It is important to monitor the quality of the phytopharmaceutical product as its therapeutic potential depends on standardized delivery of active ingredients present in the botanical source. Minimal presence of toxic impurities like heavy metals (HMs) is warranted to ensure product safety and prevent hazardous health impacts. In the present study, conducted as part of the development of a novel phytopharmaceutical product, the chemical profile of 13 heavy metals (Fe, Cu, Mn, Zn, Ni, Co, Mo, V, Cr, As, Pb, Hg, and Cd) was studied in the whole plant, fruit, and rhizome of Bacopa monnieri, Hippophae rhamnoides, and Dioscorea bulbifera, respectively, from environmentally diverse regions in India. Most samples had HM profiles within permissible limits as established by regulatory authorities, with the exception of Cd and Hg in low-altitude regions. This study indicates geographical regions in India suitable for procuring raw materials to develop and manufacture phytopharmaceutical products.

The present work discusses the establishment of a green route for the rapid synthesis of silver nanoparticles (AgNPs) using an alcoholic extract of Reinwardtia indica (AERI) leaves which act as a reducing as well as a capping agent. The change in color from yellowish green to dark brown confirmed the synthesis of AgNPs. A characteristic surface plasmon resonance (SPR) band at 436 nm advocated the presence of AgNPs. The synthesis process was optimized using one factor at a time approach where 1.0 mM AgNO concentration, 5 mL 0.4% (v/v) of AER inoculum dose and 30 min of sunlight exposure were found to be the optimum conditions. The synthesized AgNPs was characterized by several characterizing techniques such as HR- TEM, SAED, HR-SEM, EDX, XRD, FTIR and AFM analysis. For evaluation and comparison of AgNPs with AERI used human pathogen E. coli, P. aeurogenosa, S. aeurus and C. albicans for antimicrobial, for cytotoxicity study SiHa cell line at concentration of (10, 50, 100, 250 and 500 µg mL) and for enzymatic assay superoxide dismutase, catalase, malondialdehyde and glutathione peroxidase method were used. The size of nanoparticle in the range of 3-15 nm was confirmed TEM, spherical shape by SEM and crystal lattice nature by XRD. AFM results revealed the 2 D and 3 D pattern of particle scatter nature on the surface. This protocol as simple, rapid, one step, eco-friendly, nontoxic and AgNPs showed strong antimicrobial activity as well as cytotoxic potential in comparison to AERI.

The present study aimed to evaluate the safety of the alcoholic leaves extract of Reinwardtia indica in Charles foster rats through an acute and sub-acute oral administration.For assessment of acute oral toxicity test, ratswere orally treated with single dose of the alcoholic leaves extract of Reinwardtia indica at the doses of 50, 250, 500, 1000 2000 and 5000 mg/kg. In sub-acute toxicity study, using the OECD guidelines no. 407, the extract was administered at the doses of 50, 250, 500, 1000, 2000 mg/kg/day for 28 consecutive days and at the dose of 2000 mg/kg satellite group also used for 6 weeks.In acute toxicity above mentioned doses neither showed mortality nor exterior signs of toxicity. In sub-acute, study no significant changes found in haematological and biochemical level ofthe treated rat after 14 days and 28 days in comparison to control. The histopathology of rat brain, kidney, liver, and heart also showed the no cellular changes after extract treated rat.The alcoholic leaves extract of Reinwardtia indica was found non-toxic in single drug dose administration up to 5000 mg/kg (acute study) and in sub-acute administration up to 2000 mg/kg.
