Two new nonacosanetriols from the pollen of Typha angustifolia

Abstract Chemical investigation of the pollen of Typha angustifolia Linn. has led to the isolation of two new nonacosanetriols, 7,8,10-nonacosanetriol ( 1 ) and 7,9,10-nonacosanetriol ( 2 ). Their structures were elucidated by chemical reaction and spectral analysis. Compounds 1 and 2 exhibited weak activity of antiplatelet aggregation in vitro .
