Microencapsulation: A Review

Abstract: Microencapsulation is the process of surrounding or enveloping one substance within another substance on a very small scale, yielding capsules ranging from less than one micron to several hundred microns in size. The encapsulation efficiency of the microparticles or microsphere or microcapsule depends upon different factors like concentration of the polymer, solubility of polymer in solvent, rate of solvent removal, solubility of organic solvent in water etc. Microencapsulation may be achieved by a myriad of techniques. Substances may be microencapsulated with the intention that the core material be confined within capsule walls for a specific period of time. Alternatively, core materials may be encapsulated so that the core material will be released either gradually through the capsule walls, known as controlled release or diffusion, or when external conditions trigger the capsule walls to rupture, melt, or dissolve. This article is a review of microencapsulation and materials involved in it, morphology of microcapsules, microencapsulation technologies, purposes of microencapsulation, and benefits of microencapsulation, release mechanisms, and application fields, with special emphasis on microencapsulated additives in building construction materials

Review on nutritional, medicinal and pharmacological properties of guava (PSIDIUM GUAJAVA LINN.)

Abstract: Guava (Psidium guajava Linn.) commonly known for its food and nutritional values throughout the world. The medicinal properties of guava fruit, leaf and other parts of the plant are also well known in traditional system of medicine. Since, each part of guava tree possesses economic value; it is grown on commercial scale. Guava plant is considerable process has been achieved regarding the biological activity and medicinal application of guava and the fruit considered as poor man apple of tropics. The guava plant parts are used for the development of various industrial and pharmaceutical products. In the present review, nutritional value of guava fruit and medicinal properties its various parts have been discussed to provide collective information on its multi purpose commercial values.

Impact of solvent extraction type on total polyphenols content and biological activity from tamarix aphylla (l.) Karst.

Abstract: Secondary metabolites of an arabo-saharan tree Tamarix aphylla (L.) Karst. Were extracted from dry powdered leaves with different solvents: aqueous methanol; aqueous ethanol, aqueous acetone and distilled water. Total phenolic content of the four extracts were determined by Folin Ciocalteu method and their antioxidant activity was assayed through in vitro radical scavenging activity using DPPH assay. The results showed that mixture water-methanol was better than water-ethanol, wateracetone and water for extraction bioactive compounds in particularly total polyphenols from Tamarix aphylla leaves. The average total phenol content of aqueous methanol extract was 262.26mg GAE/100g dry weight lyophilized extract. However, all extracts were free-radical inhibitors but aqueous acetone extract was more potent than aqueous ethanol extract and two others extracts. In order of effectiveness (EC50), the potent inhibitors were from water-acetone extract (0.080mg/ml) > water-ethanol extract (0.140mg/ml)>water extract (0.173mg/ml)> Water-methanol (0.911mg/ml).

Zingiber officinale: a natural gold

Abstract: Ginger, (Zingiber officinale Roscoe, Zingiberacae) is one of the important medicinal plant which naturally occurs in various country like India, China, South East Asia, West Indies, Mexico and other parts of the world. This natural gold has been consumed worldwide as a spice and flavoring agent from the ancient time. Ginger plants are generally 1-3 ft. in height and having different chemical constituents like Amaldehyde, Gingerol, Shogaol, and Paradol etc. It has some tremendous beneficial effect to human body to cure various types of diseases. Ginger bears an enormous number of pharmacological activities among those, Neuro-protective activity and activity against colon cancer have facilitated the extent of further research for finding out less toxic and more potent drugs for the better treatment of those diseases. This review will facilitate to gain all about the past scientific research and the necessary information about the enormous pharmacological activities of ginger which will insist researchers for future research to protect human beings from several types of diseases and may serves as a natural gold for the promotion of mankind.

Potential Applications of Nanoparticles

Abstract: Nanoparticles (NP) are defined as particles with a diameter smaller than 100 nm, are increasingly used in different applications, including drug carrier s ystems and to pass organ barriers such as the blood -brain barrier. Because of their unique properties Nanocry stals (quantum dots) and other nanoparticles (gold colloids, nanobars, dendrimers and nanoshells) have been receiving a lot of attention for potential use in Thera peutics, Bioengineering and therapeutics drug discovery. In this review potential use of these Nanocrystals and Nanoparticles in various important areas has been d iscussed. Special properties of these nanoparticles may offer new advancement in drug discovery.
