Naturally Occurring Oxygen Heterocyclics. II.¹ Characterization of an Insecticidal Principle from Mammea americana L.²

Acromyrmex octospinosus (Hymenoptera: Formicidae) management. Part 1: Effects of TRAMIL's insecticidal plant extracts

“…The present results were consistent with previous studies revealing that Mammea americana seeds contained insecticidal compounds, e.g. coumarins such as mammein 28–30. The extracts and compounds obtained from the seed of this plant have proved to be insecticidal and larvicidal 31, 32.…”

Constituents of Mammea Americana L. VIII: Novel Structural Variations on the Mammein Theme and Antitumor Activity of Mammein and Related Coumarin and Phloroglucinol Derivatives

“…130-131 O , was encountered. It showed IR and UV spectral properties similar to other phenolic Mammea coumarins bearing the acyl substituent at C-8 (8)(9)(10). Microanalytical data accorded with the formula CZ2HP8O6, and this was verified by the observation of a parent peak in its mass spectrum at m/e 388.…”

“…The extensive efforts of Djerassi and his collaborators (1,8,9), which culminated in Structure I for mammein and revealed in detail the variegated chemistry of this polyfunctional molecule, established a precedent which greatly facilitated access to Structures I1 for mammeisin (2) and I11 for mammeigin (3). Thus, Structure I1 was secured relatively quickly on the basis of experiments conducted in the mammein mold, while Structure 111, although based principally on its NMR spectrum, was easily verified by a chemical interconversion whh 11.…”

Constitution of Mamey Wax

“…Several studies of this property of mamey seed extracts (2-5) led eventually to the isolation (6) of a crystalline active principle. Degradative and spectroscopic (7,8) as well as synthetic evidence (9) was adduced (8) in support of I for this substance which was named mamrnein (7). Subsequently, a yellow toxic (10) compound was isolated from the fruit peelings and shown (11) t o possess 11.…”

“…76.577"; literatures m.p.77.5' (39).No absorption was observed in the NMR spectrum at lower field than the triplet (J = 6 cps.) at 6.367 indicating the absence of vinyl protons. The mass spectral measurements were carried out on two samples, one with m.p.…”
