摘要：

Oryzalides A and B, and oryzalic acid A, which were isolated from healthy flag leaves of a bacterial leaf blight-resistant cultivar of rice plant as a group of novel antimicrobial compounds, were confirmed by chemical and spectroscopic studies to be ent-kaurane (C19 and C20) or ent-kaurene (C19) analogues, i.e., oryzalide A, ent-15-alpha,16-epoxy-1-beta-hydroxy-2-oxa-kauran-3-one; B, ent-1-beta,15-alpha-dihydroxy-2-oxa-16-kauren-3-one; and oryzalic acid A, ent-15-alpha,16-epoxy-2,3-secokauran-2,3-dioic acid.
