Isopyrodysinoic acid (2), 13-hydroxyisopyrodysinoic acid (3), and pyrodysinoic acid B (4) were obtained from the crude extract of D. robusta and identified by analysis of spectroscopic data. Pyrodysinoic acid B (4) is the first furodysin or furodysinin sesquiterpene derivative with a trans junction between the two six-membered rings of the 1,2,3,4,4a,7,8,8a-octahydro-1,1,6-trimethylnaphthalene moiety.}, keywords = {AMINO-ACID, biosynthesis, CELLULAR-ORIGIN, DENDROLASIN, DYSIHERBAINE, GENUS DYSIDEA, HERBACEA, METABOLITES, NATURAL-PRODUCTS, SESQUITERPENES}, isbn = {0163-3864}, url = {://000270855600026}, author = {Williams, D.
