Aleurites is derived from a Greek word meaning “wheaten flour,” because of the appearance of the under
surface of the leaf. The most widespread species is the Candlenut.
Lumbang is a large tree reaching a diameter of 80 to 150 centimeters. Younger parts and the inflorescences are hairy. Leaves have long petioles. Blades are ovate to lanceolate, 10 to 20 centimeters long, entire or lobed. Flowers are white, numerous, 6 to 8 millimeters long, borne on panicles 10 to 15 centimeters long. Fruit is fleshy, ovoid, smooth, 5 to 6 centimeters long, containing 1 or 2 hard-shelled, oily seeds. Shell of the seed is very hard, rough, ridged, about 2.5 millimeters thick. Within the seed is a white, oily, fleshy kernel consisting of a very thin embryo surrounded by a large endosperm.
– Throughout the Philippines, at low and medium altitudes, in second-growth forests, thickets, etc.
– Occurs in tropical Asia to Polynesia.
– Now planted in most tropical countries.
– Kernel contains 52-60 percent of oil.
– Oil contains an acrid resin, a purgative principle.
– Oil yields essential fatty acids (linoleic and linolenic acids).
– Studies have yielded sterols, flavonoids and triterpenes from the leaves.
– Various extracts and fractions of leaves yielded phenolic compounds, n-hentriacontane, α-amyrin, β-amyrin, stigmasterol, β-sitosterol and campesterol.
– Dichlormethane extract of bark yielded 12-hydroxy-13-methoxy-8,11,13- podocarpatrien-3-one, spruceanol, 3-acetylaleuritolic acid, polyprenols, triglycerides and a mixture of β-sitosterol and stigmasterol in a 4:1 ratio.
– Study yielded a new phorbol diester, 13-O-myristyl-20-O-acetyl-12-deoxyphorbol, from the benzene extract of the heartwood of Aleurites moluccana, together with, hentriacontane, 6,7-dimethoxycoumarin, 5,6,7-trimethoxycoumarin and beta-sitostenone.
– Considered a drying oil, resembling linseed oil and the Chinese wood oil (tung oil).
– Shells are very hard and difficult to crack; likewise, difficult to separate the kernel from the shell.
– Oil has a light yellow color
– Kernels considered aphrodisiac.
– Like castor oil, it has a mild aperient action.

– Dye: In Hawaii, seed husk used to make a black dye for tattooing; the root bark used to make a dye for painting canoes.
– Candle nuts are toxic when eaten raw.
– This blogspot (Candlenut Poison Antidote) offers alternative folkloric antidotes: coconut cream or water, turmeric, grape skin extract pill, almonds, fish oil, among others. Besides sharing these folkloric remedies, the author also shares his experience with candle nut toxicity.
• Flavonoids: Chitin chromatographic separation yielded two flavonoids from AM extract: swertisin and 2″-O-rhamnosylswertisin.
• Anti-Inflammatory / Antipyretic: Study on the methanolic extract of dried leaves of AM significantly prevented an increase in volume of paw edema in a dose-dependent manner. It also caused an antipyretic effect. Results justifies the ethnic uses of the plant.
• Hypolipidemic Activity: Study of the methanol extract of leaves showed a lipid lowering effect mediated through inhibition of hepatic cholesterol biosynthesis and reduction of lipid absorption in the intestine.
• Anti-Termite Activity: Study on the Formosan termite (Coptotermes formosanus) showed that oil-treated wood was resistant to termite damage when the wood contained >27% kukui oil by weight. Results indicate that the oil acted primarily as a feeding deterrent and not as a toxic agent.
• Antinociceptive: Study on a spray dried extract (SDE) of leaves isolated flavonoids swertisin and 2′′-O-rhamnosylswertisin which were effective in inhibiting the hypernociceptive response induced by carrageenan.
• Termite Study: Study on kukul plant oil for termite control properties showed the oil acted primarily as a feeding deterrent and not as a toxic agent.
• Antinociceptive / Phytochemicals: Fractions yielded phenolic compounds, n-hentriacontane, α-amyrin, β-amyrin, stigmasterol, β-sitosterol and campesterol. Compounds inhibited acetic-induced abdominal constrictions, more efficaciously than aspirin and paracetamol. Results showed potent antinociceptive action.
• Flavonoid 2″-O-rhamnosylswertisin / Antinociceptive: Study evaluated a dried extract of A. moluccana and the isolated flavonoid 2″-O-rhamnosylswertsin on different models of long-lasting inflammation and neuropathic pain in mice. Oral treatment with the extract and isolated compound attenuated neutrophil migration and IL-1ß levels following carrageenan injection.
• Podocarpane Trinorditerpenoids / Cytotoxicity: Study of twigs and leaves of Aleurites moluccana yielded three novel 3,4-seco-podocarpane-type trinorditerpenoids, moluccanic acid, moluccanic acid methyl ester, and 6,7-dehydromoluccanic acid. In cytotoxicity studies, 1-3 showed weak activity against Burkitt’s lymphoma cell line, while compound 2 showed moderate cytotoxic activity against HepG2 (hepatocellular carcinoma) human cell line.
• Wound Healing / Bark: Study evaluated the wound healing activity of the bark of Aleurites moluccana in three types of rat models viz. excision, incision, and burn wound model. Results showed remarkable wound healing activity, comparable to standard drug nitrofurazone in terms of wound contracting ability, wound closure time, and tensile strength.
• Antibacterial: Aleurites moluccana extracts have shown inhibitory activity against S. aureus and P. aeruginosa. Study further investigated the antibacterial activity of acetonitrile, extracts of husk, leaf and stem bark against 8 clinical isolates. The antibacterial action was bactericidal for all bacteria except S. pyogenes where it was bacteriostatic. The highest polyphenol content was found in the methanol extract of stem bark.
• Biodiesel: Study investigated the production of methyl ester for use as biodiesel. The biodiesel produced had properties similar to diesel oil except for a higher viscosity. Study concluded that biodiesel production by ethanolysis of candlenut oil can be done under ambient conditions. The biodiesel product has comparable fuel properties with diesel oil and is a suitable alternative to diesel oil.
• Antinociceptive / Anti-Inflammatory / Wound Healing: Study of a semisolid formulation containing 0.5 to 1.0% of saturated dried extract was found effective for topical use in treatment of pain, inflammation, and wound healing.
• α,β-Amyrenone / Anti-Inflammatory / Antihypersensitivity: A mixture of α,β-amyrenone was isolated from a dichlormethane fraction of A. moluccana and evaluated using a carrageenan-induced paw edema or pleurisy and CFA-induced arthritis models in mice. Results showed α,β-amyrenoneinterferes with both acute and chronic inflammatory processes, in part, through a reduction of neutrophil migration. It suggests α,β-amyrenone could be a new therapeutic tool for use in painful and inflammatory diseases.
