Three known dammaranes, cabraleone, eichlerianic acid and shoreic acid, tog
ether with two new ones, aglinins A and B, were isolated from the bark of A
glaia lawii. A. tomentosa also contained dammarane triterpenes: the known,
cabraleone, cabraleadiol 3-acetate, 3-epiocotillol, cabralealactone, cabral
ealactone 3-acetate and the new aglinins C and D. In addition, two new preg
nane steroids, aglatomins A and B, were isolated from A. tomentosa along wi
th the known cytotoxic cyclopentatetrahydrobenzofuran, rocaglaol. The struc
ture of the new compounds was determined by spectral means, essentially 2D
NMR experiments. (C) 1999 Elsevier Science Ltd. All rights reserved.
