Diospyros blancoi A. DC. - syn. Diospyros discolor Willd.; Diospyros philippensis (Desr.) Gürke - Ebenaceae
mabola tree, velvet apple, velvet persimmon, butter fruit, Mabolo
Evergreen tree, native to Indonesia, Philippines, widely cultivated in tropics; leaves oblong, leathery, up to 20cm long, shiny green above, softly hairy below; female flowers axillary, solitary, larger than male; fruits globose, 8-10cm in diam., fleshy, covered with short brown hairs.
„The fruit flesh is whitish, somewhat hard and dense, somewhat dry, slightly astringent sweet and fragrant… it smells a bit harsh like cheese and durian (for some people sweet, for some even like cat litter).“
„The pulp is edible. The fruit hairs have to be rubbed off before eating as it can cause peri-oral itching and irritation.“ http://www.stuartxchange.com/Mabolo.html
„A petroleum ether extract of the peelings of the fresh fruits of Diospyros discolor Willd. on treatment with ethanol gave an extract in which the following major components were identified: benzyl benzoate(19.2%), benzyl salicylate (26.9%), cinnamyl benzoate (10.3%), benzyl butyrate (4.1%) and butyl benzoate (6.0%). The absence of alkyl butyrates, which were previously reported in the essential oil from this species, may be as the result of their hydrolysis to give free butyric acid. The free acid could be responsible for the change in odor to a harsher butyric note after the fruit has been harvested.“

„The volatile constituents of the fruit of Diospyros blancoi DC. were isolated by vacuum distillation with subsequent extraction of the distillate with dichloromethane. The concentrated extract was analyzed by capillary GC and GC/MS. Sixty-seven components were identified; esters were clearly dominant, accounting for 88.6% of the total volatiles. The major components were methyl butyrate (32.9%), ethyl butyrate (10.7%), butyl butyrate (10.2%) and benzyl butyrate (10.0%). Four of the esters found were sulfur-containing compounds.“

Ninety-six volatile compounds were identified in mabolo fruit, mainly esters like benzyl butyrate (33.9%), butyl butyrate (12.5%) and (E)-cinnamyl butyrate (6.8%).
