Sesquiterpenes from the aerial parts of Artemisia vachanica krasch. ex poljakov and their anti-inflammatory and anti-diabetic activities.

Eleven undescribed sesquiterpenes, vachanins A-K covering types of germacrane, eudesmane, guaiacane, and cadinane, along with fifteen known analogs were isolated from the aerial parts of Artemisia vachanica Krasch. ex Poljakov. Their structures were established on the basis of HRMS and NMR data, and their absolute configurations were successfully determined by single-crystal X-ray diffraction analysis, C-NMR calculations and DP4+ probability analysis, and ECD data in corporation with quantum chemical calculations.

New Triterpenoids from the Fruiting Bodies of and Their Anti-Inflammatory Activity.

is a popular medicinal mushroom with diverse pharmacological activities in many Asian countries. Four new triterpenoids, named sulphurenoids A-D (-), along with 12 known analogues, were isolated from the fruits of . Nuclear magnetic resonance, infrared spectroscopy, and high-resolution electrospray ionization mass spectrometry (HR-ESI-MS) techniques were used for the investigation of the chemical structure of isolated compounds.
