Lignans and a furanone from Cycas sancti-lasallei
Chemical investigation of the dichloromethane extracts of Cycas sancti-lasallei, a plant endemic to the Philippines, led to the isolation of sesamin (1), 4-hydroxymethyl-3,5-dimethyldihydro-2-furanone (2), squalene, and phytyl fatty acid ester from the petiole and rachis; and 8-hydroxypinoresinol (3...

| Summary: | Chemical investigation of the dichloromethane extracts of Cycas sancti-lasallei, a plant endemic to the Philippines, led to the isolation of sesamin (1), 4-hydroxymethyl-3,5-dimethyldihydro-2-furanone (2), squalene, and phytyl fatty acid ester from the petiole and rachis; and 8-hydroxypinoresinol (3) from the sclerotesta. The structures of 1-3 were elucidated by extensive 1D and 2D NMR spectroscopy. The relative stereochemistry of 3 was determined from NOESY. © 2015, International Journal of Pharmacognosy and Phytochemical Research. All rights reserved. |
