Adenanthera pavonina belongs to the leguminous non-climbing plant, with a very prominent value in food chain and therapeutic medicine of traditional origin. The purpose this study was evaluate GC-MS analyzed methanolic leaf extract for proximate analysis, phytochemical screening mineral content determination order authenticate its nutraceutical propensity. leaves were collected, washed distilled water, dried under shed powdered. revealed presence alkaloids, saponin, flavonoids,...

This work identifies the chemical components of Azadirachta indica (neem plant) leave extracts. A. is a vascular plant which belongs to Meliaceae family and its use as herb in folk medicine widely acclaimed. Essential oils were extracted from leaves indica. Steam solvent extraction methods used with two solvents: Ethanol Hexane. The crude oil using both analyzed GC–MS. result analyses show that major constituents Eicosane (9.7662%), Diacenaphtho[1,2-j:1′,2′-l]fluoranthene (11.301%), Phenol,...

Adenanthera pavonina is leguminous species which a perennial and non-climbing tree highly valuable plant for food, drink, traditional medicine.The Linn Seed was obtained in our institution premises.This present study targeted at evaluating proximate analysis, phytochemical determination, physicochemical parameter of the spectroscopically characterized oil sample pavonina.The extracted by standard method had percentage yield 15.36%.The screening revealed presence saponin, alkaloid,...

Background: This study was carried out to investigate proximate composition, phytochemical profile and antimicrobial activity of the spectroscopically characterized seed oil Bauhinia tomentosa.Materials method: The characterization using FT-IR, mass spectra, 1 H-and 13 C-NMR.Results: results from analysis showed presence crude protein 30.36±0.98%,crude fibre 26.00±0.69%,carbohydrate 25.32±0.57%,moisture content 12.04±0.39%,ash 4.00±0.15%and fat 2.28±0.09%.The screening revealed alkaloids,...

Abstract Medicinal plant research is a highly diversified topic of interest owing to applications their phytoconstituents in drug discovery, human dietary intake, corrosion inhibition, material science among others. The study revealed the phytochemical composition and proximate determination Pentaclethra macrophylla benth (African oil bean) seed. dried seeds were pulverized into fine powder portion it was extracted with n-hexane. result screening extract from showed that contained...

This paper investigates biochemical constituents of Solanum aethiopicum leaf, for its prospect on the total-corrosion reduction concrete steel-rebar in chloride-contaminated environment. Atomic absorption spectroscopy (AAS) and Fourier transform infra-red (FTIR) were used assessment inorganic organic leaf. Steel-rebar was analysed, as per ASTM G109-99a, from macrocell-current measurements 3.5% NaCl-immersed steel-reinforced samples that admixed with different concentrations leaf-extract. By...

Abstract The degradation of mild steel has been an issue concern in most industries. Because this challenge, (AISI 1015 carbon steel) was inhibited using ethanolic extract from leaves and peels Chrysophyllum albidum ( C. ) 1 M H 2 SO 4 investigated gravimetric (weight loss), gasometric potentiodynamic polarization (PP) methods. Samples were placed acidic medium tested at different concentrations extract. PP experiment indicated that the inhibition efficiency (I.E) ranges 70.9‐85.9 %...
