All findings suggest that the antifertility activity of extract could possibly be through the changes in the implantation site, altered hormonal levels, prolonged estrous cycle and anti-estrogenic activity. Hence, the extract possesses reversible antifertility activity without adverse toxicity in female rats.
Amaranthus spinosus Linn. (Amaranthaceae) is found throughout India. This tree species has been of interest to researchers because it is a medicinal plant employed in the Indian traditional system of medicine. Pharmacognostic standardization; physico-and phytochemical evaluation of the roots of Amaranthus spinosus was carried out, to determine its macro-and microscopical characters, and also some of its quantitative standards. Microscopical studies were done by using the trinocular microscope. Total ash, water-soluble ash, acid-insoluble ash, sulfated ash values, and alcohol-and water-soluble extractive values were determined for physico-chemical evaluations. A preliminary phytochemical screening was also done to detect different phytoconstituents. Microscopically, the root showed cork, cortex, stellar region, and calcium oxalate crystals. Powder microscopy showed anamalous secondary growth in between the xylem vessels and Calcium Oxalate crystals in the cortex region. Total ash was approximately three times more than acid insoluble and water soluble ash. The ethanol soluble extractive was approximately the same as the water soluble extractive. Thin Layer Chromatography (TLC) of the Petroleum-ether extract using Benzene : Ethyl acetate (6 : 1), showed six spots. In the chloroform extract, using Benzene : Ethyl acetate (4 : 1) nine spots were seen, and in the ethanol extract, using Chloroform: Methanol (93 : 7), only four spots were observed, using Iodine vapor as a viewing medium. Phytochemically, the root exhibited terpenes, alkaloids, glycosides, and sugars. These findings might be useful to supplement information with regard to its identification parameters, which are assumed significant in the way of acceptability of herbal drugs, in the present scenario, which lacks regulatory laws to control the quality of herbal drugs.
Piper betle (Petiole) is used of herbal methods for fertility regulation is widely accepted alternative for the synthetic drugs containing chemical having side effects. Piper betle (Petiole) is the plant having several medical properties but no reports were available on the antifertility activity. The aim of this study was to investigate the antifertility activity of extracts of Piper betle (Petiole) on female wistar rats at the doses 500 mg/kg b.wt./day for 30 days. Different parameters were studied in female wistar rats including effect of Reproductive outcome, Anti-implantation, Abortifacient and Estrogenic & Anti-estrogenic activity, were observed. Piper betle shown positive test for Alkaloids, Steroid, Flavonoids, Terpene, Carbohydrates and Tannin. The extract has anti-fertility effect the control rats showed good number of litters and treatment of animal with different extracts resulted a significant (P < 0.05, P < 0.01). Antifertility activity 51% and 37.2% was exhibited by Alcoholic extracts of Piper betle (Petiole) APB and Aqueous extracts of Piper betle (Petiole) WPB respectively. After 21 days of the extracts free period, the antifertility effect of the extracts was reversed. The extract treatment with APB, an increase in the percentage of resorption index indicates the failure in development of embryo. The mean percentage of anti-implantation and abortifacient were found to be highest for APB-38.45%, WPB 13.62, and APB-28.96%, WPB-12.75% respectively. The decrement in implantation caused by the extracts may be due to estrogenic or anti-estrogenic activity. However, along with standard APB exhibiting more potent estrogenic and less potent anti-estrogenic when compared with standard. Female antifertility agents should include acceptability, safety and efficacy during and after the treatment. The above results revealed the potential, reversible female antifertility effect of alcoholic extract Piper betle (Petiole).
Acacia leucophloea (Mimosoideae) is native to Southeastern Asia. This tree species has been of interest to researchers because it is a medicinal plant employed in the Indian indigenous system of medicine. Pharmacognostic standardization, physico-chemical evaluation of the roots of Acacia leucophloea was carried out to determine its macro-and micro-scopical characters and also some of its quantitative standards. Microscopical studies were done by using trinocular microscope. Total ash, water-soluble ash, acidinsoluble ash and sulphated ash values, alcohol-and water-soluble extractive values were determined for phytochemical evaluations. Preliminary phytochemical screening was also done to detect different phytoconstituents. Microscopically, root showed cork, cortex, stellar region and calcium oxalate crystals. Powder microscopy showed crystal fibres, xylem fibres in bundle, phloem fibres, medullary ray, and cork cells, parenchyma cells with red cell content, tissues with abundant xylem vessels with pitted thickenings, parenchyma, and Stone cells. Total ash was approximately two times and four times more than acid insoluble and water soluble ash, respectively. Ethanol soluble extractive was approximately two times higher than water soluble extractive. TLC of petroleum ether and chloroform extract showed nine spots using benzene:methanol (19:1) and chloroform:methanol (19:1) respectively while ethanol extract showed four spots using ethyl acetate. Phytochemically, root exhibited alkaloids, terpenes, flavanoids and tannins.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
