Vitex negundo Linn. (Verbenaceae) is a hardy plant, which has enormous traditional uses against various diseases, flourishing mainly in the Indian subcontinent and is commonly used herb in Ayurvedic medicine. The present review aims to compile information on its, medicinal values phytochemical and pharmacological activities, traditional uses and scientific approach generated through the research activity using modern scientific approaches and innovative scientific tools.The plant extracts have been widely used for the treatment of a large number of human ailments. The chemical entities of this plant have been used as an antidiabetic, antibacterial, anti-inflammatory, antifungal, anti-nociceptive, anti androgenic, anticonvulsant, antioxidant, and anti-tumor agents. Scientifically proved activities are related with traditional concept....
As a consequence of normal metabolic processes, the body produces reactive oxygen species (ROS) capable of oxidizing biomolecules that can damage DNA as well as contribute to chronic diseases. This procedure can be inhibited by consumption of herbal plants which have ability to scavenge ROS, RNS and other radicals. The present study was aimed to evaluate the free radical scavenging potential of leaves and seeds (OC) extract of Ocimum canum to exhibit their reducing ability. The maximum scavenging was seen in alcoholic extract of leaves of OC with IC50 value 51.38 �µg/ml for iron chelation assay. The data obtained in present study suggests that the leaves of OC have potent antioxidant activity against free radicals and also exhibited an immense reducing ability...
Pakistan is land of cultural and geographic diversity; same is the case with the natural flora of this land. The flora is rich in the medicinal plants, majority of the plants are utilized by the local people without scientific evidence. Need is to identify such plants, screen out the active constituents and search out the biological secret embedded in them. Such investigations can lead to the safe and effective molecules which could establish as major remedies. Euphorbia prostrata is one of the examples of such plants. It belongs to family Euphorbiaceae also called spurge family. This plant contains anthraquinone glycosides, flavanoids, phenols, phlobotannins, polysaccharides, saponins, tannins and terpenoids. This plant is used as antidote for sting poisoning and to avoid painful menstruation also to avoid the miscarriage. This herb is useful remedy for number of problems. In view of the importance of this plant is reviewed and is being presented in this article....
Phytoconstituents have proved to possess the potential to calm, smoothen, heal, rejuvenate and protect the skin. This has led to their increased use in cosmetics. Phytoconstituents are being extracted by microwave assisted techniques tremendously since last few years due to the advantages which they offer over conventional extraction techniques. Microwave assisted extraction (MAE) is a separation technique that combines the uses of energy of microwave radiation and traditional solvent extraction. It is not only time and solvent saving but also a boon to thermo labile constituents in plant material. Also, the dangers of hazardous organic solvents to nature, environment and operator are minimized due to lower amount of solvent required. MAE has shown to provide higher quality, purity and yield of phytoconstituents when compared to the conventional extraction techniques like Ultrasonic Assisted Extraction and Soxhlet extraction. It can be applied to solid, semi-solid and liquid matrices and the ability to alter and adjust solvent polarities renders it widely applicable. The phytoconstituents used in herbal cosmetics that have been reported to be extracted by MAE include lipids (fatty acids and oils), terpenes (essential oils, sterols, and carotenoids), polyphenols (flavonoids) etc. The aim of the study is to throw light on the potential and advantages of MAE and hence suggest its increased utilisation in the herbal cosmetics industry. A brief theory of microwave heating and the basic principles of using microwave energy for extraction have also been presented in this article....
Objective of present work is to study detailed Pharmacognosy of the leaves of Nyctanthes arbortristis Linn (Oleaceae), an important plant in Indian system of medicine. Macroscopy, microscopy, physicochemical analysis, preliminary phytochemical testing of powder of the plant leaf and other WHO recommended methods for the standardization was done. Results showed that leaf is dorsiventral type as palisade cells are present towards one side of the lamina. Xylem and phloem are observed in the TS of midrib surrounded by sclerenchyma cells. Discontinuous strips of sclerenchyma cells are present surrounding to the phloem tissue is observed in the TS of the midrib. The stomata observed are actinocytic. Surface view showed branched vein terminations that are ââ?¬Ë?dendroidââ?¬â?¢ in outline. Preliminary phytochemical screening ascertains presence of steroids and triterpenes in petroleum ether and chloroform extract, alkaloid and flavonoids in ethyl acetate and ethanol extract and alkaloid, tannins, glycosides, carbohydrates and flavonoids in aqueous extract of the plant bark. It can be concluded that the pharmacognostic profile of N. arbortristis leaves is helpful in developing standards for quality, purity and sample identification....
