Isol. from Citrus aurantium, Feronia elephantum, Aegle marmelos, Libanotis intermedia and others. Prisms (EtOH). Mp 68°. 

The proposed struct, (illus.) has been synthesised and was not identical with Feronolide. Currently the struct, of Feronolide is unknown. Isol. from cortex of Feronia elephantum. Cryst. (EtOH). Mp 115°. Mp. given refers to natural Feronolide. Synthetic compd. had Mp 66.5-68.5° (2,4-dinitrophenylhydrazone Mp. 61-63°). 

Ketha gum, which exudes from the bark of Feronia elephantum (Rutaceae, Rutales) is reported to have properties similar to those of the Acacia gums (159). The polypeptide portion of a gum from trees of Azadirachta spp. (Meliaceae) has been examined (9). Neem gum Azadirachta indica) (159) contains 35% protein (13).
