摘要：

Twenty-nine free and glucosylated dihydrophenanthrenes and tetrahydropyrenes isolated from Juncus effusus have been tested against the unicellular green alga Selenastrum capricornutum. The free compounds showed a strong inhibitory activity, while the glucosides were inactive or had a slight stimulating effect on growth. Tetrahydropyrene 33, obtained by hydrolysis of the natural beta-glucosides 29 and 30 or by hemisynthesis from 1, is the most active compound, causing 90% inhibition of the growth at 2.5 x 10(-5) M concentration. Synthetic ai-glucosides 28, 31, and 32 showed comparable activity to those of 29 and 30.
