PRELIMINARY INVESTIGATION OF PHYTOCHEMICALS OF SAUSSUREA OBVALLATA (BRAHM KAMAL) AND PITTOSPORUM ERIOCARPUM (AGNI): TWO ENDANGERED MEDICINAL PLANT SPECIES OF UTTARAKHAND
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 als...
Areca catechu has been in use as a social drug from the time immemorial and usually chewed by at least 10% of the world’s population. Areca catechu commonly known as supari consists of dried ripe nuts and belongs to the family Palmae which is cultivated in tropical India, Sri Lanka, Malaysia, South China, the East Indies, the Philippines Islands and part of East Africa (including Zanzibar and Ta...
PHYTOCHEMICAL SCREENING AND EVALUATION OF VARIOUS EXTRACTS OF LAGENERIA SICERARIA FOR ANTIOXIDANT ACTIVITY
Lagenaria siceraria was commonly known as Bottle gourd Syn. Doodhi, Syn. Lauki (Hindi) Kadoo (Marathi) which is official in Ayurvedic Pharmacopoeia. Preliminary phytochemical screening of the crude extracts revealed the presence of carbohydrates, proteins, etc. and secondary metabolites like saponins, glycosides, alkaloids, etc. in all the extracts but tannins were found absent in ethanolic and pe...
Rhizome of Kaempferia galanga (Family: Zingiberaceae) has been investigated for isolation of secondary metabolites and evaluation of bioactivities. Two cinnamic acid derivatives, Ethyl p-methoxycinnamate (KG-2) and 4-methoxy cinnamic acid (KG-9) have been isolated from the chloroform fraction of the methanolic extract of the rhizome of K. galanga using chromatographic analysis. Structures of these...
Rhizoma Curcumae longae is the dried rhizome of Curcuma longa L. (Zingiberaceae), commonly known as turmeric, has a long history of traditional uses for culinary purposes as a spice and as a food colorant. This study was aimed at establishing the microscopic identification of different commercial samples and developing parameters for discriminating turmeric powders. In this study, fifteen sample...
Plants have been the basis of many traditional medicines throughout the world for thousands of years and have continued to provide new remedies to mankind. They are one of the most abundant sources of bioactive compounds. The genus Passiflora L. comprises about 520 species of dicotyledonous plants in the family Passifloraceae. Passiflora incarnata and P. alata, also commonly known as passion flowe...
MORTALITY AND REPELLENT ACTIVITY OF CLERODENDRUM VISCOSUM VENT. (VERBENACEAE) AGAINST SITOPHILUS ORYZAE (COLEOPTERA: CURCULIONIDAE)
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 activ...
The genus Ruellia L. is sometimes called Dipteracanthus, it comprises about 150 species native to tropical and temperate North and South America. In this review, the literature data on phytochemical and biological investigations of the genus Ruellia are compiled. The well-recognized groups of secondary metabolites were flavonoids, lignans, coumarins, alkaloids, triterpenes, sterols, phenolic gly...
The proliferation of β-cells is the main contributor to the mass cell maintenance in the pancreatic islets. In our earlier work the suppression of β-cell growth by aggregated peptide hormone of the pancreas, amylin, has been proved. The in-vitro protection of the cells from aggregated amylin-associated death by several plant extracts and their constituents has been shown. In the present work, ...
ANTIOXIDANT ACTIVITY AND PHYTOCHEMICAL ANALYSIS OF FRACTIONATED LEAF EXTRACTS OF CATHARANTHUS ROSEUS
Antioxidant effectiveness of indigenous medicinal plant C. roseus leaves extracts and fractions with solvents of different polarity (ethanol, methanol, acetone, hexane, butanol, and water) were assessed for DPPH radical scavenging activity. The C. roseus extracts and fractions contained appreciable levels of the antioxidant activities of leaves of C. roseus at various concentrations. The leaves of...
