Only traces of sugar were obtained. The esterified lipids were similar in chain length to capric and lauric acids. The two prinicpal phenolic compounds have UV absorption peaks, and bathochromic shifts on ionization with NaOH similar to those of esters of caffeic acid. On acid hydrolysis, caffeic acid was obtained from these and from three minor phenolic compounds. From two of the minor phenolic compounds, glucose was released by hydrolysis. The phenolic content of stigmas increased up to 20–24 hr before anthesis, and then gradually decreased. Neither compatible nor incompatible pollination affects the amount or composition of the stigmatic exudate. Citing Literature Volume58, Issue4April 1971Pages 317-322 RelatedInformation
