medicinal plants

This work is devoted to phytochemical study of tannic extracts from the leaves of Combretum paniculatum (CP), Mallotus oppositifolius (MO) and Ximenia americana (XA), three medicinal plants of Ivorian flora, used in traditional medicine against certain types of cancer. Qualitative analysis by phytochemical screening of these extracts, performed by means of TLC, revealed in addition to hydrolysable and condensed tannins, the presence of phenolic acids and flavonoids. Total tannin contents determined by permanganometry and spectrophotometry are respectively 41.03 ± 0.77% and 12.3648 ± 0.0004% for MO; 20.03 ± 0.44% and 11.7974 ± 0.0001% for XA; 18.76 ± 0.89% and 11.6026 ± 0.0008% for CP. Condensed tannin content in XA leaves (234.135 ± 0.003 µg ECT/mg) is considerably higher than in CP (37.731 ± 0.001 µg ECT/mg) and MO (19.082 ± 0.001 µg ECT/mg). All XA extracts (aqueous and ethyl acetate) have shown good antioxidant activity with CR50s which are lower than that of vitamin C (reference antioxidant). A correlative relationship was found between tannin content and antioxidant activity.

In order to gather all the information concerning the nature and the therapeutic uses of the medicinal plants, an ethnobotanical study of the medicinal plants was realized Oran city’s circle, between December 2017 and April 2018. This research was conducted in collaboration with different plant users such as ordinary users (500 people) who were randomly selected (340 women, 160 men). The survey targeted 500 people from the local population, including 423 people preferring medicinal plants with a rate of 84% and 77 people who received treatment in modern medicine with a rate of 16%. The results obtained from the population made it possible to identify 58 medicinal plants which are divided into 34 families, of which three are the most dominant, in particular Lamiaceae (29.55%), Apiaceae (17.96%) and Verbenaceae (14.65%). all listed plants with properties against allergy. the leaves are the most used organs (34%) and the majority of the remedies is prepared as an infusion (58%), the respiratory diseases occupy the first place with a rate of 42%. The results obtained constitute a very valuable source of information for the region studied and for the national medicinal flora. They could be a database for further research in the fields of photochemistry and pharmacology and for the purpose of searching for new natural substances.

One of the most critical problems of throughout the world especially in developing and underdeveloped countries is the increase in human population. Fertility control is an issue of global and national public health concern. Sexual and reproductive health is a prerequisite of all goals because it has a direct link to social, economic and human development. Family planning has been prompted through several methods of contraception, but due to adverse effects produced by synthetic steroidal contraceptives attention has now been focused in indigenous plants for possible contraceptive effect. Contraceptive ability of plants has been reported in several animal models. The reversibility of the anti-fertility effects of plants and its active compounds are of potential clinical relevance in the development of contraceptive. This review attempts to focus on the potential of medicinal plants as the source of new contraceptive principles.

The present study revealed that, acetone among pure forms of experimental solvents and Ethyl acetate + Methanol + Water among the mixture forms could extract significantly higher (p
