General info
- Artocarpus is a genus of some 60 trees of Southeast Asian origin, belong to the family Moraceae. The word Artocarpus is derived from the Greek words artos (bread) and karpos (fruit).
- It is said Antipolo City, the capital of Rizal, derived its name from the Antipolo tree, at a time when the tree grew in abundance locally.

Antipolo is a large tree, growing up to 30 meters tall. Its habit, size, and leaf characteristics are similar to Artocarpus altilis (Rimas). Leaves are simple, spirally arranged, with one to three pairs of lobes. Hairy petioles are about 8 centimeters long. Hairy stipules are about 10 centimeters long. Male inflorescence is smooth and cylindric, 5 to 8 centimeters long, flexuous, with spine-like structures. Fruit is ellipsoid, 10 centimeters long, 7 centimeters in diameter, ripening to yellow and orange-brown. Anthocarps are extended into 1-centimeter long, spiculate appendages. Seeds are ellipsoid, about 1 centimeter long, embedded in the fleshy part of the flesh.

- Endemic species.
- Found throughout the Philippines, in thickets and forests, at low and medium altitudes.

Bark extract considered antimicrobial.

Parts utilized
Bark, roots.

- Leaves reportedly used as food by the Ayta people in Porac, Pampanga. (1)
- Fruits and seeds are cooked and eaten.
- Decoction of the two-parts bark of antipolo and one-part roots of Fleurya interrupta (Lipang aso) is used for strangularia.

- Wood: Used for carving and light construction.
Used as fiber plant for making pulp and paper. (4)
- Rope: Bast makes a weak rope, used for yoking buffaloes.
- Repellent: Ayta people burn dry leaves to repel mosquitoes. (2)
- Hunter's sap: Sticky sap from Tipolo placed on tall trees to capture to capture small birds. (6)

Study evaluated 848 solvent extracts from 106 species of Philippine plants belong to 44 families for antimicrobial activity. Of the plants, 62 to 58 percent yielded constituents with inhibitory activity to B. subtilis, M. aureus, E. coli and Mycobacterium tuberculosis. Artocarpus blancoi was one of the 9 most active plants which demonstrated exceptionally high values of antimicrobial activity. (5)
Gum / Drug Suspending Agent: Study evaluated gummy exudates obtained from incised bark of antipolo tree for potential pharmaceutical use as suspending agent. Physiochemical properties of crude gum suspension i.e. pH, viscosity, redispersibility time, sedimentation volume and degree of flocculation, were statistically comparable to standard acacia gum suspension. Results suggest the crude extract is a suitable alternative to imported acacia gum as suspending agent. (6)
