Lipid dosage forms are attractive delivery systems for hydrophobic drug molecules. Emulsion is one of the popular system since many decades. Pharmaceutical applications of emulsions widened especially after micro and nano-emulsion emergence. This paper is an attempt to summarise comparative aspects like definition, theories, types, methods of preparations, advantages, disadvantages and methods of analysis of emulsion, micro-emulsion and nano-emulsion.

Silver nanoparticles (SNPs), owing to their wide range of biomedical applications, have recently attracted remarkable interest for use in cancer nanomedicine. The present research work investigated the anticancer activity of phytosynthesized SNPs against human cancer cell lines. Phytosynthesis of SNPs was achieved by using an aqueous extract of Salacia chinensis (SC) bark as a green source to reduce silver nitrate to silver nanoparticles. Characterization of synthesized nanoparticles demonstrated a UV–visible peak at 443 nm, ζ-potential (zetasizer) of −25.6 ± 0.34 and particle size (transmission electron microscopy analysis) in the range of 40–80 nm, which validates formation of stable silver nanoparticles. The absence of cytotoxicity against normal human fibroblasts and blood erythrocytes confirms the biocompatible nature of green synthesized SNPs. In vitro anticancer assay demonstrated IC50 values of 6.31, 4.002, 5.228, 8.452, 14.37, 7.46, and 6.55 μg/mL against liver (Hep G2), lungs (L-132), pancreas (MIA-Pa-Ca-2), breast (MDA-MB-231), oral (KB cells), prostate (PC-3), and cervical (HeLa) cancer cell lines respectively, which confirms its potent anticancer action. The results of the present study give an experimental proof that the SC mediated green synthesized SNPs could serve as a promising anticancer agent to overcome limitations of existing conventional cancer chemotherapeutics.

Thus present research work deals with the development and evaluation of topical photo protective formulation, containing antioxidant, wound healing, anti-inflammatory and rather photo protective poly phenols like curcumin, quercetin, resveratrol and safranal. The present research work provides stable natural photo protective formulation with antioxidant potential, high SPF and more important uniform UVA/UVB protection.

Sunlight despite of source of life and energy creating major health challenges like sunburn, pigmentation, wrinkles, dermatitis, urticaria, ageing, immune-suppression and number of skin cancers too. Sun protective clothes and or sunglasses provide insufficient and less convenient approach to get rid of all these health hazards. So sunscreen protection is popular mean among various regions of world. Present article have summarize types and classification, regulations, terminologies, evaluation methods, labeling, dosage and controversies of sunscreens. Natural chemical classes like phenolics (tannins, flavonoids), carotenoids, vitamins, oils are also discussed.

Background:The present communication deals with the identification and characterization of bioactive principles from the roots of Chlorophytum borivilianum.Method:Methanolic extract and its fractions were used to isolate different phytoconstituents. The structures of isolated compounds were characterized and elucidated with chemical and spectroscopic techniques such as Infra Red, Nuclear Mass Resonace and Mass spectroscopy experiments. Fatty acids were characterized by GC-MS analysis.Result:Three Fatty acids were isolated and confirmed. One sterol stigmasterol was isolated. One new saponin named as Chlorophytoside-I (3β, 5α, 22R, 25R)-26-(β-D-glucopyranosyloxy)-22-hydroxy-furostan-12-one-3 yl O-β-D-galactopyranosyl (1-4) glucopyranoside was isolated.Conclusion:The roots of Chlorophytum borivilianum contain three important fatty acids, common sterol stigmasterol and one furostanol saponins.
