Abstract: The fruit of Camptotheca acuminate is used as a traditional Chinese medicine. Eight compounds were isolated from the fruit of
Camptotheca acuminate for the first time, including (+)-(S)-abscisic acid (1), blumenol A (2), (E)-3-hydroxymegastigm-7-en-9-
one (3), (-)-(3R)-3,5-dimethyl-8-methoxy-3,4-dihydroisocoumarin (4), (-)-(3R)-8-methoxy-3-methyl-3,4-dihydro-1H-isochromen-
1-one (5), neocnidilide (6), (3S)-butylphthalide (7) and senkyunolide I (8). Their structures were determined by comprehensive
spectroscopic methods, including HRESIMS and 1D NMR.

Key words: Camptotheca acuminate, separation and purification, structure elucidation
