Botany
Utong is a coarse and branched half-woody plant, prickly or unarmed, growing to a height of 0.4 to 1 meter. Stems are prickly and covered with soft short hairs. Leaves are ovate to oblong-ovate, broad as they are long, 10 to 25 centimeters long, armed on both surfaces with long, stout spines, stellate-hairy beneath, and irregularly and shallowly lobed at the margin. Inflorescences are umbelliform and lateral, with 1 to 6 flowers. Flowers are axillary, about 2.5 centimeters long, purplish or bluish. Fruit is fleshy, smooth, purple when ripe, up to 25 centimeters long, extremely variable in shape, rounded, oblong, or cylindric-oblong. Seeds are compressed, purple-brown, 2-4 millimeters in diameter. Fruit flesh is white.

Distribution
- In thickets and waste places along the roads at low altitudes in Leyte; Zamboanga, Mindanao, and Jolo.
- Cultivated in some gardens in Manila and neighboring towns as a curiosity because of the shape of the fruit.
- Introduced from tropical America.
- Propagated by seeds.

Constituents
- Fruit contains trigonelline, choline, vitamins A, B, and C; fat 0.1 percent, and protein 2.2 percent.
- Fruit considered toxic, containing solanine saponin, mallic and gallic acids.
- Fruit yields a glycoalkaloid, solamargine.

- Nutrient analysis per 1 cup/100 g fruit yielded: protein 0.96 g, total dietary fiber 0.78 g, total sugars 3.23 g, calcium 7 mg,
vitamin C 0.05 mg, and 4 ug of beta-carotene.


Properties
- Fruit considered purgative, phlegmatic, generative.
- Leaves are anodyne, narcotic.
- Studies have suggested repellent, insecticide, antiproliferative, antioxidant, antimalarial, molluscicidal properties.


Parts used
Roots, leaves, fruits.

Uses
Nutrition
- Fruit makes an excellent vegetable, the elongated kind is most cultivated, eaten before it ripens, before the seed hardens.
- Good source of calcium, phosphorus, iron, and vitamin B.
The green leaves are a good source of vitamin C.
Folkloric
- Root decoction taken for asthma and as general stimulant.
- Leaves used for hemorrhoids.
- In Costa Rica, decoction of leaves used as remedy for diseases of the kidney and bladder.
- In El Salvador, seeds used as a remedy for colds.
- In Yucatan, decoction of leaves used for cleansing wounds.
- Root, boiled with sour milk and grain porridge used to treat syphilis.
- Juice of fruit with pounded leaves and roots used for a variety of skin diseases.
- Roots, dried stalk, and leaves used in decoction for washing sores.
- Astringent for bladder hemorrhage.
- Decoction or infusion of leaves used for stomach problems.
- Burnt fruit used for liver problems.
- Fruit is cooling, and when bruised with vinegar, is used as a poultice for abscesses and cracked nipples.
- Fruit used for phthisis, cough and loss of appetite.
- The peduncle (stalk of flower or fruit) when burned is used for piles, toothache and intestinal hemorrhages.
- Seeds are used as stimulant but may cause dyspepsia and constipation.
- In Belize, leaf juices rubbed to afflicted areas with athlete's foot.
- In Bolivia, fruit used for scabies.

Others
- Decorative: Fruit collected ripe with the branches used for interior decoration.
- Repellant / Insecticide: Kofan people of Columbia and Ecudaor use the plant as insect repellant especially against cockroaches. (7)
- Poison concerns: Parts of the plant are toxic. Species used as poison against cockroaches, rats, and insects. (Hanelt et al, 2001) ( 11) In Columbia, identified as poisonous to cattle, causing prostration. (13)
- Rituals: Fruits and foliage use as floral arrangements for religious festivals. Fruits use during Chinese Lunar New Year celebrations with the fruit color symboizing wealth. (Lim, 2013) (11)(12)

Studies
Antiproliferative / Indioside D: Study isolated indioside D, a furostanol glycoside from Solanum mammosum and was found to possess antiproliferative activity toward a panel of human cancer cell lines. Results showed indioside D induced apoptosis in HeLa cells via both intrinsic and extrinsic cell death pathways. (1)
Anticancer / Saponins / Solamargine: Of saponins isolated from the fruit, solamargine showed highest toxicity towards HeLa cell line followed by inidioside D, protodioscin, solasonine and pseudoprotodioscin. (7)
Antimalarial: In a study of 46 different species screened for antimalarial activity, Solanum mammosum fruit extract was one of those found moderately active. (2)
Antioxidant Activity: Study by Weitwitayaklung and Phaechamud (2011) reported low antioxidant activity of S. mammosum fruit, with a total phenolic content of 3.08 g/100 g crude extract gallic acid. (7)
Molluscicidal: Steroidal glycoalkaloid mixed from fruits, solasonine and solamargine and the stereoisomeric glycosidic alkaloid tomatine were toxic to Lymnaea cubensis and Biomphalaria glabratus.
(7)
• Solasodine in Steroid Production:Solasodine, present in Solanum mammosum, can be a potential alternative for the high-revenue synthesis of steroid hormones. Study reports on the use of added methyl jasmonate, cholesterol, and L-arginine into the modified liquid full-strength MS medium could influence the solasodine production in the hairy roots of S. mammosum. The amount of solasodine was five times higher than those without both elicit or and precursor treatment. The improved solasodine production with high biomass growth can reduce the production cost of steroid synthesis in the long run. (8)
• Microbicidal Synergism Against Potomac Catalina: The species Solarium mammosum, S. saponaria and Jatropha curcas have shown molluscicidal properties against Pomacea canaliculata. Study evaluated a mixture of aqueous extracts of the three plants for synergistic effect between them. All were diluted to 500 ppm. Mixes with best results on mortality were choses to determine the LD50. The formulations of S. saponaria (100%) and S. mammosum and S. saponaria (50%-50%) showed best results with LD 50 of 24.04 ppm and 17.78 ppm, respectively, with no significant statistical differences between each other to a confidence of 95%. While no synergistic effect was found between mixture of aqueous extracts of the three species, the mixing of Sapindus saponria and Solanum mammosum can be useful in areas where the effectiveness of S. saponaria is restricted by environmental conditions, such as low availability of oxygen in the water. (9)
• Microbicidal Steroid Alkaloids: Steroidal alkaloids mixture from fruits (solasonine 1 and solamargine 2) and the stereoisomeric glycosidic alkaloid tomatine 3 are toxic at 10 and 25 ppm to Lymnaea cubensis and Biomphalaria glabratus, respectively Their aglycones solasodine 4 and tomatidine 5 obtained by hydrolysis of glycosides showed no toxicity to either mollusk. (14)

Toxicity
- Despite known toxicity some reports list the fruits and leaves as palatable. (Lim, 2013) (12) (11)

Availability
- Wild-crafted.
- Seeds in the cybermarket.
