Cell wall polysaccharides have been of great importance to society and mankind over the years. In the present study Cell wall polysaccharides were extracted from different stages viz- Immature green, mature green and ripe stages of Prunus armaniaca Linn. A decrease in the yield of pectin was observed during ripening.The pectin Extracted from various stages of fruit ripening was further analysed for in vitro antioxidant activity by different assays. During the ripening of fruit it was seen than the pectin extracted showed increase in total antioxidant, reducing power and scavenging of hydrogen peroxide which can be related to galacturonic acid content by further studies and can be explored as a novel potent...

The leaves of Paederia foetida Linn. (P. foetida) are commonly known as skunk vine or Chinese fever vine, are used for various ailments medicinally throughout Asia and other tropical parts of the world by traditional healers. The plant is mainly used for arthritis and rheumatic disorders. The whole plant shows tonic, astringent and antiphlogistic actions and has been used in tenesmus. This present work presents a detailed pharmacognostical study of the leaf of the crude drug P. foetida. The samples were studied using procedures of light, confocal microscopy, WHO recommended physico-chemical determinations and authentic phytochemical procedures. The physico-chemical, morphological and histological parameters presented in this study may be proposed as parameters to establish the authenticity of P. foetida and may possibly help to differentiate the drug from its...

Plants containing bioactive substances have increasingly become the object of research studies, opening alternative paths for therapeutic treatments or revealing substances that could later be explored and synthesized to produce pharmaceutical, cosmetic and agrochemical formulations. Alpinia purpurata have strong effect on H2O2 induced oxidative damages. The extract of Alpinia purpurata showed a higher antioxidant activity. The results suggest that the plants extract prevent oxidative damage in normal cells probably because of their antioxidant characteristics.“Phytochemicals or phytoconstituents” are becomingly known for their antioxidant...

Vismia guianensis is a plant species of high occurrence in the Amazon and northeastern Brazil, which has been studied lately, because of its antimicrobial and anticancer properties.In order to make an herbal medicine, National Agency for Sanitary Surveillance of Brazil, recommends the production of a drug and plant extracts analysis report indicating: method, specifications and results obtained. The drug was characterized by particle size, amount of water and the total ash content; and plant extract through its density, pH and dry residue. The quantification of total anthraquinones and method validation was done by UV-VIS spectroscopy. The drug in this study produced a coarse powder whose determination of water is within the acceptable limits and the total ash content was 1.64%. The extractive solution showed a low pH, density of 0.89 mg/mL and 9.5% on yields from solids. HPLC found that the EtOAc fraction of the plant extract is consisted of phenolic compounds and anthraquinones. And the method of quantification of total anthraquinones, using emodin as external standard, was validated...

ABSTRACT Study objective: To investigate the use of antihypertensive drugs in hypertensive patients and to identify whether such pattern of prescription is appropriate in accordance with international guidelines for management of hypertension. Methods: This was a prospective analysis. A prescription based survey among patients with established hypertension was conducted at the Medicine Out-Patient Department of University Teaching Hospital in South Delhi, India. Data were collected from patients’ medical records as well as patients’ interviews. Results: A total of 192 hypertensive patients fulfilled the criteria for inclusion in the study analysis. Combination therapy was used more commonly than monotherapy (54.6% vs 45.4). Among the monotherapy category, the various classes of drugs used were as follows: beta- blockers (28.8%), diuretics (24.1%), calcium channel blockers (21.8%), ACE inhibitors (18.4%), angiotensin II receptor blockers (5.7%) and α 1- blocker (1.1%). With respect to overall utilization pattern, diuretics (42.2%) were the most frequently prescribed class, beta- blockers (41.2%) ranked second followed by calcium channel blockers (39.1%), ACE inhibitors (26.0%), angiotensin II receptor blockers (23.4%)...
