title: A new sulphated nor-sesquiterpene from mangrove Laguncularia racemosa (L.) Gaertn. F.
abstract: A new sulphated nor-sesquiterpene, 3alpha-hydroxysulphonyloxy-5alpha,6alpha-epoxy-megastigmen-9-one (1), and a known sulphated lipid, 5'-(hydroxysulphonyloxy) jasmonic acid (2), have been isolated from the twigs and leaves of mangrove Laguncularia racemosa (L.) Gaertn. F. The structure of the new compound was elucidated on the basis of detailed analysis of spectroscopic data and chemical reaction.
