title: New phytoconstituents from the stem bark of Tinospora cordifolia Miers.
abstract: 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.
