The tree grows up to 40 metres (130 ft) tall with a trunk diameter of up to 40 centimetres (16 in). The bark is dark grey to chocolate brown. The flowers are creamy-white. The fruits are round, yellow (blood-red when ripe), up to 6 cm (2 in) in diameter.[5]
Eight previously unknown limonoids were identified via spectroscopy in the fruits of C. erythrocarpus gathered in Malaysia. These compounds were dubbed erythrocarpines after the species epithet.
The same study tested several preparations of C. erythrocarpus extract as larvicidal agent against Aedes aegypti mosquitoes; they found that 1000 ppm DCM extract resulted in 100% mortality of larva 24 hours after exposure.[6]
