The poisonous and medicinal plants are found in a natural ecosystem. The Arisaema murrayi (Hook) is an herb which is highly poisonous. It is found in the hilly region of Mumbai area. Livestock, cattle and human beings do not consume fruits and tubers of the plant, so the forensic study of this plant is carried out. Aqueous extracts of tuber 2%, 4% and 6% feed orally to Swiss albino mice. Present investigation study includes the histopathology, phyto-chemistry and quantitative microscopy. It is observed that liver, intestine, and kidney were severally damaged by using the Arisaema murrayi (Hook) plant parts. The forensic study proved that these organs were damaged by the poison of Arisaema murrayi (Hook) plant of the...

World Health Organization appreciated the importance of medicinal plants for public health care in developing nations. The tribal region of Ghoti Taluka-Igatpuri, district-Nashik has various medicinal plant species to cure the ailments. This medicinal plant species are found in the Kokani region of Ghoti and Igatpuri. The pharmacognostic study of these medicinal plants used in ghoti tribal region can help to discover new drugs to cure various ailments provided the data given is scientifically evaluated. The present study highlights the pharmacognostical as well as phytochemical studies including parameters such as macroscopic, microscopic characters, physical evaluation and preliminary phytochemical studies of some medicinal plants used in Ghoti region of Nashik district. These observations will help in the pharmacognostical identification and standardization of the drug in the crude form and also distinguish the drug from its...

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...
