An annual erect or procumbent herb. Leaves sessile, 1.25-3.7 cm, long, opposite, rarely wlorled, ovate, acute, gland-dotted. Flowers, axillary, solitary, blue. Sepals almost equaling the corolla, narrow, lanceolate, acuminate. Corolla 8-12 mm diam., segments often ciliate. Capsule size of a small pea.

Plant extract possesses antifungal properties. EtOH(50%) extract of the plant is a potent uterine stimulant on isolated guinea-pig uterus. MeOH extract of aerial parts is estrogenic in mice (Asolkar et al., 1992).

Chemcial Constituents:

Aerial parts contain alkaloids, bitter cucurbitacin glycosides, arvenin, I and II and cucurnitacin, B, D and E, sterols, ß-amyrin, rutin, n-hexacosane, lacceric acid, triterpenes anagalligenone, anagalligenin, carbohydrates and enzymes. Aerial parts also contain ß-sitosterol and stigmasterol. A new triterpene metabolite with an olanane skeleton, the sterols, a-spinasterol, ?7-avenasterol, dihydrospinasterol, ß-sitosterol and stigmasterol, fatty acids such as palpitic, stearic, oleic and linoleic acids and the triterpene saponins, anagallosides A, B, C and deglucoanagallosides A and B have been isolated from leaves. Flowers contain sterols, stigmasteriol, ß-sitosterol, a-spinasterol glucoside, kaempferol, quercetin and rutin. Roots contain saponins of triterpenoid series. Roots also contain cucurbitacin glycosides, which on keeping yields cyclamin. Unsaponifiable matter of seed oil contains higher alkanols, stigmasterol and sitosterol (Ghani, 2003; Asolkar, et al., 1992).
