Tree growing to a height of 4 to 20 meters. Leaves are alternate, 20 to 40 cm long, with 5 to 7 leaflets, oblong to oblong-elliptic, pointed at both ends. Flowers are small, yellow and borne on spikes, solitary or fascicled on the trunk or larger branches. Fruit is yellowish-white, occuring in bunches on a single stem, ellipsoid or globose, 2-4 cm long, with bitter seeds that are surrounded by a translucent pulp. The outer skin is thin and tough, abundant in a milky juice. The pulp occurs in five sections with one well-developed seed.
- Cultivated for its fruit.
Chemical constituents and properties
- The rind yields 6% lansium acid which is toxic.
- The fresh peeling yielded a volatile oil, a resin, and some reducing acids.
- The resin is believed to be nontoxic and protective to the stomach against alcohol.
- The outer skin of the fruit is rich in tannin.
From the seeds, two toxic and bitter substances and traces of an alkaloid. The fruit pulp contains sucrose, saccharose, fructose and glucose. Bark is astringent.
- Study isolated a new tetranortriterpenoid (Source)
- Study yielded five tetranoterpenoids, domesticulide A-E (1-5) from the seed. The seed extract was rich in limonoids.
- Triterpenoid lansiolides with antimalarial activity.
- Bark, fruit, leaves, seeds.
The fruit pulp is succulent and delicious, and may be candied or preserved in syrup. Food value per 100 g of edible portion: Moisture 86.5 g; protein 0.8 g; carbohydrates 9.5 g, fiber 2.3 g; calcium 20 mg; phosphorus 30 mg; vitamin A 13 IU; thiamine 89 mcg; riboflavin 124 mcg; ascorbic acid 1 mg.
- Decoction of bark and leaves used for dysentery.
- Peel, rich in oleoresin, used for diarrhea and intestinal spasms.
- Crushed seeds used for fevers.
- Astringent bark used for dysentery and malaria.
- Powdered bark used for scorpion stings.
- Bark resin used for flatulence and gastrointestinal colic, for swellings, and as antispasmodic.
- Grounded seeds mixed with water as vermifuge and antipyretic.
- Tincture prepared from the dried rind used for diarrhea and abdominal colic.
- In Indonesia, used for malaria
- Cosmeceutical value from its antioxidant, moisturizing, whitening and lightening effects. Dry extract of fruit, re-dissolved in propylene glycol is used for skin depigmentation and as a moisturizer.
- The dried fruit skins when burned emit an aromatic smell which repels mosquitoes. It also makes a pleasant room inhalant.
- The juice of the bark and fruit is recorded as used for poison arrow.
- Anti-Malarial: (1) Lansium domesticum: skin and leaf extracts of this fruit tree interrupt the lifecycle of Plasmodium falciparum, and are active towards a chloroquine-resistant strain of the parasite (T9) in vitro: Study indicates extracts of LD are a potential source for compounds with activity against chloroquine-resistant strains of P. falcifarum. (2) Study yielded firve tetratriterpenoids – domesticulide A-E from the seeds of Lansium domesticum together with 11 known triterpenoids. Eight of the compounds showed antimalarial activity against Plasmodium falcifarum.
- Antioxidant: Extract of LD has shown to have antioxidant activity against DPPH free radical and anti-tyrosinase activity.
- Skin Moisturizing / Lightening Effect: Study showed LD extract can significantly increase skin moisture and decrease the skin melanin index.
- Antimelanogenesis: LD methanol extract was one of the study extracts that showed strong inhibition of melanin production of B16 melanoma cells without sginificant cytotoxicity, presenting as a potential ingredient for skin-whitening cosmetics if their safety can be confirmed.
- Antibacterial: The air-dried fruit peel of LD yielded five onoceroid triterpenes; the air-dried seeds yielded one onoceroid triterpene (lansionic acid) and germacrene D. Studies of the compounds showed varying degrees of activity against P. aeruginosa, B subtilis, C albicans, A niger among others.
- Anti-Skin Tumor: Study isolated a new cycloartanoid triterpene from the leaves of LD. Some of the natural product derivaties show significant inhibitory activity on skin-tumor promotion on the basis of Epstein Barr virus activation.
- Onoceramoid Triterpenes / Cytotoxicity: Study isolated three new natural onoceranoid triterpenes from the fruit peel of LD together with two known triterpenoids. The triterpenoids exhibited mild toxicity against brine shrimp (Artemia salina).
