever, sore, and so on [2]. As part of our continuous research on S. umbellulata, five compounds were isolated from S. umbellulata for the first time. The air-dried whole plants of S. umbellulata were bought from Kumbum Monas...

The genus Celastrus belongs to the family Celastraceae, comprising 50 species, of which 30 species are distributed in China [1]. Celastrus monospermus Roxb is a liana plant belonging to the Celastraceae family and is widely distributed in Guizhou, Guangdong, Hainan, Guangxi, and Yunnan Provinces of China. It grows at 300–1500 m above sea level [2]. Previous chemical studies led to the isolation of triterpenens with the friedelane skeleton, which exhibited diverse activities in rheumatism, leukem...

There are about 240 species of the Gentiana genus grown in China, Gentiana algida Pall. is broadly distributed in the alpine zone of the world. In China, it is a little-investigated medicinal plant, that grows mainly in high cold areas such as Tibet, Sichuan, Xinjiang, Qinghai, and Jilin Provinces [1]. To the best of our knowledge, no work has been reported on the chemical constituents of Gentiana algida. As part of our continuing research on Gentiana algida Pall. [2], we have isolated six compo...

A new hopane type pentacyclic triterpenoid, 2-hydroxydiplopterol (1) has been isolated from the metabolites produced by the halotolerant fungal strain Aspergillus variecolor B-17. The structure of 1 was determined by spectroscopic methods and single crystal X-Ray diffraction analysis. 2-Hydroxydiplopterol (1) exhibited cytotoxicity against K562 cells with an IC50 value of 22 µM.
