The present study reveals the facile biosynthesis of silver nanoparticles from the root extract of Abutilon indicum, a medicinal plant which acts as a reducing agent. The surface plasmon resonance (SPR) of silver nanoparticles was characterized using UV-Vis spectrophotometer and observed at 421 nm. The nanoparticles were found as spherical uniform and monodispersed and the particle size ranges from 15-20 nm from the scanning electron microscopy. The presence of elemental silver in the synthesized nanoparticles was observed by using EDX (Energy dispersive X-ray spectrophotometer) and the XRD (X-ray diffraction) data predicts the crystalline nature of the nanoparticle. The interface of nanoparticles with the root extract of Abutilon indicum was carried out by FT-IR (Fourier Transform Infrared spectroscopy). In the end, the activity of crude extract and synthesized silver nanoparticles were tested against the common human pathogens like E. coli, S. aureus, S. typhi, P. aeruginosa, K. planticola and B. subtilis. A choice of concentrations of the nanoparticle in colloidal form was used to analyze the antibacterial activity from 20 µL. The nanoparticle synthesized by using root extract of Abutilon indicum, exhibits strong bactericidal activity, which was identified by the clear zone of inhibition and it has huge application in the field of medicine.

An anticancer activity of methanolic root extract of Withania somnifera collected from four different regions of India were screened in vitro by SRB method on four Human cell lines viz.U373-MG, MCF- 7, HCF-15, OVKAR-3. Plants growing under different agroclimatic condition often show qualitative and quantitative variations in their phytoconstituents. The methanolic roots crude extract were compared with two known steroidal lactones i.e. Withaferin-A and Withanolide-A which are known to be therapeutically active. For the screening of anticancer activity, LC50, TGI, GI50 were considered. The results obtained reveal that standard Withaferin-A had high potency towards the entire studied cell lines tested whereas Withanolide -A, did not show anticancer activity against any cell line. Among the studied samples viz. WsK, WsN, WsM and WsL, only WsK showed potency towards breast cancer cell line (MCF-7) at a concentration of 16.8 µg/ml.

The present study evaluates the in vitro antioxidant free radical scavenging capacities of aqueous and alcoholic extracts of a herbal rejuvenator drug prepared by adding equal amounts of dried roots of Sida cordifolia and Glycyrrhiza glabra because these two medicinal plants have been used since ancient times in the Ayurvedic system of medicine and elaborated in its ancient texts such as Charak Samhita (Chikitsa Sthanam). Phytochemical analysis indicated the presence of flavonoids, tannins, carbohydrates and saponins. The total phenolic content of the alcoholic extract and the aqueous extract was found as 26.50 and 28.60 Gallic acid equivalents/mg while the total flavonoid content was assessed as 85.91 and 80.31 Quercetin equivalents/mg respectively. IC50 (µg/ml) of alcoholic, aqueous extract and Ascorbic acid was found to be 57.027±5.200, 44.507±1.252 and 17.48±1.356 in Hydrogen Peroxide Radical Scavenging, 0.823±0.033, 0.745±0.075 and 0.722±0.090 in DPPH radical scavenging and 232±15.163, 179±53.894 and 6.627±0.061 during FRAP essay. Similarly, during ABTS radical scavenging, IC50 (µg/ml) was assessed as 332.960±2.177, 162.155±9.736 and 6.779±0.167 for alcoholic, aqueous extract and Trolox respectively. While both the extracts showed substantial and significant free radical scavenging activity during the study which is compared to that of the standard drug, the aqueous extract of the herbal rejuvenator research drug exhibits higher in vitro antioxidant activity than the alcoholic extract possibly due to higher concentrations of phenolic compound in it, validating and confirming therapeutic properties ascribed to it in Ayurvedic texts.

L-Arginine is a semi essential amino acid. Even if it is normally synthesized in the body, supplementations are required in certain conditions. It is required for various functions in the body. Hence it is essential to evaluate its concentration in the formulation by suitable method.Two types of Tablet formulations viz. Female Aphrodisiac (FSF)-1 and Male Aphrodisiac (MSF)-1 were prepared, using 600mg L-Arginine hydrochloride each and other ingredients. Both the formulations were subjected to quality evaluation. Presence of all ingredients was confirmed by HPTLC, however, quantification of Arginine, was carried out by applying simple and easiest “Non aqueous titration method”. Quantification of L-Arginine hydrochloride and L-Arginine was carried out in API i.e. in authenticated raw materials, in granules as well as in corresponding tablet formulations viz. FSF-1 and MSF-1.L-Arginine hydrochloride was found to be more than 99% in both raw materials (API). In granules of FSF-1 and MSF-1 analytical findings were 59.747% and 56.378% respectively. In corresponding tablet formulations, observed values were more than 100% of theoretical expected value.Non aqueous titration method was found to be suitable for quantification of L-Arginine hydrochloride and can be used for controlling the quality of the tablet formulation.
