Abstract
Medicinal plants have rich source of secondary metabolites, which can be screened either qualitatively or quantitatively. It is an important procedure for qualifying the plant drug and their potentialities. The active phytomoleucles present in a plant reflect the therapeutic values of medicinal species. In order to discover a new bioactive compounds from plant resources which could become new leads or new drugs, plant extracts should be simultaneously evaluated by appropriate screening methods by either biological or pharmacological targets. For the extraction procedures, solvent extraction is commonly employed for extraction of most active principles from the plants. Entada sp. showed more than 27 different components of phytochemicals with a rich source of polysaccharides whereas polysaccharides only have major drug potential which was carried out by GC-MS analysis. In the recent studies, the bioactive components of seed of Entada pursaetha using GC-MS were investigated using Perkin-Elmer Gas Chromatography-Mass Spectrometry, while the Mass spectra of the compounds found in the extract was matched with previous literature.
Highlights
Medicinal plants are being the main resource of secondary metabolites which can be used as potent drugs
Interpretation on mass -spectrum Gas Chromatography-Mass Spectrometry (GC-mass spectrometry (MS)) was conducted using the database of National Institute Standard and Technology (NIST) having more than 62,000 patterns
A portion of dried aerial parts (100 g) of Entada pursaetha DC was placed in a soxhlet apparatus
Summary
Medicinal plants are being the main resource of secondary metabolites which can be used as potent drugs. They have been an important source of medicine for curing innumerable ailments since thousands of years. Kalimuthu and Prabakaran (2013) reported that the medicinal plants are increasingly valuable importance for extracting principal resources of nutraceuticals, traditional medicines and food supplements. The official values of medicinal plants are depending on their bioactive phytoconstituents. These phytoconstituents are being identified in medicinal plants can be used to cure many diseases and disorders and can be studied for their definite physiological activity in the human body. The isolation, identification and screening of chemical constituents present in herbal medicines have been of great interest to the scientists for discovering novel therapeutic drugs, and the effective in remedy for several diseases (Sylvestrea et al, 2006)
