Withanolides with phytotoxic activity from two species of the genus salpichroa: S. origanifolia and s. tristis var. lehmannii
Seven new withanolides, salpichrolides O-U (1-7), the known 2,3-dihydrosalpichrolide B (9), a substance not previously isolated from a natural source, and three known compounds, salpichrolide D (8), salpichrolide A (10), and salpichrolide C (11), were isolated and characterized from the aerial parts...
