The objective of the study was to formulate and evaluate the antioxidant activity and the wound healing effect of the Punica granatum peel extracts formulation. Tannins, alkaloids, flavonoids, proteins, and phenols were present in the ethanolic extract, which is further formulated in a gel formulation. Seven herbal gel formulations were prepared using 1.5% of the gelling agent’s carbopol 940 (F1-F7). Formulations were evaluated for physical appearance, viscosity, extrudability, pH, and spreadability. The antioxidant study was evaluated in-vitro, using 2, 2-diphenylpicrylhydrazyl (DPPH), and reducing power assays. It was found that all the gel formulation has good power to inhibit DPPH and good reducing power. The antimicrobial properties were evaluated by agar well diffusion method. The result indicated that F5 and F7 exhibited good antimicrobial properties. The highest potential was observed in the F7 against E. coli and B. subtilis. Wound healing was studied using excision wounds on rat models. Treatment of wound with a gel containing 2% and 10% (w/w) ethanolic extract exhibited better-wound healing activity than the positive control....

Realising the immense medicinal values of secondary metabolites in drug formulations, the present study was conducted on an important sec metabolite i.e., ellagic acid (tannin) in in-vivo (leaf) and in-vitro callus tissues of Woodfordia fruticosa a much used medicinally important plant. The present method provided a quick and easy approach for the detection and quantitation of biomarker ellagic acid. Qualitative analysis showed the presence of ellagic acid in both in-vivo and in-vitro (callus) samples of Woodfordia fruticosa. Analytical method high-performance thin-layer chromatography (HPTLC) was developed for the quantification of ellagic acid in in-vivo and in-vitro samples of the various solvent systems tried, the system containing toluene-ethyl acetate-formic acid-methanol (3:3:0.8:0.2 v/v) gave the best resolution of ellagic acid (Rf 0.65) from the other components of the sample extracts, and enabled their simultaneous quantification. Quantitative evaluation of the plate was performed in the remission/absorption mode at 280 nm by the use of a TLC Scanner III CAMAG. The amount of ellagic acid was estimated to be about 0.21% w/w for leaf...

To analyze the efficacy of topical nepafenac, 0.1% eye drops in the treatment of diabetic macular edema (DME). Method: a prospective interventional study in 14 eyes having center involving DME were taken into consideration. They were administered topical nepafenac eye drops 0.1% thrice daily for 6 months. Their vision and foveal thickness were recorded systematically at the start of the treatment and then at 2nd, 4th, and 6th month follow up. Results: The mean baseline and final Log MAR visual acuity were 0.33 and 0.15, respectively and the mean baseline and final foveal thickness were 450 µm and 290 µm respectively. Conclusion: A statistically significant improvement was noticed in the visual acuity and foveal thickness after the administration of 0.1% of topical nepafenac eye...

Plants and fruits have medicinal purposes, and they are being used long before the prehistoric period. Among the different varieties of citrus fruits, Citrus aurantifolia (Kagoji labu) is widespread in tropical and subtropical regions around the World. It is one of the major citrus fruits and widely consumed, but there is limited evidence about its health-promoting properties. In the present study, we evaluated the phytochemical and antioxidant properties of this citrus fruit since phytochemicals through anti-oxidant properties have played a significant role in human health protection and treatment of many diseases. Polyphenol, flavonoid, tannin and reducing sugar contents were found 4.68 ± 0.36 g GAE / 100 g extract, 615.38 ± 17.75 mg CE / 100 g extract, 12.5 ± 6.25 g TAE / 100 g extract and 51.69 ± 7.50 g GE / 100 g extract, respectively. Significant antioxidant activities of C. aurantifolia via 2, 2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging and ferric reducing antioxidant power (FRAP) were detected. Earlier studies have reported that almost all species of citrus...

The objective of this study was the extraction, recuperation, identification and bioactivity evaluation of the main bioactive compounds present in Chrysactinia mexicana A. Gray, polyphenolic compounds from aerial parts of Chrysactinia mexicana A. Gray were purified using a liquid chromatography column with ambulate XAD-16, first elution was made with distilled water, then ethanol was used to recover the phenolic fraction. These compounds were screened for antibacterial activity using agar diffusion method and antioxidant potential method was determined by ABTS•+, DPPH• and FRAP methods. Most bioactive compounds studied were effective against Klebsiella pneumoniae ATCC 13883, Escherichia coli ATCC 8739 and Salmonella enteric ATCC 7251, the compounds presented moderate inhibition against Staphylococcus aureus CDBB 1005. The polyphenolic profile was determined by HPLC/ESI/MS. The content of total hydrolyzable polyphenols (THP) after purification was 18.17 mgg -1, the content of total condensed total condensed polyphenols (TCP) determined after the extract purification was 18.25 mgg -1. The antioxidant activity of polyphenolic compounds of C. Mexicana (CMG) was determined by the IC50 of ABTS•+– scavenging...
