	abstract = {Epicuticular and intracuticular waxes from both adaxial and abaxial surfaces of the leaves of Kalanchoe daigremontiana were analyzed. All wax mixtures were found to contain approximately equal amounts of triterpenoids and very long chain fatty acid (VLCFA) derivatives. The triterpenoid fraction consisted of glutinol (8-19\% of the total wax) and friedelin (4-9\%), together with smaller amounts of glutanol, glutinol acetate, epifriedelanol, germanicol and beta-amyrin. The VLCFA derivatives comprised C-27-C-35 alkanes (19-37\% of the total wax), C-32-C-34 aldehydes (3-7\%), C-32 and C-34 fatty acids (0.2-3\%), C-26-C-36 primary alcohols (4-8\%), and C-42-C-52 alkyl esters (2-9\%). The wax layers were found to differ in triterpenoid amounts, with the intracuticular wax containing higher percentages of most triterpenoids than the epicuticular wax. Friedelin, the only triterpenoid ketone present, showed the opposite distribution with higher proportions in the epicuticular wax. VLCFA derivatives also accumulated to higher percentages in the epicuticular than in the intracuticular wax layer. Epicuticular wax crystals were observed on both the adaxial and abaxial leaf surfaces. (C) 2009 Elsevier Ltd. All rights reserved.},

	abstract = {The glaciasterols, a family of cytotoxic 9,11-secosteroids, have been isolated from extracts of the northeastern Pacific sponge Aplysilla glacialis. The structures of glaciasterol A (2) and glaciasterol B (3) were elucidated by a combination of spectroscopic analysis and chemical interconversions on the native steroid 2 and the diacetate 5 of glaciasterol B (3).},
