Linamarin, lotaustralin, linustatin, and neolinustatin were isolated from Passiflora pendens (subgenus Plectostemma, section Cieca). Linamarin and lotaustralin were isolated from P. adenopoda (subgenus Plectostemma section Pseudodysosmia), and linamarin (possibly accompanied by linustatin) was isolated from P. warmingii (section Cieca). These data suggest that several members of the subgenus Plectostemma of Passiflora are capable of elaborating valine/isoleucine-derived cyanogenic glycosides instead of or in addition to those which contain cyclopentenoid structures.
