Diterpenoids from Baccharis lejía
Phytochemistry(1991)
摘要
Seven new neoclerodanes have been isolated from aerial parts of Baccharis lejía. Four are dimeric diterpenoids linked via a C-18 malonate ester. Relevant toxicity toward Artemia salina (brine shrimp bioassay) was observed only with neoclerodanes bearing a free hydroxyl group at C-18.
