Six new withanolides, angulasteroidins A−F (1–6), along with twelve known analogs (7‐18) were isolated from the whole plants of Physalis angulata. Their structures were elucidated by analysis of 1D and 2D NMR, ECD and IR spectra, HR‐ESI‐MS data, and ECD calculation. Compounds 1 and 6 were rare 1–10 seco withanolides. Compounds 2–4, 7–9, and 15 exhibited significant inhibitory activity on the production...
Taiwania cryptomerioides Hayata is an endangered relict plant belonging to Taxodiaceae, and it is also an endemic plant to China. The decay‐resistant of Taiwania timber can provide highly quality wood for building and furniture. Plenty of regenerative of leaves of T. cryptomerioides also has been used as a resource for the discovery of new dimeric diterpenoids. In a search for structurally diverse...
