摘要：

Lunularic acid and hydrangeic acid have been shown to bind with moderate affinity to the receptor for 1-N-naphthylphthalamic acid in maize coleoptiles and zucchini hypocotyls. While they can inhibit auxin egress from membrane vesicles, unlike non-phenolic phytotropins, they do not prevent the gravitropic response. Analogues of lunularic acid with the carboxylic acid function in the meta position had identical binding, while the carboxyl in the para position decreased binding.
