title: New 3,4-seco-cycloartane triterpenes from Gardenia sootepensis.
abstract: Two new 3,4-seco-cycloartane triterpenes, named sootepins H (1) and I (2), were isolated from the ethyl acetate extract of the leaves and twigs of Gardenia sootepensis. Their structures were elucidated on the basis of 1D- and 2D-nuclear magnetic resonance (NMR) analysis, as well as high-resolution mass spectrometry (HR-MS), infrared (IR), and ultra violet (UV).
