| Summary: | © 2015 Sociedade Brasileira de Farmacognosia. Published by Elsevier Editora Ltda. All rights reserved. Chemical investigation of Cycas vespertilio A. Lindstr. & K.D. Hill, Cycadaceae, a plant endemic to the Philippines, yielded pinoresinol (1), sesamin (2), paulownin (3), a mixture of β-sitosterol and stigmasterol, and triacylglycerols from the cone base; 1, 3, β-sitosterol, stigmasterol, triacylglycerols, and lariciresinol (4) from the cataphylls; β-sitosterol from the megasporophyll lamina; β-sitosterol and a mixture of trans-4-hydroxycinnamate fatty acid esters (5) and cis-4-hydroxycinnamate fatty acid esters (6) from the unripe sarcotesta; and β -sitosterol and triacylglycerols from the ripe sarcotesta. The structures 1–6 were elucidated by extensive 1D and 2D NMR spectroscopy. |
