Background: Increasing prevalence of microbial resistance and side effects of currently available drugs compels the researchers to look for alternate therapies and formulations to overcome this problem. Plant based formulations have been proved to be most reliable agents in recent times. Objective: In the current study, bio fabricated herbal silver nanoparticles (HSNPs) were prepared by reducing silver nitrate (AgNO3) solution with ethyl acetate fractions (EAF) of Blumea lacera extracts. These bios conjugated HSNPs were then assessed for potential anti-inflammatory and antibacterial activities along with in vitro antioxidant effect. Methods and Results: The synthesis was confirmed by absorbance peak at 441 nm due to surface plasmon resonance in UV-visible spectrophotometer. FTIR spectra of HSNPs indicated the phytochemicals having C-O bond responsible for reducing of Ag+ to Ago. Average size of HSNPs was found to be 59.21 nm which was in good agreement with TEM and SEM results. EDS analysis showed the existence of Silver, Nitrogen and Carbon in HSNPs. The antibacterial activity of HSNPs in terms of zone of inhibition (ZOI) via disc diffusion assay and against Staphylococcus aureus and Escherichia coli was found to be 25.0{\textpm}1.19 mm and 18.3{\textpm}2.08 mm, respectively. The minimum inhibitory concentration (MIC) of HSNPs was found to be 50 μg/ml and 60 μg/ml against S. aureus and E. coli, respectively. The antioxidant capacity of the HSNPs was insignificant as compared to EAF but the results of anti-inflammatory activity was significant (p\<0.05). Conclusion: The overall result demonstrated better in-vitro pharmacological potential of HSNPs compared to neat extract/EAF.

Objective: To investigate pharmacognostical and physico-chemical standardization of Euphorbia neriifolia leaves. Materials and Methods: Fresh and dried leaves with powder samples of E. neriifolia were examined macroscopically and microscopically. As per Ayurvedic Pharmacopeia of India and World Health Organization guidelines on quality control methods for medicinal plants materials suggested parameters were determined for standardization of E. neriifolia leaves. Physico-chemical, primary phytochemical, fluorescence and quantitative screenings along with primary HPTLC fingerprinting assessment were performed. Results: Macroscopic examination demonstrated that fresh leaf of E. neriifolia has dark green in colour, herbaceous odour with characteristic taste. Dried leafs are grey brownish in colour, characteristic odour with broken crumpled and papery fracture. Microscopy of leaf showed the single layered thick rectangular or tubular adaxial epidermal cells. Mesophyll tissue was differentiated into two or three layered adaxial zones of radially elongated palisade cells and wider abaxial spongy mesophyll cells revealed the differentiated dorsiventral lamina. Mid-rib composed of epidermis, collenchymas and spongy parenchyma cells. Physico-chemical parameters like, foreign matter was found to be 0.46\%. Total ash, acid insoluble ash and water soluble ash was found 6.33\%, 1.23\% and 6\% respectively. Loss on drying was found to be 4.69\%. Swelling and foaming index was found 11.7 ml and 333 ml respectively. Quantitative screening suggested that the leaf powder has indicated alkaloid and saponin estimation as 0.26\% and 3.67\% respectively. The HPTLC fingerprinting of EN6 extract fraction was showed the Rf values at 254 nm with their respective UV-visible spectrum wavelengths scanned in between 200-400 nm. They are 0.01 (265 nm), 0.05 (369 nm), 0.09 (263 nm, 264 nm), 0.18 (400 nm), 0.20 (279 nm), 0.31 (400 nm), 0.44 (378 nm), 0.45 (382 nm), 0.54 (377 nm), 0.55 (383 nm), 0.62 (400 nm), etc. at different concentrations of sample application. The HPTLC plate was also scanned at 366 nm and 540 nm. Conclusion: The present investigation is an additional standardization research in support with previous reports and will be helpful for qualitative and quantitative standardization of herbal formulations containing E. neriifolia. Further investigations are going on this extract fraction in reference to identification, quantification and validation of HPTLC methods using various standard marker compounds along with exploration of its pharmacological activities.

Background: Quality, safety and efficacy of medicines used form the back\­bone of every health care system. Shelf-life is the length of time, after which all substances start to degrade in their qualities and become unsuit\­able for consumption or sale. The saviryatavadhi of churna is considered to be 2 months according to ayurvedic classics. The use of modern pack\­aging technology and preservatives have increased the shelf life period of ayurvedic medicines and the shelf life period of churna is 2 years according to Rule 161-B, Drugs and Cosmetics Act. To ascertain the quality, hridya yoga churna was taken up to assess its shelf life period. Methods: Accelerated stability study (includes evaluation of organoleptic and physic-chemical parameters, assay of active constituents and microbial load) and Comparative HPTLC (High Performance Thin Layer Chromatography) were done to evaluate the shelf life of the Hridya yoga churna. Atomic absorp\­tion spectrophotometry was done to analyze the heavy metal content in the sample. Results and Conclusion: In the present study the shelf life period of Hridya yoga churna is found to be 3 years and 7 months. Similar Rf values obtained in HPTLC analysis of hridya yoga churna initially and after six months showed the minimum deterioration of the product. The presence of heavy metals namely arsenic, cadmium and lead were not detected and mercury was present within permissible limits.
