Objective: The present study was performed to identify the phytochemical constituents of leaves and flowers of a plant Spermadictyon suaveolens extracted with four different solvents.Methods: Dried and powdered samples were subjected to soxhlation based on the polarity of the solvents. The extracts were scanned using Ultra Violet-visible (UV-Vis) spectrophotometry with the wavelength ranging from 200–800 nm by comparing the absorption spectrum with the spectra of known compounds, Fourier Transform Infrared (FT-IR) spectrometry was used to find out the functional groups of the compounds and GC-MS system consisting of a Perkin Elmer Technologies Model Clarus 680 GC equipped with Clarus 600 (EI) was used to identify the metabolites by matching their recorded mass spectra with the standard mass spectra from National Institute of Standards and Technology (NIST05. LIB) libraries provided by the software of the GCMS system (TurboMass version 5.4.2).Results: The phytochemical tests indicated the presence of carbohydrates, alkaloids, flavonoids, phenols, tannins, saponins and terpenoids from the chloroform extract of leaves and flowers. UV-visible spectrophotometer results indicated a wavelength range between 230–660 nm for the flower and leaf extracts for major peaks. FT-IR analysis indicated major functional groups such as aromatic, primary, secondary and aliphatic amines, alkanes, carboxylic acids and amides. GC-MS analysis results revealed major bioactive compounds in the crude extracts.Conclusion: Presence of secondary metabolites has been identified from the phytochemical studies. Many phyto-compounds have been identified from the leaves and flowers of using GC-MS analysis. Hence, this medicinal plant may be used as a source for treating many diseases.

In this study, the antimicrobial compounds present in leaves of Alphonsea madraspatana was identified by using RP-HPLC, LC/MS and GC/MS and found to be active against multiple drug resistant (MDR) bacteria e.g. Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa. Extraction of dried plant leaves was performed by solvent gradient technique. Antimicrobial study was performed with each extract. n-Hexane and methanol extracts were further subjected to analysis for identification of potent antimicrobial compounds due to their better antimicrobial activity as compared to remaining extracts. The methanolic extract was more active than n-hexane extract. As n-hexane extract contains non-polar compounds, it was subjected to GC-MS analysis and methanol extract was subjected to RPHPLC followed by LC/MS due to presence of polar components. Among the isolated compounds, four compounds were identified as potent antimicrobial. RP-HPLC and LC/MS analysis of methanol extract also ensured the presence of four potent antimicrobial compounds as follows: (i) kaempferol-3-O-rotinoside-orhamnoside (m/z 748), (ii) 3-hydroxypropylglucosinolate (m/z 377), (iii) luteolin-7-O-glucoside (m/z 448) and (iv) genistein-7-O-glycoside (m/z 432). Leaves of this plant may be used as potent antibacterial agents due to presence of antimicrobial compounds.

In an attempt to find alternative control methods for stored products insects, extracts of seven plant species (Cassia senna, Caesalpinia gilliesii, Thespesia populnea var. acutiloba, Chrysanthemum frutescens, Euonymus japonicus, Bauhinia purpurea, andCassia fistula) were evaluated under laboratory conditions for their ability to protect wheat (Triticumspp.) grains againstTrogoderma granariuminsect. Moreover, gas chromatography-mass spectrometry (GC-MS) analysis was carried to identify the chemical components of the most effective plant extract againstT. granarium. Furthermore, the safety of the most effective plant extract was evaluated with respect to biochemical and histological changes in treated rats relative to control. The results revealed that, the tested botanical extracts showed high efficiency againstT. granariumwith respect to mortality and progeny of the adults.C. sennawas the most effective botanical extract againstT. granarium. The GC-MS analysis of the most effective plant extract showed the presence of different bioactive compounds that is known by its insecticidal activity. The most effective plant extract showed no toxicity on treated rats relative to control with respect to biochemical and histological changes. The results suggest the ability of using these plant extracts for wheat grains protection as a safe alternative to insecticides.
