Chemical Constituents of Armadillidium vulgare

Objective: To study the chemical constituents of Armadillidium vulgare. Methods: Compounds were isolated and purified by various column chromatography,spectroscopic methods were used to identify their structures. Results: Seven compounds were isolated from Armadillidium vulgare and identified as vulgarine A( 1),o-hydroxylbenzoic acid( 2),dipyrrolopiperazine-2,5-dione( 3),4( 1-H)-quinolone( 4),adenine( 5),n-acetyltyramine( 6) and 4-methyl-5-thiazoleethanol( 7). Conclusion: Compound 1 is a new alkaloid,compounds 3 ~ 7 are all nitrogen containing substances,which are isolated from Armadillidae family for the first time.
