Most drugs based on herbal plants for manufacturing of chemicals; hence herbal plants are major importance in biotechnology research. Many herbal constituents used as flavors, fragrances, pharmaceutical chemicals and food colors in India. The most of the herbal product were prepared from plant extracts, which contain different phytochemical constituents (plant secondary metabolite). The amount and identity of produced compound was correlated with therapeutic effect. The GC-MS used to analyze the extracted extract, that is useful for the determining the quantity of active principles in herbal plants used in cosmetics, medicines, food industries and pharmaceutical. The purpose of this study was to use gas chromatography and mass spectroscopy to identify the bioactive compound from entire plants. The GC-MS analyze the presence of various alkaloid, terpenoid, flavonoidal and glycoside phytoconstituents in herbal plants.
