Abstract

From the resinous exudate of Heliotropium huascoense a new compound, rel-(8R,9R)-carrizaloic acid, (1) (3-[rel-(8R,9R-9-hydroxy-9,13,13-trimethyl-12-oxo-10-cyclohexenyl)methyl]-4-methoxybenzoic acid), and three known flavonoids, [3-methylgalangin, 3,7-dimethylgalangin, and (-)-alpinone] have been isolated. The structure of 1 was determined by spectral and chemical methods. Several plant defensive properties of 1 (insecticidal and antifungal) have been evaluated.

摘要

从瓦斯科天芥菜（Heliotropium huascoense）的树脂状渗出物中分离出一种新化合物，反式-(8R,9R)-卡里扎洛酸（1）（3-[反式-(8R,9R-9-羟基-9,13,13-三甲基-12-氧代-10-环己烯基)甲基]-4-甲氧基苯甲酸）以及三种已知的黄酮类化合物[3-甲基高良姜素、3,7-二甲基高良姜素和(-)-阿尔皮酮]。通过光谱和化学方法确定了1的结构。对1的几种植物防御特性（杀虫和抗真菌）进行了评估。
