Background: Two primary species of Mimusops are Mimusops elengi and Mimusops hexandra. Leaves of both species are traditionally used in several ailments. However, it is difficult to distinguish the leaves of the species. Objectives: The present investigation deals with the comparative pharmacognostical study of the leaves of the two species and establishment of its quality parameters. Methods: Detailed morphological and qualitative as well as quantitative microscopic study was carried out. This was followed by phytochemical screening and estimation of tannins in the two species. Results: The important diagnostic feature of powder of both leaves include pericyclic fibers, rosette and prism shape calcium oxalate crystals and resinous matter. The leaves show significant difference in their quantitative microscopic parameters as well as their tannin content. Conclusion: The present work can serve as a useful tool in the identification, authentication and standardization of the plant material and distinguishing the two species from each...

Oxygen is an element obligatory for life. Biological combustion produces harmful intermediates called free radicals. Free radicals are continuously produced by the body’s aerobic life and our metabolism. Antioxidants are the substances, which act against oxidative compounds. Under normal conditions the body’s antioxidants convert ROS to prevent the over production of free radicals. Recently, natural foods and food derived antioxidants such as vitamins and phenolic phytochemicals, have received growing attention, because they are known to function as chemo preventive agents against oxidative damage and are considered beneficial for human health. The present study was conducted to compare the antioxidant activity of fresh and dry rhizomes of Curcuma zedoaria. The methanol extract of both the rhizomes showed good radical scavenging...

Background: Black tea is rich in polyphenols which are antioxidants. The most abundant polyphenolic compounds are flavonols and catechins. Black tea antioxidants showed protective actions against chronic diseases like cardiovascular diseases due to their antioxidant action. Objective: The present study was conducted to evaluate the cardioprotective effects of Camellia sinensis on isoproterenol induced myocardial infarction in Wistar albino rats. Myocardial infarction (MI) is a condition in which a part of the heart muscle suddenly loses its blood supply, so the myocardium gets destructed and becomes ischemic. Camellia sinensis is a species of plant from which leaves and leaf buds are taken to produce tea. Myocardial infarction was induced by subcutaneous administration of Isoproterenol. Isoproterenol shows positive inotropic and chronotropic effects on heart. Oxidative products of drug cause cytotoxicity and myocardial damage. Methods: Wistar albino rats were divided into 8 groups, each group containing 8 rats. The following treatment was given for 21 days. Group 1: NS 1mg/kg (orally). Group 2: NS+ISO (85 mg/kg, s.c.). Group 3: BTE 1 (4mg/kg,...

Endophytic fungi residing inside the medicinal plants are of gaining importance for their bioactive compounds. This present study is undertaken to isolate and identify the potential endophytic fungi from Moringa oleifera, a traditional medicinal plant. A total of 24 segments each 12 from leaf and stem were collected, surface sterilized and was inoculated on to Sabouraud Dextrose Agar (SDA) plates. Based on the macroscopic & microscopic features the fungal isolates were identified as Alternaria spp., Aspergillus spp. Bipolaris spp., Exosphiala spp., Nigrospora spp., and Penicillium spp. Many unidentified sterile mycelia forms were also found which were grouped under the class mycelial sterilia. The Colonization Frequency (CF) and Endophytic Infection Rate (EIR) were observed as 91.66% and 45.83% respectively. The results of this study suggest that traditional medicinal plants are a rich and reliable source of novel endophytic fungi. Further studies are required with regard to the screening of these endophytic fungi for the production of novel bioactive compounds which are medically important in the treatment of...
