Three picrotoxane sesquiterpenes including one new glycoside and two known constituents, sapidolide A (2) and picrotoximaesin (3), were isolated from the berries of Baccaurea ramiflora. The structure of the new sesquiterpene glycoside, ramifloside (1), was elucidated as 2-one-6α-hydroxy-13-nor-11-picrotoxen-3(15β)-olide 10-O-β-D-glucopyranoside on the basis of extensive spectroscopic analysis. Compounds 1-3 exhibited antifungal activity against Colletotrichum gloeosporioides with MICs of 12.5, 12.5 and 50 μg/mL.

has an unstable ripening period. Herein, five typical periods of fruit ripening of 'LR' were analyzed by non-targeted metabolomics techniques. The results showed that ripening started 73 days after flowering and reached the ripening criterion at 93 days, a total of 451 differential metabolites were identified for the five periods.
