In this study, the green synthesis of silver nanoparticles (AgNPs) was performed by using Moringa oleifera leaf extract as a reducing and stabilizing agent. The synthesized AgNPs were subjected to different characterization techniques. UV-visible spectroscopy confirmed the surface plasmon resonance band in the range of 400–450 nm, and zeta analysis revealed that the synthesized AgNPs ranged 4–30 nm in size. Scanning electron microscopy depicted tiny fused rectangular segments and the crystalline nature of the synthesized AgNPs was confirmed using X-ray diffraction. Energy dispersive X-ray (EDX) detector confirmed the presence of metallic silver ions. Fourier-transform infrared analysis revealed the presence of phenols as main reducing agents in the plant extract. Foliar application of different concentrations (25, 50, 75, and 100 ppm) of AgNPs was applied ...

These chemicals are produced under specific abiotic stresses and pathogenic attacks, therefore impart survival tactics to plants. A large number of such compounds and their biosynthetic pathways have been discovered so far from plant kingdom. Owing to their diverse biological and physio-chemical properties secondary metabolites are of great interest to man and impart uses as drugs, oils, waxes, perfumes, flavoring agents, dyes and many other commercially important materials. Secondary metabolites led to the emergence of a new research discipline of plant metabolomics, committed to detection and identification of biosynthetic pathways of these compounds, their structural elucidation and applications. The review provides an insight into the diversity of plant seco...

The synthesis, characterisation and applications of metallic nanoparticles (MNPs) have become an important branch of nanotechnology. In the current study, MNPs were synthesised through polyols process and applied in vitro to study their effect on medicinally important plant : Artemisia absinthium. The current study strives to check the effect of MNPs, i.e., Ag, Cu and Au on seed germination, root and shoot length, seedling vigour index (SVI) and biochemical profiling in A. absinthium. The seeds were inoculated on MS medium supplemented with various combinations of MNPs suspension. The seed germination was greatly influenced upon the application of MNPs and was recorded highest for the silver nanoparticles (AgNPs) suspensions. The best result for seed germination (98.6%) was obtained in MS medium supplemented with AgNPs as compared to control (92.9%) and other nanoparticles, i.e., copper (6...

Introduction Polygonatum (King Solomon's-seal, Solomon's seal) is a genus of erect or decumbent perennial herbs belonging to the family Liliaceae representing about 57 species in the world. This genus is mostly distributed in the temperate regions of the northern hemisphere, most concentrated in the Himalayas. It also occurs in East Asia, where it is found mostly in China and Japan where 40 species of this genus were found[1]. In addition to this, they are also found in India,

(Blanco)]. Nucellus tissues were cultured on MS medium supplemented with different concentrations and combinations of auxins, cytokinins and malt extract for primary callus induction. The best response for primary callus induction (90%) was obtained when MS medium was supplemented with 5 mg/l 2,4-D and 500 mg/l malt extract. Best results for embryogenic callus induction (80%) were obtained in C8 medium. The induction of somatic embryos was highest when MS medium was supplemented with 1 mg/l BAP and maturation of somatic embryos occurred when MS medium was supplemented with 5 mg/l 2,4-D and 1 mg/l BAP. Maximum plantlets were regenerated (92%) from the somatic embryos on half strength MS medium with no hormones. The plantlets were successfully acclimatized in different potting mixtures and highest survival rate (100%) was achieved in potting mixture containing sand and peat moss (2:1).

Taxonomic position and morphology of plant Cydonia is a monotypic genus (containing single species) which belongs to family Rosaceae, subfamily Spiraeoideae, tribe Pyreae, and subtribe Pyrinae. Mostly it grows as shrub or small tree. It comprises pubescent to tomentose buds, petioles, leaves, and fruit. Leaves are ovate to oblong, about 2 inches across and 4 inches long. The solitary white flowers are 1.5-2.0 inches across, having 5 petals, 20 or more stamens, 5 styles, an inferior ovary with many ovules, and are borne on current season of growth (Figure 1).

Roots are biennial, paired and have tubers. They are whitish or grey in colour. Stems are known to be erect, simple and branched. They are 15-20 cm high, glabrous below and finely crispopubescent in the upper part. Leaves are known to be heteromorphous and glabrous possessing long petioles, and blades are orbicularcordate or ovate-cordate in outline with a usually narrow sinus (1-1.5 cm deep). The leaves are usually 5-lobed. A. heterophylum.

It is considered as an important medicinal plant which is mostly used in the traditional medicinal system for asthama, jaundice, fever, malaria, snake bite and liver disorders Different pharmacological activities of P. kurroa include anti-microbial, anti-oxidant, anti-bacterial, antimutagenic, cardio-protective, hepato-protective, anti-malarial, anti-diabetic, anti-inflammatory, anti-cancer, anti-ulcer and nephro-protective activities were recorded from this plant. So far, Iridoids (Picroside I and II), Cucurbitacins and Phenolic components are the different phytochemicals which are extracted from P. kurroa. The authentification of P. kurroa raw material for commercially available herbal/botanical products is essential and it is done by the DNA fingerprinting of P. kurroa. Because of the over-exploitation of P. kurroa for medicinal purposes, the conservational status of P. kurroa in different regions became endangered. It is the need of the hour to utilize different conservational strategies and save this medicinal wealth from extinction as it is widely used by the local people for curing different diseases and thus it cause immense pressure on the plant population.

Among them, Saussurea lappa (S. lappa) is a representative perennial herb, globally distributed across Himalaya region. S. lappa has been traditionally used in medicines without obvious adverse effects. Despite significant progress in phytochemical and biological analyses of S. lappa over the past few years, inclusive and critical reviews of this plant are anachronistic or quite limited in scope. The present review aims to summarize up-to-date information on the active constituents, pharmacology, traditional uses, trade and challenges in conservation and sustainable use of S. lappa from the literature. In addition to botanical studies and records of the traditional use of S. lappa in over 43 diseases, scientific studies investigating the latent medicinal uses of this species and its constituent phytochemicals for a range of disorders are presented and discussed. The structure, bioactivity, and likely mechanisms of action of S. lappa and its phytochemicals are highlighted. Although some progress has been made, further scrupulous efforts are required to investigate the individual compounds isolated from S. lappa to validate and understand its traditional uses and develop clinical applications. The present review offers preliminary information and gives direction for further basic and clinical research into this plant.

Extensive research is going on for commercializing nanoproducts throughout the world. Due to their unique properties, nanoparticles have gained considerable importance compared to bulk counterparts. Among other metal nanoparticles, zinc oxide nanoparticles are very much important due to their utilization in gas sensors, biosensors, cosmetics, drug-delivery systems, and so forth. Zinc oxide nanoparticles (ZnO NPs) also have remarkable optical, physical, and antimicrobial properties and therefore have great potential to enhance agriculture. As far as method of formation is concerned, ZnO NPs can be synthesized by several chemical methods such as precipitation method, vapor transport method, and hydrothermal process. The biogenic synthesis of ZnO NPs by using different plant extracts is also common nowadays. This green synthesis is quite safe and ecofriendly compared to chemical synthesis. This paper elaborates the synthesis,...
