GLYCYRRHIZA GLABRA MEDIATED SILVER NANOPARTICLES: SYNTHESIS, CHARACTERIZATION, STANDARDIZATION, AND CARDIOPROTECTIVE BIO EVALUATION Authors: Salunkhe RB* And Patil SS
ABSTRACT
SARS-CoV-2 exacerbated the risk of cardiovascular diseases (CVDs), threatening world health.
Novel drug delivery systems (NDDS) incorporating herbal medicines have the potential to boost
CVD therapy's efficacy. The key intent of this study was to utilize aqueous root extract of
Glycyrrhiza glabra Linn as a green reducing and capping agent for the silver nanoparticles
(AgNPs) fabrication, followed by their characterization, standardization, and assessment for
cardioprotective activity. Stable AgNPs formation was achieved by mixing the aqueous root
extract with 1mM silver nitrate (AgNO3) solution. SEM, TEM, and DLS showed spherical GGNPs
with an average size of 20–50nm. The 430nm surface plasmon band was characteristic. EDAX
(41.69% weight) and ICP-AES (324ug/ml) verified silver content. The synthesized AgNPs were
standardized by validated HPLC method for the content of glycyrrhizic acid as the marker
compound was found to be 2.44±0.105mg. In-vitro release study suggested GGNPs follows the
diffusion and degradation mixed release pattern for the sustain and controlled release. Synthesized
AgNPs were tested for cardio-protection utilizing the CAM assay. GGNPs concentration raised
the number of branching arteries in chicken choriallontoic membrane by 33 ± 2 at 1mg/ml, while100mg/ml GG extract concentration increased it by 38 ± 2. This shows GGNPs are more pro-
angiogenic. In H9C2 cell line toxicity studies, GGNPs had no toxicity after 24 hours. The
aforementioned experimental data on metal nanomedicine derived from herbal sources offers
valuable insights into the scientific foundation for the development of novel treatment therapies in
cardiovascular diseases (CVDs).
