ANTIMYCOTIC ACTIVITY IN AQUEOUS EXTRACTS OF PLANTS
ANTIMYCOTIC ACTIVITY IN AQUEOUS EXTRACTS OF PLANTSWater extracts from plant and plant products provide a mixture of water soluble components in their natural forms. Whether, plant components in their natural form can be used against fungal infections become a matter of enquiry amongst the scientists who believed that natural products can prove a better therapeutants than antibiotics for the treatment of fungal infections. Water extracts from fresh leaves of some medicinal plants i.e., Nerium indicum Mill, and Eucalyptus globulus have been found highly toxic for the growth of Nannizzia gypsea strain + (IMI 86524), N. gypsea strain – (IMI 86176), N. fulva strain + (IMI 160138), N. fulva strain – (IMI 160139), N. incurvata strain + (IMI 86523), N. incurvata strain – (IMI 86519) causing cent per cent growth inhibition in all the test fungi when tested by poisoned food technique. Similar report on the antimycotic properties of aqueous extracts from leaves of marrygold, and sukhadarshan, bulb of onion and garlic and rhizome of ginger has also been made by Rathore against some soil inhabiting keratinophilic fungi. Aqueous extracts from above plants have also showed strong sporostatic activity against Aspergillus niger, A. flavus, Absidia corymbifera, Penicillium nigricans and Candida albicans, the isolates of human ear. Beside these, there are some early reports on the antimycotic properties of some plant extracts. Above workers have indicated strong mycotoxicity in some of their test plants. Antimicrobial property has also been reported in some organic solvent extractives of Dillenia indica Linn.Black pepper and cardamom have also been reported to possess antimicrobial property and thus these are in frequent use in the treatment of various diseases. Several other plant products which are used as spices are also well known for antibacterial and antifungal properties and are used for beauty and body care.*6\218\2*
