Calotropis gigantea Linn. white (Asclepiadaceae), it is a weed plant commonly known as giant milkweed. It has one of the important traditional medicines to treat various ailments. The basic aim of this study to Calotropis gigantea is one such plant. In this review, the systematic position, introduction about the plant, morphological study, phytochemistry and the economical values of the Calotropis gigantea are discussed. Calotropis gigantea is a glabrous or hoary, laticiferous shrubs or small trees, it also known as “the swallow-wort or milkweed.” Calotropis is used as a traditional medicinal plant. C. gigantea contains chemical constituents are cardenolides, flavonoids, terpenes, pregnanes, and nonprotein amino acid. The latex, leaves, flowers, bark, the root is also used as caustic, acrid, expectorant, depilatory, antihelmintic, useful in leprosy scabies ringworm of the scalp, piles, eruptions on the body, asthma, enlargement of spleen and liver, dropsy applied to painful joint swellings. This review gives a brief idea about its phytochemistry and pharmacological...

Growing awareness and interest towards traditional health care system coupled with phenomenal increase in demand and trade of medicinal plant has caused severe threat to the very existence of medicinal plants, which can be gauged from the fact that a number of important medicinal plants are becoming threatened or extinct, and an increasing number of species are being substituted in herbal preparations. There is, therefore, a need to strike a balance between conservation and use. It is imperative to evolve viable strategies to conserve the surviving populations and their genetic resource of critically important species to avoid further loss. Further, spurt demand for herbal drugs has led to renewed interest in screening plants for novel biologically active compounds particularly to combat such ailments which have defied synthetics drugs. The herbal sector is under constant pressure to develop and deliver effective natural drugs. Phytochemical and pharmacological investigations have led to the isolation and characterization of a significant number of active molecules with versatile therapeutic efficacy. Biotechnology has emerged as the...

Extracts from leaves, stems and flower buds of Myrciaria glazioviana were analyzed for their antioxidant and anticholinesterase activity. The methanolic extracts showed the best results in reducing power (623.52 – 806.15 mg AA/g of extract), DPPH radical scavenging (IC50 = 9.77 – 14.06µg/mL) and lipid peroxidation inhibition activity (21.30 – 66.80 %). These data were correlated to the total phenolic content (270.19 – 351.01 mg GA/g of extract). The dichloromethane extract of leaves exhibited a higher anticholinesterase potential (IC50=249.25 µg/mL). Furthermore, the chemical composition of the essential oils from leaves collected in all seasons of the year was analyzed by GC-MS and GC-FID. Only sesquiterpenes were identified in all essential oils, and non-functionalized sesquiterpenes comprised the major fractions (from 66.8 to 79.3 %). An increase in non-functionalized compounds was observed in the warmer seasons. Germacrene B was the major compound in all seasons (from 26.8 to 30.1 %). In winter and autumn, high contents of germacrene D (10.2 and 10.0 %, respectively) and α-cadinol (12.1 and 12.0 %, respectively)...

People, who have visits to high altitudes, do experience a certain type of health problems as they transit to different altitude ranges. With ascend to high altitude, various kinds of acute and chronic physiological changes occur which influence all system of the human body. These problems although have temporary manifestations, arising due to maladjustment of the body to abrupt altitudinal changes in oxygen, atmospheric pressure, and gravity but sometimes can be life-threatening. Often it has been found that these symptoms are confused with other complications of the body. Present review mention different type of altitude health problems, their symptoms, herbal and synthetic drugs that is helpful in these...

Aristolochia bracteolate is a small, glabrous shrub occurring in India. It belongs to the family Aristolochiaceae. The whole plant is used in various ailments like abortifacient, alterative, anthelmintic, antiperiodic, emmenagogue and purgative. The stem and root are having aristolochia acid (Alkaloid). The leaves and roots are used to rid the body of Guinea worm (a parasitic infection caused by a nematode). In present study was macroscopical, microscopy, physiochemical parameters (extractive values, crude fiber content, ash values, foreign organic matter), fluorescent analysis, plant cell inclusions reported. The ethanolic plant extraction was carried out by using a soxhlet apparatus. The extract was screened for phytochemical properties by using a color reaction...
