Abstract
A new ester compound, ethyl-(9E)-8,11,12-trihydroxyoctadecenoat (1), and five known compounds comprising a mixture of 3-hydroxy-3-methyl-5-hexanolide (2A) and leucine (2B), indole-3-aldehyde (3), 3β,7α-dihydroxy-6-cholest-5-ene (4), cholest-5-ene-3β,7β-diol (5), and saringosterol (6) were isolated from the dichloromethane extract of male Carica papaya flowers. Their structures were determined by NMR, MS spectra and comparison with the reported data.
