Green nanotechnology incorporates the principles of green chemistry and green engineering to fabricate innocuous and eco-friendly nano assemblies to combat the problems affecting human health or the environment. As nanoparticles inch closer to being fully deployed at the clinical level, some of the recent advances in the applications of nanoparticles in medicine are reviewed. From imaging and diagnostics to therapy and treatment, a variety of nanoparticles are presented along with their physical and optical properties to be used in a diverse array of medical applications. While other reviews are tailored to specific applications or to single nanoparticle types, this review aims to offer a more widespread view on visualization, diagnosis, and treatment of disease with various types of nanoparticles.">

Herbal medicines are promising alternatives over modern synthetic drugs. They serve as a huge supply of diverse phytoconstituents exhibiting various pharmacological property. One of the most significant plant is Gliricidia sepium (Jacq.) Kunth. ex. Walp. as it acts as a storehouse for powerful bioactive substances like saponins, flavonoids, glycosides, volatile oils and other substances that have been extracted from different portions of the plant. Due to its many traditional uses, such as treating coughs, asthma, urticaria, rashes, burns, scabies, dermatitis, surgical site infections, functioning as an anti-pruritic action on the skin, and treating bacterial and protozoal infections, Gliricidia sepium is the subject of extensive research. It is essential to evaluate the pharmacognostical characteristic of the plant before its use in the field of research and also in pharmaceutical formulation. Pharmacognostical study mainly covers the macroscopic and microscopic features of the leaves mainly transverse section and powder microscopy and revealed the presence of epidermal cells, palisade cells, simple non glandular trichomes etc. The phytochemical constituents were determined by both qualitative and quantitative methods. TLC profile studies of the ethanolic extracts of the Gliricidia sepium were performed. Preliminary phytochemical screening showed the presence of various phytoconstituents like alkaloids, glycosides, tannins, flavonoids, steroid, phenols, carbohydrate and absence of proteins and amino acids. Quantitative analysis revealed that the leaf extract contains significant amount of phenolic and flavonoid compounds. The current study provides information about the plant and serve as an analytical tool for proper identification and standardization.">

Nyctanthes arbor-tristis Linn. (NAT) is documented Indian ancient plant that has high medicative worth in Ayurveda. It’s popularly called Parijat or Harsingar. Each part of the plant has some medicinal value and is used for various pharmacological actions. The present study deals with the qualitative and quantitative microscopic analysis of the leaves and establishment of its quality parameters, including physicochemical and phytochemical analysis. The phytochemical analysis of plant revealed presence of flavonoids, tannins, saponins, glycosides, alkaloids, steroids and phenolic compounds which are responsible for the pharmacological actions of the plant. The pharmacognostic characters were determined in terms of macroscopy, microscopy and powder microscopy of Nyctanthes arbor-tristis leaves">">">">

Canna is an ornamental and therapeutic plant belonging to the Cannacea family. It has several varieties that differ in flower color. This study compares the anti-free radical and the antioxidant capacity of the aerial parts (flowers, leaves and stems) of Canna indica and Canna flava. Hydroethanolic extracts were obtained by maceration. Phytochemical screening was carried out using precipitation reaction and colorimetry methods. Total phenol content was determined using the Folin-Ciocalteu reagent and flavonoid content by AlCl₃. Antioxidant activity was assessed using DPPH and FRAP reagents. The results show that the extracts contain flavonoids, phenols, cardiac glycosides, terpenes, terpenoids and quinones. Determination of total phenol content revealed that the extract from indica flowers contained a significant quantity, i.e. 196.7 EqAG/g ES. For the flava variety, leaf extract provided the highest total phenol content, at 142.17 EqAG/g. The highest levels of total flavonoids were found in indica flower and flava leaf extracts, at 456.57 and 316.87 EqQ/g ES respectively. This study reveals that flower and leaf extracts from both varieties were preferable for their good anti-free radical and antioxidant capacities. 

In this present study, to formulate topical herbal face serum prepared by Simarouba glauca leaves and evaluate their anti-oxidant depigmentation activity. The face serum were prepared using the ethyl acetate extract of Simarouba glauca leaves. Prepared face serum were subjected to various evaluation parameters such as physicochemical parameters, pH, viscosity, spreadability, homogeneity, grittiness, extrudability, skin irritation, stability study and anti- oxidant depigmentation activity. A topical face serum was successfully formulated containing bioactive ethylacetate extract of Simarouba glauca leaves. The face serum was found to be very effective as anti-oxidant depigmentation formulation. ">
