Chemical constituents of cycas lacrimans
Chemical investigation of Cycas lacrimans, a plant endemic to the Philippines, led to the isolation of isopimaran-19-ol (1) from the megasporophyll lamina; 9αH-isopimara-7,15-diene (2) and triacylglycerols (3) from the bark; 3, oleic acid (4), and 1,2-dioleylglycerol (5) from the leaflets; 3, β-sito...
