    Author: Suthiphasilp V, Maneerat W, Andersen RJ, Phukhatmuen P, Pyne SG, Laphookhieo S.
    Journal: J Nat Prod; 2019 Nov 22; 82(11):3176-3180. PubMed ID: 31661271.
    Abstract:
    Five new aristolactam alkaloids (1-5), dasymaschalolactams A-E, and the first isolation of dasymaschalolactone (17) as a natural product, together with 19 known compounds (6-16 and 18-25) were isolated from the twig extract of Dasymaschalon dasymaschalum. Their structures were elucidated by spectroscopic methods as well as comparisons made from the literature. Compounds 20 and 21 showed α-glucosidase inhibitory activities with IC50 values of 4.5 and 24.7 μM, respectively.
