Extraction and isolation of compounds from chloroform extract of Goniothalamus donnaiensis leaves, Annonaceae

Abstract

Two compounds including a stylryl lactone: goniodiol, and a phytosterol: daucosretol were isolated from the chloroform extract of the leaves of Goniothalamus donnaiensis. Leaves of G. donnaiensis were collected in Vinh Cuu district, Dong Nai province in November 2019. Their chemical structures were elucidated by ESI-mass, 1 H- NMR, 13 C-NMR, DEPT, HSQC and HMBC spectra. These two compounds were first isolated from the leaves of Goniothalamus donnaiensis.
