Introduction
Plants considered being very rich sources of secondary metabolites which are having therapeutic importance. Majority of world’s population in developing countries still relies on herbal medicines to meet its health needs. In recent times, focus on herbal research has increased globally and evidence collected from different research survey shows the immense potential of medicinal plants used in Indian system of traditional medicines.1
The important advantages of medicinal plants in various treatments are due to their fewer side effects, less expensive, more efficacy and availability throughout the world.2 The World Health Organization has estimated more than 80 % of the world’s population in developing countries depends primarily on herbal medicines for their basic healthcare needs. 3 The practitioners of traditional system of medicine treat about 80% of patients in India, 85% in Burma and 90% in Bangladesh. 4, 5 Medicinal plants are the richest bio resource of drugs for traditional systems of medicine, modern medicines, Nutraceuticals, food supplements, folk medicines, pharmaceutical intermediates and chemical entities for synthetic drugs. Medicinal plant plays a main role in the growth of new herbal drugs. The majority of the medicinal plants are collected from the wild and recently some medicinal plants are cultivated by farmers. 1, 6

Saboo et al. 27, 28 reported the chloroform extract of Trichosanthes tricuspidata root shows a significant antibacterial activity. The different extracts (n-butanol, acetone, methanol and aqueous extracts) of Trichosanthes tricuspidata fruits were shows antibacterial activity against Streptococcus pyogenes, compare to all extracts methanolic extract shows more active. 14
Trichosanthes tricuspidata leaves petroleum ether, chloroform, ethanol, methanol and acetone extract was tested against Gram positive and Gram negative pathogens. 29 Ethanol extract showed greater inhibitions against Bacillus cereus Klebsiella pneumonia, Klebsiellaoxytoca and Brevebacterium paucivorans. Ethanol extract shows a significant antibacterial activity when compare the other extracts.
Anthelmintic Activities
Ethano- botanically this plant was used by tribals to treat an intestinal worm infection which shows significant anthelmintic activity reported in experimental laboratory model. Anthelmintic activity of Trichosanthes tricuspidata was carried out by Dubey. 30 In this investigated the aerial parts of Trichosanthes tricuspidata extracted with ethanol and water. Both extracts showed a more active when compared with standard drug albendazole. Anthelmintic activity of both extracts was dose-dependent manner. Ethanolic extract of Trichosanthes tricuspidata showed more active then aqueous extract.
Antioxidant Activity
Antioxidant activity of different plant parts (leaf and fruit) of Trichosanthes tricuspidata were reported by Rodge et al. 31 In this study fruit part of the Trichosanthes tricuspidata was showed more antioxidant activity compared to leaf was reported in the chloroform extract of Trichosanthes tricuspidata. 28 root showed more antioxidant activity compared to standard. It was reported the methanolic extract of Trichosanthes tricuspidata leaves exhibited good antioxidant activity. 32
Antifungal Activity
Anti-Fungal Activity of Trichosanthes tricuspidata roots was carried out in chloroform extract of Trichosanthes tricuspidata roots showed a significant antifungal activity screened by agar- well diffusion method. 28
Larvicidal activity
Trichosanthes tricuspidata used as natural mosquito repellent, it may be helpful in the house to kill the mosquitoes, mice, etc. Sonwalkar et al., 33 was reported the Trichosanthes tricuspidata fruit used as larvicidal activity. In this investigated two different extracts (methanol and petroleum ether) showed significantly high active mortality comparing with control. Methanolic fruit extract of Trichosanthes tricuspidata showed more larvicidal active then petroleum ether fruit extract.
Anti-hyperglycaemic activity
Trichosanthes tricuspidata root extract was reported to cure the antidiabetic and hypollipidamic activity, 34 studied carried out the ethanolic extract of Trichosanthes tricuspidata root was used to estimate the anti-diabetic activity of alloxan induced diabetic rats and biochemical parameters like cholesterol, triglyceride, serum protein, SGPT, SGOT, and ALP. Alloxan treated rats contain high blood glucose level when compared with normal control. Oral administration of ethanolic extract of Trichosanthes tricuspidata root was showed significantly decreased blood glucose level.
Gastro protective activity
Kannan et al reported the different extracts (Hexane, Chloroform, Ethanol and Water) of Trichosanthes tricuspidata leaves were compared with standard Ranitidine drug 35. The Hexane extract showed significant high gastro protective activity when compared with all other extract.
The anti-haemolytic activity
Anti-haemolytic activity of methanolic extract of Trichosanthes tricuspidata leaves was reported by36 anti-haemolytic activity screened by haemolysis of cow erythrocyte the plant extract was compared with the standard butylated hydroxy toluene (BHT).The methanolic extract of Trichosanthes tricuspidata showed 26.7% inhibition at 500 μg/ml concentration whereas standard BHT shows 89.63% at 500μg/ml.
Anti-pyretic activity
Kannan et al 37 reported the different extract (ethanol and aqueous extract) of Trichosanthes tricuspidata Linn. Leaves contain anti-pyretic activity. Experimental analysis of the extracts was significantly reducing the body temperature of rats when compared to the standard paracetamol drug. Trichosanthes tricuspidata ethanol extract showed more antipyretic activity when compare to the aqueous extract.
Anti-inflammatory activity
The Trichosanthes tricuspidata ethanol extract showed the anti-inflammatory activity in lipopolysaccharide (LPS-) stimulated macrophages and mouse models of acute inflammatory disease. 38
Anticonvulsant activity
The Epilepsy prevails to be a neurological disorder in anticipation of safer drugs with enhanced anticonvulsant efficacy as presently available drugs fails to offer adequate control of epileptic seizures in about one-third of patients. 32 Evaluate the effect of Trichosanthes tricuspidata ethanolic extract (TTME) against epilepsy mediated oxidative stress in pilocarpine induced mice. The seizure was accompanied by significant increase in lipid peroxidation and the hippocampal nitrite content in pilocarpine group when compared with control. Moreover, the antioxidant enzymes superoxide dismutase, catalase and glutathione levels were decreased in pilocarpine administered groups. Methanolic extract administration attenuated oxidative damage as evident by decreased lipid oxidative damage and nitrite– nitrate content and restored the level of enzymatic antioxidant defences in hippocampus. Involvement of free radicals during epilepsy is further confirmed by histopathological analysis which showed the loss of neuronal cells in hippocampus CA1 and CA3 pyramidal region. The findings strongly support the hypothesis that TTME has anticonvulsant activity accompanied with the strong antioxidant potential plays a crucial role in reducing the oxidative stress produced by seizure. 32
Anticancer activity
Chloroform extract of Trichosanthes tricuspidata root was showed most promising anticancer activity. 28 They investigated the chloroform extract of roots contain 32 mg/gm of gallic acid and 28.5mg/gm of tannic acid. The chloroform extract exhibited potent cytotoxicity with an IC50 of 42.88, from the data obtained, it was observed that chloroform extract effective against L1210 and MCF-7 whereas extract have moderate effect on PC3 comparable to the standards Adriamycin.
