Fifteen diterpene derivatives including seven new ones, sinensisins A− G (1, 2, 4, 7, 10, 14,
15), were obtained from the leaves and twigs of Aphanamixis sinensis. Their structures were …

Four novel indane derivatives, anisotindans A–D (1–4), were isolated from the roots of
Anisodus tanguticus. Their structures were established using comprehensive spectroscopic …

Two new quinolizidine-based alkaloids (2 and 12), along with ten known ones (1, 3–11)
