New phytoconstituents from the stem bark of Tinospora cordifolia Miers.
The phytochemical investigation of the stem bark of Tinospora cordifolia Miers (Menispermaceae) has afforded four new compounds, named tinosporafuranol, tinosporafurandiol, tinosporaclerodanol, and tinosporaclerodanoid, along with beta-sitosterol, and their stereostructures have been elucidated correspondingly as 4-seco-cleroda-19-ol-13-furanoid, 4-seco-cleroda-6-en-18,19-diol-13-furanoid, cleroda-1(10)-en-6beta-ol and cleroda-1-one-2-en-11beta,15,16,18-tetraol-12,19-olide on the basis of spectral data analyses and chemical reactions.
