-"It was introduced to Japan in the 19th century but was not accepted and developed as a commercial fruit-bearing tree. One reason is that the fruit had much too strong flavor for Japanese tastes...

-Volatile components of pawpaw (Asimina triloba Dunal.) fruit were mainly ethyl esters (hexanoate, 50.2%; octanoate, 19.3%; butanoate, 8.5%; and decanoate, 1.3%) which were accompanied by methyl esters (butanoate, hexanoate, octanoate, geranate, decanoate, and farnesate). Butane-2,3-diol monoesters (butanoate, hexanoate, and octanoate) and 3-hydroxybutan-2-one (acetoin) esters (acetate, butanoate, hexanoate, and octanoate) were also detected, and these esters except 3-acetoxybutan-2-one were reported to be present in nature for the first time."\\+Volatile components of pawpaw fruit were mainly ethyl esters (hexanoate, 50.2%; octanoate, 19.3%; butanoate, 8.5%; and decanoate, 1.3%) which were accompanied by methyl esters (butanoate, hexanoate, octanoate, geranate, decanoate, and farnesate).

 "The odors of A. triloba and baker’s yeast Saccharomyces cerevisiae shared ethanol, ethyl acetate, acetic acid, and other compounds but differed in relative amounts of 3-methyl-1-butanol, 3-OH-2-butanone, and butane-2,3-diol. Immature green flowers of A. triloba produced sesquiterpenes common to the foliage of many plants. In contrast, sexually mature flowers emitted fermentation volatiles, with additional nitrogenous compounds (androgynoecium) and butanediols (outer corolla) emitted by male flowers... Emission rates were fourfold greater in male than female flowers during the day but were comparable at night, perhaps because of overlapping gender expression. The yeasty odor of A.triloba is unusual in angiosperms and may serve to attract novel fly and beetle pollinators... \\ "The odors of A. triloba and baker’s yeast Saccharomyces cerevisiae shared ethanol, ethyl acetate, acetic acid, and other compounds but differed in relative amounts of 3-methyl-1-butanol, 3-OH-2-butanone, and butane-2,3-diol.

-The floral scent of green, immature flowers of A.triloba was dominated by g-terpinene (11.7%) and E-b-caryophyllene (49.5%), female-stage flowers produced distinctive fermentation volatiles (e.g., ethyl acetate, ethanol, acetic acid) and were dominated by 3-OH-2-butanone (also known as acetoin), which contributed 77.9% of the relative peak area...Female- and male-stage flowers emitted the same absolute amounts of acetoin (not shown), but this compound’s relative contribution to male-stage odor (58.4%) was diminished by the addition of the butanediols and nitrogenous compounds." \\+The floral scent of green, immature flowers of A.triloba was dominated by γ-terpinene (11.7%) and (E)-β-caryophyllene (49.5%), female-stage flowers produced distinctive fermentation volatiles (e.g., ethyl acetate, ethanol, acetic acid) and were dominated by 3-OH-2-butanone (also known as acetoin), which contributed 77.9% of the relative peak area...Female- and male-stage flowers emitted the same absolute amounts of acetoin (not shown), but this compound’s relative contribution to male-stage odor (58.4%) was diminished by the addition of the butanediols and nitrogenous compounds." \\
 Nitrogen compounds of the male-stage odor included 2-methyl butane nitrile, 3-methyl butane nitrile, nitro-2-methyl butane, nitro-3-methyl butane, 2-methyl butyraldoxime, and 3-methyl butyraldoxime. \\ Nitrogen compounds of the male-stage odor included 2-methyl butane nitrile, 3-methyl butane nitrile, nitro-2-methyl butane, nitro-3-methyl butane, 2-methyl butyraldoxime, and 3-methyl butyraldoxime. \\
