Eleven previously undescribed sesquiterpenoids, arvestolides D–J, arvestonates A–C, and arvestonol were isolated from the aerial parts of Artemisia vestita W. Their structures were elucidated by extensive analysis of HRMS, UV, IR, and NMR spectroscopic data, and the absolute configurations were determined by single crystal X-ray diffraction, empirical rules, and comparison of calculated and experimental...
Nine non-phenolic compounds, including four furanylmethyl glycosides, angularides A–D, one ent-kaurane diterpene glycoside, angularin A, and four triterpenoid saponins, angulasaponins A–D, were isolated from seeds of Vigna angularis, together with eight known compounds. Their structures were elucidated on the basis of extensive 1D and 2D NMR spectroscopic analysis as well as chemical methods. Angularin...
