Phyto-Fingerprinting of Putranjiva roxburghii Wall. Leaf Extract and its In Vitro Anti-Inflammatory Activity

Abstract

Putranjiva roxburghii is an important medicinal plant utilized for remedy of female reproductive ailments. Its seed extract is being used as a uterine health booster due to the presence of several pharmaceutically important phytochemicals. However, the presence of phytochemicals in its leaf is still unexplored. The present study was designed to explore phytochemical finger printing and assessment of anti-oxidant and anti-inflammatory activities of hydroalcoholic leaf extract of P. roxburghii (HALEPR). The qualitative, quantitative phytochemical of flavonoid, phenol and HRA-MS analysis of HALEPR carried out along with antioxidant and in vitro membrane stabilization and protein denaturation assay of anti-inflammatory activity were have been analyzed. Results of qualitative phytochemical screening of HALEPR denotes the existence of phenol, flavonoids, alkaloids, coumarins, steroids, saponins, tannins, anthroquinone and carbohydrates. The quantitative phytochemical of flavonoid and phenol was done which revealed the presents of total phenol and flavonoid. High resolution accurate-mass spectrometry (HRA-MS) study was also done for the identification of bioactive compounds from the HALEPR, which showed the presence of various phytochemicals such as luteolin 3′- (3″-acetylglucuronide), luteolin 4′-methyl ether 7-glucoside, quercetin-3β-D-glucoside, 8-hydroxyluteolin 4′-methyl ether 8-glucuronide, quercetin 3-xylosyl- (1- > 2) -rha mnosyl- (1- > 6) –glucoside, quercetin-3β-D-glucoside, myricetin 3- (3-6-diacetylglucosyl) - (1- > 4) - (2″,3″-diacetylrhamnoside), apigetrin, isorhamnetin, catechin 7,3′-Di-O-β-D glucopyranoside, luteolin 7-methylglucuronide, apigenin-8-C-α -l-arabinopyranoside, naringenin 7- O-β-D-glucoside 6″-acetate,ohobanin, shogaol, ginkgetin and amoritin. The HELPER is shown to have the presence of anti-oxidant and anti-inflammatory activities as demonstrated by DPPH (1, 1-diphenyl,2-picrylhydrazyl) and membrane lysis assays. Our findings reveal the presence of phytochemicals in HALEPR that have significant antioxidant and anti-inflammatory activity. The bioactivities were identified using chemical characterization like HRA/MS and biological assessments like anti-inflammatory and antioxidant assays. Future research may focus on isolating specific molecules, conducting in vivo tests, and creating HALEPR-based formulations for clinical application as anti-inflammatory drugs.
