Caimito is a tree with a spreading
crown, growing to a height of 15 meters. Branches are numerous and slender, the
young tips are copper-colored and covered with appressed hairs. Leaves are leathery,
ovate or oblong, 7.5 to 13 centimeters long, pointed at the tip, blunt or rounded at the base and covered underneath with silky,

translucent whitish or purplish, soft pulp surrounding flattened seeds about
1 to 1.5 centimeters long. The flesh, contains a small amount of milky juice, is somewhat fibrous, sweet, mild and pleasant tasting.

0.19%; pouterin, 0.0037%; a bitter principle (lucumin), 1.2%; a fixed oil, 6.6%; and dextrose, 2.4%.
- Leaves contain an amorphous bitter principle, some alkaloids, and no
- Bark is rich in tannin.
- Analysis for volatile constituents yielded 104 compounds in the aroma concentrate. Major constituents were: (E)-2-hexenal, 1-hexanol, limonene, linalool, α-copaene and hexadecanoic acid. (8)
- Seed is tonic, diuretic and febrifuge.
- Pectoral, tonic, stimulant.
Seeds, leaves, bark, fruit.

• Cubans in Miami reported to use
the leaf decoction for cancer treatment.
• In Brazil, bark latex used resolutive on abscesses;

• Polyphenolic Antioxidants:
Polyphenolic Antioxidants from the Fruits of Chrysophyllum cainito:
A study on fruit extracts yielded nine known phenolic antioxidants. (2)
• Anthocyanin Antiioxidant: Study of extracts of 12 edible fruits showed nine to exhibit
high antioxidant activity; C cainito yielded cyanidin-3-O-ß-glucopyranoside,
an anthocyanin antioxidant. (3)
• Vasorelaxant: A preliminary
study on the relaxant effect of the crude extract and fractions of the
bark of Chrysophyllum cainito L. in isolated rat thoracic aorta:
Methanolic bark extract study on rats showed vasorelaxant activity on
the smooth muscle. (5)
• Lectin Activity: Plant
samples of 178 species and 62 families were studied for lectin activity.
Potent lectins possessing more than 100,000 unites per gram were found
in the fruits extracts of C arabica and Chrysophyllum cainito. (4)
• Antidiabetic Activity / Leaves: Study of the aqueous decoction of C cainito leaves showed hypoglycemic activity at doses of ≥ 20 g/l. From 30 g/l, the plant would exert a toxic effect. The hypoglycemic effect was mainly attributed to alkaloids, sterols, or triterpenes. (6)
• Hypotensive Effect: Phytochemical study attributes the hypotensive effect flavonoids with vasodilation effect and inhibition of adrenergic receptors. (7)
• Glue Effect: Study explored the potential of star apple extract as glue. Results showed the glue from the star apple extract can be used as a substitute for commercial glue. (12)
