The aims of this study to evaluate the pulp and paper-making properties of Caesalpinia decapetela based on proximate chemical composition, fiber morphology, pulping, bleaching, and physical test of the final product. The results proximate chemical analysis showed that C. decapetela has holocellulose content of 78.14±0.1 % and lignin content 18.0±0.04 %. Fiber morphology revealed that the fibers were 0.708 mm long, 18.63 μm width, and have 5.1 μm cell wall thicknesses. Kraft pulping of C. decapetale, was performed at different active alkali (5 %, 10 %, 15 %, 20 % and 25 %) and temperature (150, 160 and 170 °C), keeping the sulphidity 25 % constant. The pulp maximum yield 44.1 % was obtained at active alkali content of 15 %, temperature 160 °C, and cooking time 90 minutes. The effect of ...

The percentage yield of the extracts wares calculated. The extract was used to analyze phytoconstituents qualitatively, and total phenolic and flavonoid content were estimated. In another study, already purified methanolic extract of R. arboreum leaves, namely cytoplasmic male sterility (CMS-3) (kaempferol), RAM fr2, and transcranial magnetic stimulation (TMS-10) (ursolic acid) was used to evaluate ...

Methods: The plant material was collected from lower Himalayan region of Uttarakhand in India. The essential oils from three different aerial parts were analyzed by GC-MS. Antioxidant activity, phenolic assay, and various pharmacological activities were determined by using existing methods which are generally practiced widely. Results: Over 51, 53, and 40 compounds were identified in C. macrophylla leaves essential oil (CMLEO), C. macrophylla pre mature seeds and fruits essential oil (CMEO-I) and C.macrophylla mature seeds and fruits essential oil (CMEO-II), respectively. These oils differ in relative contents of major compounds viz; β-selinene (37.51% in CMLEO, 44.66% in CMEO-I and 57.01% in CMEO-II), phyllocladene (9.76% in CMLEO, 5.80% in CMEO-I and 12.38% in CMEO-II), caryophelline oxide (7.34% in CMLEO, 8.74% in CMEO-I and 5.0% in CMEO-II), 9E-epi-cary...

Cannaceae was collected, dried and extracted with different solvents. Different test were performed for the presence of different phytochemicals. The antimicrobial activity was determined by agar well-diffusion method. The extracts were evaluated for antidiabetic activity by using alpha-amylase and alpha-glucosidase enzyme inhibition method.Results and conclusion: The findings of the present study indicate that C. indica extracts contain secondary metabolites which have potent antimicrobial and antidiabetic activities comparable to standard drugs. This information may help to develop potent bioactive compound(s) in the pharmaceutical industry for the development of drugs.

Nearly all cultures and civilizations from ancient times to the present day have used herbal medicines which are medicinal sources to cure infections. 1 Medicinal plants have many advantages to the health of individual and the communities. The medicinal advantages of some plants fall in the presence of some chemical compounds that produce fixed physiological actions in the human body. Some of these biologically active ingredients are tannins, flavonoids, alkaloids and phenolic compounds. 2 Bioactive ingredients of medicinal plants can be identified through extraction and characterization techniques. The mode of action of the plant extracts producing the therapeutic effect can also be better investigated, if the active ingredients are characterized and understood which have led to a continuous search for potent antimicrobial agents. Natural products are believed to play vital roles in the physiology and ecology of the plants that produce them, particularly as defense elements against pests and pathogens or as attractants for beneficial organisms such as insect pollinators. Because of their ABSTRACT Background: For thousands of years, several people depend on traditional medicines from flowers, bark, leaves and fruits of plants. Sweet Basil (Ocimum basilicum L.) is a medicinal herb which belongs to the family of Labiatae and it is the most abundant of the genus Ocimum. The present study aimed to isolate pure compounds from chloroform/methanol (1:1) crude extract of the leaves of O. basilicum herb and characterize them using infra-red (IR) and nuclear magnetic resonance (NMR) spectroscopic techniques. Methods: The sample of powdered leaves of O. basilicum was extracted using a mixture of chloroform and methanol (1:1) and the crude extract was investigated for its chemical composition using spectroscopic techniques. Results: Only one fraction designated as O. basilicum-14 (OB-14) displayed a single spot on TLC plate. Results showed that two isomeric compounds named (1-(2-vinylcyclohexa-1,4-dienyl) propan-2-ol and 2-(2-vinylcyclohexa-1,5-dienyl) propan-1-ol) were isolated as a mixtures using column chromatography over silica gel. The structures of these compounds were identified using IR and one dimensional NMR spectroscopic techniques such as proton NMR (1 H NMR), carbon-13 NMR (13 C NMR) and distortionless enhancement by polarization transfer (DEPT). Conclusions: So, more compounds can be isolated from the plant using different chromatographic techniques.
