Publication date: September 2017 Source:Phytochemistry Letters, Volume 21 Author(s): Zhenggang Yue, Pei Xie, Hui Qin, Yalei Pan, Xiupeng Zhang, Mingfei Zhang, Xiaomei Song, Feng Feng, Zhishu Tang, Jinao Duan As part of our ongoing research in medicinal herbs of Qinba Mountains in China, the plant Jasminum giraldii was chemically investigated. Four new phenylpropanoid glycosides, 9-O-(E-cinnamoyl)-coniferin (1), 6′-O-(E-cinnamoyl)-coniferin (2), 6′-O-(E-cinnamoyl)-syringin (3) and 2′-O-(E-cinnamoyl)-syringin (4), together with two known phenylpropanoid glucosides, coniferin (5) and ethylsyringin (6) were obtained from the roots of Jasminum girialdii. The structures of these compounds have been characterized according to spectral evidences and named on basis of their biosynthetic pathway. In addition, in vitro cytotoxic activities of these compounds were evaluated, however, none of these compounds showed cytotoxicity. Graphical abstract
