“…However the vast majority of saponins have been tested for their effects on fresh water mollusks which are vectors of some epidemic disease such as malaria and Schistosomiasis (Diab et al, 2012;Winder et al, 1995;Akinpelu et al, 2012;Aladesanmi et al, 2007;Abdel-Gawad et al, 1999). Gonzalez-Cruz and San Martin (2013) investigated the molluscicidal effects of saponin-rich plant extracts via forced oral injection on the grey field slug.…”

Styrax officinalis is a deciduous large shrub that grows in many Mediterranean countries. Active ingredients are localized in the fruit pericarp. Primary phytochemical analysis showed the presence of saponins, tannins and triterpenes and absence of alkaloids and flavonoids. No antimicrobial, but strong ichthyotoxic and molluscicidal effects were observed in the saponin-rich extract .Toxicity tests with the snail Cornu aspersum proved to be a potent contact molluscicide. Allowing the snail to creep on leaves and surfaces sprayed with a 1% (w/v) of pericarp extract resulted in severe dehydration and foaming through their membranes, which resulted in their death after 30 min. When the snails were fed lettuce leaves treated with the same extract solution, it did not cause any observable effect. These findings show that S. officinalis is a promising natural source of a potent contact molluscicide with no visible effect on the snail upon ingestion.

“…Saponins also act as anticancerous, and antiangiogenic agents and have been reported to inhibit the progression of the cell cycle and induce apoptosis [65]. The other activities attributed to saponins include antioxidant, anticarcinogenic, immunostimulatory, antibacterial, antifungal, antiviral, antiprotozoal, hypoglycemic, hemolytic, immune adjuvant and membrane permeabilizing [62,63,64]. The saponins were present in all the extracts of O. indicum, and M. pachycarpa, except the chloroform extract of the former.…”

“…The presence of cardiac glycosides reaffirms their use a traditional medicine.Saponins are produced by plants to protect them against pathogens and herbivory. They have been found to kill fungus, insects and molluscs that attack plants and also act as allelopathic [62][63][64]. Saponins also act as anticancerous, and antiangiogenic agents and have been reported to inhibit the progression of the cell cycle and induce apoptosis [65].…”

The humans have used medicinal plants for healthcare since the time immemorial. The systematic phytochemical analysis of traditionally used medicinal plants is needed to establish their use as medicine. Oroxylum indicum and Milletia pachycarpa have been used in India and China to treat various health related disorders. Therefore it was decided to undertake phytochemical and Thin Layer Chromatography (TLC) profiling of different extracts of Oroxylum indicum and Milletia pachycarpa using standard procedures. The dried powder of stem bark of Oroxylum indicum and root bark of Milletia pachycarpa was sequentially extracted in chloroform, ethanol and water. The dried extract of each plant was phytochemically analyzed for the presence of alkaloids, flavonoids, cardiac glycosides, phytosterols, saponins, tannins steroids and phlobatannins. Each extract from both plants was processed for TLC profiling on silica gel using various solvent combinations as mobile phase. The phytochemical analysis showed the presence of alkaloids in chloroform and ethanol extracts, whereas alkaloids were absent in aqueous extract of both Oroxylum indicum and Milletia pachycarpa. The flavonoids were observed in all extracts of both plants. However, cardiac glycosides were absent in the aqueous extract of Milletia pachycarpa. The saponins were detected in all the extracts of both plants except the chloroform extract of Oroxylum indicum. The tannins could not be detected in the aqueous extract of M. pachycarpa. The phlobatannins were absent in all extracts of both plants. Steroids exhibiting a wide variety of biological activity [8]. Almost every part of this tree possesses medicinal properties and has been used in several traditional Ayurvedic and folk medicines [18]. O. Indicum has been reported to possess several medicinal properties including analgesic, antibacterial, anti-inflammatory, anticancer, antioxidant [19][20][21][22][23]. Therefore, an attempt has been made to study the phytochemical constituents of Milletia pachycarpa and Oroxylum indicum. Materials and Methods Preparation of the extractThe non-infected stem bark of O. indicum was collected from Champhai whereas root bark of Milletia pachycarpa was collected from Kolasib district of Mizoram, India during the dry season in the month of January. The identification of plant was done by the Department of Horticulture and Aromatic and Medicinal Plants, Mizoram University, Aizawl, India. The barks of both plants was washed thoroughly with clean water and allowed to shade dry at room temperature in the dark in clean and hygienic conditions. The dried barks of both plants were separately powdered using an electrical grinder at room temperature. The powdered bark of O. indicum stem or root bark of M. pachycarpa was sequentially extracted with petroleum ether, chloroform, ethanol and distilled water according to increase in polarity using a Soxhlet apparatus until the solvents became colourless [24]. The liquid extracts were concentrated by evaporating their liquid contents using ...

“…It is one of molluscicidal medicinal plants from Nigeria. All isolated compounds from the fruits or other parts were found to exhibit strong molluscicidal properties against the snail B. glabrata (Aladesanmi, 2006). Alcoholic extracts of six medicinal plants of Brazilian cerrado were assessed for their molluscicidal activity on B. glabrata.…”

Schistosomiasis is a neglected disease that affects approximately 200 million people worldwide. In order to reduce the parasite prevalence, further researches aiming new treatment methods is necessary. Once infected by Shistossoma mansoni, one can have no symptoms in the acute phase, however, chronic phase is characterized by marked egg-induced hepatic granulomatous inflammation. To prevent the disease, the main prophylactic method is environmental sanitation which decreases the entrance of eggs into water bodies. In addition to fighting the snail, treatment of population is important. Currently, for treatment of schistosomisasis, the most used drugs are Praziquantel (PZQ) and Oxamniquine, whereas PZQ is the drug of choice. Each drug has a specific mechanism of action aimed at the elimination of the parasite. However, any parasite treatment based on the use of a single drug poses serious concerns regarding the onset of resistance. The search for new therapeutic agents derived from medicinal plants for schistosomiasis has progressed significantly in the last decade. The aim of this paper is to provide an updated survey on medicinal plants that have significant therapeutic effects in animal models of schistosomiasis. A considerable number of herbal constituents with schistosomicidal effect have been well characterized and may be good candidates for prospective studies and investigations that may result in clinical usage.
