title: Sterols of male and female compound inflorescences of Zea mays L.
abstract: A comparison has been made between the sterols of male and female inflorescences and of pollen from Zea mays. The female inflorescence was shown to contain cholesterol, 24-methylcholesterol, 24-ethyl-5,22-cholestadien-3β-ol, 24-ethylcholesterol and (28Z)-24-ethylidenecholesterol. Themale inflorescence contained the same five compounds together with 24-methylenecholesterol. Pollen contained 24-methylenecholesterol as its main sterol together with lesser amounts of cholesterol, 24-ethylcholesterol, (28Z)-24-ethylidenecholesterol, 24-methylene-5α-cholest-7-en-3β-ol and 4α-methyl-24-methylene-5α-cholest-7-en-3β-ol.
