Isolation, Characterization and Antioxidant Activity of Plumbago indica L. Extract

Abstract

The studies aimed to evaluate the preliminary parameter and Antioxidant potential of Plumbago indica. Standardization using various analytical techniques was also performed. P. indica was collected and studied for preliminary analysis and antioxidant activity and analyzed using the standard protocol using different analytical techniques. DPPH free radical scavenging activity was used to assess the antioxidant potential. The microscopy indicated the presence of periderm, cork and cortex, sclereids, cork, secondary xylem and medullary rays bordered pitted vessel, calcium oxalate crystal, starch grain, and cork with resin cell. The total ash, moisture, water-soluble, acid soluble ash, water soluble extractive and the alcohol soluble extractive value was 1.388, 5.146, 0.674, 0.19, 3.88, 3.6%, respectively. The presence of variety of phytoconstituents was discovered during phytochemical analysis. The total phenol content (TPC) and total flavonoid content (TFC) of the ethanolic and hydroalcoholic extract was 533.83 and 46.667 mg/gm, respectively and 132.66 and 219.00 mg/gm, respectively. The thin-layer chromatography (TLC), fluorescence in suspension hybridisation (FLASH), ultraviolet (UV), fourier transform infrared spectroscopy (FTIR) and high-performance thin-layer chromatography (HPTLC), analysis illustrated the presence of Plumbagin and antioxidant activities because of its bioactive compounds. The ethanolic extract gives higher antioxidant potential by DDPH free radical scavenging activity. The findings of this study may be useful in establishing botanical and analytical grades for the root of P. indica.

“…Leishman-stained blood smears were used to produce differential counts of WBC. [27][28][29] Biochemical Parameters Blood was allowed to clot & serum was collected (2500 rpm; 15 minutes) for serum glutamate pyruvic transaminase (SGPT), alkaline phosphatase (ALP), total proteins, serum glutamic oxaloacetate transaminase (SWAS), and bilirubin content by standard protocols analysis.…”

“…Currently, tacrine hydrochloride (HCL) (Cognex), rivastigmine (Exelon), donepezil HCL (Aricept), galantamine (Razadyne), and several other medications are being utilised. 12 They enhance the efficiency of nerve cells that are adversely influenced by Alzheimer's disease. Despite this, the results are temporary and do not address the underlying issue.…”
