TL;DR: Phytochemical investigation of the roots of Solanum melongena L resulted in the isolation of ten terpenes and sixteen lignans, including a new triterpene saponin, officinoterpenoside E and twenty-five known compounds, which seemed to be of great chemotaxonomic value for S.melongena.

TL;DR: Two new lignans (1-2) and a new natural product (3), as well as eighteen known compounds (4-21) were isolated from the roots of Datura metel L for the first time as discussed by the authors.

TL;DR: Phytochemical investigation of the roots of Solanum melongena L. resulted in the isolation of six new steroidal saponins, including five new cholestane sapon Ins (1-5), along with one new natural product and three know steroids (8-10).

TL;DR: In this paper, three new lignanamides, melongenamide E-G (1, 3), together with fourteen known analogues (4-17) were isolated by bioassay-guided fractionation from the roots of Solanum melongena L. The chemical structures of all isolated compounds were elucidated using 1D and 2D NMR experiments and by comparing their spectroscopic and physical data with values from the published literature.

TL;DR: Picrorhizae Rhizoma as a hepatoprotective herb, has been applied for thousands of years, and picroside was proved to be its active constituent, and the activity of two derivatives was stronger than that of the reference compound, silybin.
