Aim of this study was to determine the presence of phytochemical components in Saussurea obvallata and Pittosporum eriocarpum, two endangered medicinal plant species of Uttarakhand. Phytochemicals are non-nutritive plant chemicals that have protective or disease preventive properties. These components are produced by plants to protect themselves, but recent researches demonstrate that they can also protect humans against diseases. Our research shows the presence of active components in Brahma kamal and Agni extract with different solvents like methanol, ethanol, chloroform, and distilled water. Traditionally these herbs had been used for the treatment of various disorders like paralysis of limbs, cerebral ischemia, narcotic, expectorant, bronchitis, urinary tract problems, cough, etc. Our results indicated the presence of active components like alkaloids, flavonoids, terpenoids, etc. These components are responsible for the modulation in different disorders like Alzheimer, stroke, and epilepsy, etc. Our research team is carrying out a detailed investigation of components and its role in different...

The spermicidal activity of Elettaria cardamomum and Cuminum cyminum seed extracts have been studied to evaluate the effective concentration to immobilize and kill 100% of sperm within 20 s, and the sperm function of rat is studied to find the effect on sperm membrane integrity. Sander and Cramer’s test was used to study the spermicidal activity of Elettaria cardamomum and Cuminum cyminum. Sperm viability and sperm morphology were studied using Eosin-Nigrosin staining technique. Stability of the extracts was studied by storage of extracts at –20 °C. Under the test conditions, minimum effective spermicidal concentrations for Elettaria cardamomum and Cuminum cyminum seeds extract are 1 mg/million sperm and 5 mg/million sperm respectively. The effect of the extract on morphology and viability of sperm was also studied, and no change was observed in the morphology of head, midpiece, and tail and no viable sperm seen. The effect of different concentrations of extracts of Elettaria cardamomum and Cuminum cyminum on percentage motility of the sperm was also studied. With an increase in...

In continuation of our study we have screened out the root, leaf, and stem of C. viscosum against rice weevil, S. oryzae extracted into ethanol, ethyl acetate, and chloroform. A correlation was found between the insecticidal and repellent activity observed by residual film assay technique and repellency test. It is interesting to note that these plant extracts showed higher to less mortality activity by using 3.93, 1.97, 0.98, 0.49 and 0.25 mg-cm-2 doses. From the overall assessment suggested that the root extracts showed most potency. Ethanol fraction of root extract exposed 44-84% mortality with 0.39 mg/ml of LC50 value at 72 h of exposure and 95% confidence limit was 0.19 – 0.80. Repellency test carried out ethanol fraction. All the extracts showed 100% repellency (Class V category repellency) in dose no 1 to a dose no 5. The degree of repellency response among the three parts of the test insect was significantly different (P<0.05). Class V category repellency was observed for root and leaf up to dose 0.06 mg-cm-2...

Both physicians and dermatology patients are searching for long term skin care solutions to address problems presented by skin hyperpigmentation. Traditional depigmenting agents such as hydroquinone, corticosteroids, kojic acid, although highly effective, can raise several safety concerns (for example, ochronosis, atrophy, carcinogenesis, and other local and systemic side effects) with long term exposure. An understanding of the benefits of natural and botanical extracts provides opportunities to develop new products to address pigmentation problems. This study presents an overview of trends in the application of plant extracts for the treatments of hyperpigmentation disorders. It highlights some of the potent natural products, their specific components, mode of action and optimum...

The Siddha System of Medicine (Traditional Tamil System of medicine), which has been most prevalent in the ancient Tamil land, is the foremost of all other medical systems in the world. Since, ancient times, several diseases have been treated by administration of plant extracts based on traditional medicine. Plants are the only economic source of some well established and important drugs. Indian Materia Medica includes about 2000 drugs of natural origin. The National Siddha Formulary of India lists more than 10000 well practiced Siddha formulations described in Gunavagadam (Siddha pharmacology). Cyperus rotundus Linn. belongs to the family Cyperaceae. It is the world worst weed native to India. It has a wide range of medicinal and pharmacological applications. According to the Siddha, C. rotundus rhizomes are considered astringent, diaphoretic, diuretic, analgesic, antispasmodic, aromatic, carminative, anti-tussive, emmenagogue, litholytic, sedative, stimulant, stomachic, vermifuge, tonic and antibacterial. This paper provides a review of medicinal uses and various updated pharmacological properties of C. rotundus rhizome. The update is essential for developing the traditional...
