24β-ethylsterols,n-alkanes and n-alkanols of Clerodendrum splendens

The sterols of Clerodendrum splendens, an angiosperm belonging to the family Verbenaceae, were found to possess a 24β-ethyl group. No other sterols were detected. The major sterol was 24β-ethylcholesta-5,22E,25(27)-trien-3β-ol also known as 25(27)-dehydroporiferasterol]. A very small amount of what may have been its 22-dihydroderivative, clerosterol also known as 25(27)-dehydroclionasterol] was also found. The dominant n-alkane was C₂₉ (n-nonacosane) and the dominant n-alkanol was C₂₈ (n-octacosanol).
