Four new 13,14‐seco‐withanolides, minisecolides A – D (1 – 4), together with three known analogues 5 – 7, were isolated from the whole plants of Physalisminima. The structures of new compounds were determined on the basis of spectroscopic analysis, including 1H‐, 13C‐NMR, 2D‐NMR (HMBC, HSQC, ROESY), and HR‐ESI‐MS. Evaluation of all isolates for their inhibitory effects on nitric oxide (NO) production...
Six new withanolides (1–6), including two uncommon 1,10-seco withanolides (1 and 2), together with five known withanolides (7–11), were isolated from the whole plants of Physalis minima Linn.. The structures of new compounds were elucidated through spectroscopic methods, including 1 H, 13 C NMR, 2D-NMR, HRESIMS and circular dichroism (CD). Inhibitory effects of the isolates on nitric...
