Raphanus sativus commonly known as radish is cultivated as a crop and having various medicinal uses. It is cultivated all over the world as an edible root vegetable. The present study deals with the pharmacognostic, preliminary phytochemical investigation of Raphanus sativus, Linn. belonging to family Cruciferae. In this, pharmacognostic studies are concerned for the determination of physicochemical parameters like ash values, extractive values, and loss on drying, fluorescence analysis also the macroscopic and microscopic evaluation carried out. The leaves were subjected to successive soxhlation using petroleum ether, ethyl acetate, alcohol, and water. The extracts thus obtained were studied for preliminary phytochemical investigation for detection of the presence of various chemical constituents like alkaloids, glycosides, steroids, tannins, saponins, fats and oils, flavonoids,...

Vitamin C, also known as ascorbic acid, is a water-soluble antioxidant vitamin having important nutritional and health benefits. Adequate consumption of fruits, vegetables and their juices with high vitamin C content and antioxidant capacity result in improved health, reduced risk of chronic diseases, optimal nutrition and general well-being. Thus, it is essential that vitamin C content in food items, intended to provide its supplement, is determined and its amount stated on labels of packages. The objective of the present study was to determine and compare the vitamin C content of fresh and commercial juices made from mango and orange. Fruits and packed juices were purchased from the local market of Mekelle city, Ethiopia. Iodine titration method was employed to determine the vitamin C content of test sample juices. Results showed that the amount of vitamin C was more in fresh juice than the corresponding packed juice in both mango and orange. For the fresh juices, the amount of vitamin C was more in orange than in mango while for...

Curcuma amada and Curcuma aeruginosa are economically and medicinally very important species in India. Both of the species look similar in morphological nature. In the present study, an effort has been made to work out the identifying characters and detailed comparative account of both species for ready identification of the entire plant, live or in the herbarium and also the discrimination of drugs made from the rhizome of both species. The studies of both species revealed the presence of entire major compounds like alkaloids, flavonoids, glycosides, phenols, and tannins, saponins etc. The macroscopic and microscopic studies of both species expressed difference. The activities of the powder with different chemicals and fluorescent studies showed characteristic...

In this study, the phytochemical analysis took place for solvent extracts (petroleum ether, chloroform) and essential oils. Maceration method and hydrodistillation were used for the solvent extraction and essential oil extraction respectively. Solvent extract was studied for phytochemical analysis and antibacterial activities. The antibacterial activity of a solvent extract of Lantana camara L. leaf was investigated against Pseudomonas aeruginosa (gram -), E. coli (gram-) and Staphylococcus aureus (gram+). The paper disk agar diffusion methods tested the antibacterial activity inhibition of growth. Phytochemical analysis showed that solvent extract (petroleum ether, chloroform) contains more constituents than the essential oil of Lantana camara L. leaf. This difference might come from the volatile constituents and non-volatile constituents of this plant. Solvent extracts gave a positive test for most phytochemical analysis, but the oil gave a positive test only for carbohydrate and terpenoids. Staphylococcus aureus was highly susceptible to the petroleum extract than chloroform extract; with a zone of inhibition from 14.17 ± 0.29 mm to17.7 ± 0.2 mm. Pseudomonas aeruginosa was less susceptible...

A phytotherapeutic approach to modern drug development can provide many invaluable drugs from traditional medicinal plants. Medicinal plants have been considered as an important therapeutic aid for alleviating ailment of humankind. Numerous plants and polyherbal formulations are used for the treatment of liver diseases. This present investigation was aimed at assessing the hepatoprotective activity of aqueous, ethanol and acetone extract of Sesbania grandiflora leaves against carbon tetrachloride (CCl4) induced liver damage in Albino rats. Silymarin as a standard drug for comparing the activity. The activity was assessed by comparing the biochemical parameters in serum levels such as serum glutamate pyruvate transaminase, serum glutamate oxalate transaminase, total bilirubin, alkaline phosphatase of plant extracts treated group with carbon tetrachloride treated animals. Results showed, ethanolic extract treated group showed highly significant activity (P<0.001), whereas aqueous extract treated group has shown the significant (P<0.01) action but less compared with ethanolic extract, acetone treated group showed moderate action. Plant extracts restore biochemical enzymes and bring down to normal as compared to standard drug silymarin....
