Antimicrobial efficacy of phyto-synthesized silver nanoparticles using aqueous leaves extract of Rosamarinus officinalis L.

The current research investigation demonstrated that the aqueous leaves extract of Rosamarinus officinalis possesses cardinal phyto-chemicals to fabricate AgNPs in an eco-friendly way. The phyto-synthesized AgNPs were characterized to be stable, monodispersed, polycrystalline and mostly spheroidal in conformation. The nano-spheriods were observed to be 25-75 nm in diameter, displaying λmax peak at 430 nm. From the comparative antimicrobial investigations, it was observed that AgNPs manifested tremendous bactericidal properties against all test organisms particularly S. epidermis (89%), S. aureus (84%) and K. pneumonia (84%), owing least MIC values of 40µL. The aced fungicidal activity was also exhibited by AgNPs against all fungal test species particularly C. herbarum (90%), A. flavus (85%), R. stolonifer (85%) and C. jadinii (85%). In contrast to AgNPs, all crude ethanolic, aqueous, methanolic and n-hexanoic extracts manifested less to moderate antimicrobial activity against all test micro-organisms with three-fold escalating MIC values i.e., 160µL.

Investigating the therapeutic potential of aqueous extraction of curry plant (Murraya koenigi) leaves supplementation for the regulation of blood glucose level in type 2 diabetes mellitus in female human subjects.

Type 2 diabetes mellitus is characterized by hyperglycemia and insulin resistance. It is spreading around the globe like a pandemic. Major factors behind the development of diabetes can be genetics, environmental factors, dietary choices and obesity. Many medicinal plants have anti-diabetic potential. This study has investigated the anti-diabetic effect of curry leaves extract. This study also investigated the chemical characterization of curry leaves. Phytochemicals including saponins, tannins, alkaloids, flavonoids, phenols and glycosides were also investigated. Encapsulated 5mg per kg of the body weight and 10mg per kg of the body weight were given to treatment groups I and II. Random blood sugar, fasting blood sugar and HbA1c of 45 diabetic female adults were measured on the 0-day and 45th days. All results were analyzed using the two-sample t-test in IBM SPSS Statistics 20. Curry leaves contained moisture (24.1±1.78)%, ash (17.82±2.13)%, nitrogen free extract (36.12±3.52)%, crude protein (8.32±0.83)%, crude fiber (6.98±2.31)% and crude fat (6.87±0.21)%. Mineral analysis showed that magnesium and calcium were major minerals present in curry leaves. Curry leaves extract contained saponins 2.71±0.23, flavonoids 7.84±0.42, tannins 0.91±0.09, glycosides 0.17±0.01, phenols 3.89±0.12, alkaloids 2.01±0.87. These phytochemicals were expressed in mg/100 g of the sample. Curry leaf extract showed a significant (p<0.05) reduction in fasting blood sugar, random blood sugar and glycated hemoglobin in both treatment groups.

Investigating the nutraceutical potential of apple peel extract supplementation for regulating the glucose metabolism in hyperlipidemic Female human subjects.

Hyperglycemia is a condition often observed in diabetics, dyslipidemia and obese. It is a major factor behind the development of diabetes and the reasons can be genetics, environmental factors, dietary choices and obesity. Many medicinal plants have anti-diabetic potential. This study investigated the anti-hyperglycemic effect of apple peel extract. This study also investigated the chemical characterization of apple peel. Phytochemicals including total phenolics and flavonoids were determined. Encapsulated 350mg/day was given to treatment groups. Random blood sugar, fasting blood sugar and HbA1c of 45 diabetic female adults was measured on the 0-day and 45th day. Results showed that apple peel contained moisture (14.71±3.57)%, ash (17.82±2.13)%, nitrogen free extract (32.12±3.52)%, crude protein (6.89±0.83)%, crude fiber (19.17±0.21)% and crude fat (9.91±2.31)%. Findings showed that apple peel contains magnesium (6.61±1.088), calcium (8.17±0.32), zinc (14.08±1.21) and potassium (67.21±1.86). These findings were shown in mg in kg. Apple peel extract contained total phenolic content (TPC) of 8.14±1.07 and total phenolic content (TFC) of 4.89±1.81. Apple peel extract showed a significant reduction in all blood parameters of hyperglycemia. All results were significant at p<0.05.

Antimicrobial activity of AgNO3 nanoparticles synthesized using Valeriana wallichii against ESKAPE pathogens.

The emergence of multidrug-resistant ESKAPE infections has emerged as a serious public health threat. Nosocomial infections are most often caused by ESKAPE bacteria. To combat multidrug-resistant ESKAPE, the research team used Valeriana Wallichii extracts and nanoparticles. The well diffusion technique was used to test antimicrobial activity on Muller Hinton agar medium. The FTIR, SEM and XRD techniques were used to characterize the nanoparticles synthesized in an environmentally benign manner. Both NPs performed better than extracts made with methanol and water in this investigation. The smallest zones of inhibition were shown against A. baumannii and Enterobacter cloacae, whereas the largest zones of inhibition were seen against E. faecium. However, NPs synthesized from shoot extracts exhibited remarkable effects against all MDR ESKAPE infections, with zones of inhibition of 23, 20, 12, 18, 22 and 14mm, respectively. Although E. faecium. had the largest inhibitory zone in both methanolic root and shoot extracts (19mm and 22mm, respectively), K. pneumonia and E. cloacae had the smallest zones when tested with these solvents. Water-based extracts inactivated multidrug-resistant bacteria. Our research show that extracts and nanoparticles have stronger antibacterial efficiency because biologically active substances including Terpenoids, Alkaloids, Phenol and Pholobutannins affect people and microbe.

Determination of chemical composition and investigation of potential of triphala powder in hypercholesterolemia in men in controlled randomized trial.

Hypercholesterolemia is a condition with elevated cholesterol and lipid profile. It is the leading reason behind myocardial infarction and coronary heart disease. It is observed in young people as well due to a sedentary lifestyle. Triphala powder has a hypolipidemic and anti-hypercholesterolemia effect. This study was designed to investigate the effect of triphala powder against hypercholesterolemia. This study also examined Triphala powder's chemical composition. Total phenolic and flavonoid content were examined. Encapsulated 400 mg and 600 mg Triphala powder were given to treatment groups I and II. Lipid profile parameters were measured and compared at 0 weeks and 10th weeks in all groups. All results were analyzed using ANOVA in IBM SPSS Statistics 20. Results of proximate analyses have shown that Okra pod powder contains moisture 12.27%, ash 11.25%, nitrogen-free extract 45.93%, crude protein 13.37%, crude fat 2.95% and crude fiber 14.23%. Mineral analysis showed that iron and manganese are major minerals in triphala powder. Triphala powder showed a significant reduction in lipid profile parameters in hypercholesterolemia. All results are taken significantly at p<0.05.
