Publication date: June 2018 Source:Biochemical Systematics and Ecology, Volume 78 Author(s): Hui Lv, Chun-Sheng Fu, Hui-Xin Hu, Xiao-Ning Wang, Dong-Mei Ren, Hong-Xiang Lou, Tao Shen Phytochemical investigations of the ethanolic extract from the calyxes of Physalis alkekengi L. var. franchetii (Mast.) Makino led to the isolation of n-heptadecanoic acid (1), n-pentadecanoic acid (2), n-hexadecoic acid (3), n-undecanoic acid (4), hendecane (5), β-sitosterol (6), n-octadecanoic acid (7), isovanillic acid (8), 4-methylgentisic acid (9), 2,3,4-trihydroxybenzoic acid (10), 5,7-di-O-methylquercetin (11), 8-hydroxy-7-methoxycoumarin (12), 4,7-didehydroneophysalin B (13), and (Z)-9,10,11-trihydroxy-12-octadecenoic acid (14). Their structures were established by extensive analysis of their NMR spectroscopic data and comparison with literature data. In the present research, compounds 8 and 11 are reported for the first time in the genus Physalis. Compounds 10 and 12 were firstly isolated from Solanaceae family. Compound 9 was isolated from plants for first time. The chemotaxonomic significance of the isolated compounds has been discussed.
