title: Constituents of the pollen of Crocus sativus L. and their tyrosinase inhibitory activity.
abstract: Five new naturally occurring monoterpenoids, crocusatins-A (1), -B (2a), -C (3), -D (4a) -E (5), a new lactate, sodium (2S)-(O-hydroxyphenyl)lactate (6), and eighteen known compounds were isolated and characterized from the pollen of Crocus sativus L. The tyrosinase inhibitory activities of these compounds were also discussed.
