On the basis of a preliminary u.v. assay of the dried leaf of nine species of Beilschmiedia and 26 species of Endiandra, several were selected for closer examination.Magnolol (9) was found in B. volckii and (+)-sesamin (10) was isolated from E. xanthocarpa.Endiandric acid B (2) and endiandric acid C (3) were obtained from both E. jonesii and B. tooram, and endiandric acid A (1) was found in B. obtusifolia.The new endiandric acid derivative (1'RS,3'RS,6'SR,7'SR,10'SR,11'RS,12'RS,13'RS)-2-3,13.010,12>trideca-4',8'-dien-11'-yl>acetic acid (3'',4''-methylenedioxyendiandric acid A) (4) was extracted from B. oligandra which also yielded the new phenolic benzopyran derivative (-)-(E)-2-(4',8'-dimethylnona-3',7'-dienyl)-2,8-dimethyl-3,4-dihydro-2H-1-benzopyran-6-ol (oligandrol) (12a).Several known hydrocarbon derivatives and terpenoids were isolated from from the leaf of E. palmerstonii and E. bailonii, both of which were devoid of endiandric acids.

X-ray crystallographic analysis shows that endiandric acid and a derived lactone have the respective structures 2-(6'-phenyltetracyclo3,13,010,12>trideca-4',8'-dien-11'-yl)acetic acid and 12-phenyl-3-oxapentacyclo7,5,2,0sup

X-Ray crystal structure analysis shows that endiandric acid, a constituent of the Australian tree Endiandra introrsa, has the novel racemic structure (1), (1RS,3RS,6SR,7SR,10SR,11RS,12RS,13RS)-(6-phenyl-tetracyclo3,13010,12>trideca-4,8-dien-11-yl>acetic acid.
