Bioactive compounds are the frontline potent agents in both nutraceuticals and pharmaceutical industries. The bioactive compounds are gaining much importance for their ability in enhancing resistance to various diseases and to improve the health of people both by traditional and modern ways of administrations. R. vomitoria is one of the medicinal plants used traditionally to manage hypertension, diabetes and mental disorder. This present study sought to characterize the bioactive components of R. vomitoria leaf and root ethanol extracts using Gas-Chromatography-Mass Spectrophotometry (GC-MS). The results of the GC-MS analysis provide different peaks indicating the presence of 22 phytochemicals in the plant leaf and 16 phytochemicals in the root. The major bioactive compounds in the leaf were squalene (18.69%), phytol (16.47%), n-hexadecanoic acid (15.68%), 7-tetradecenal, (Z) (12.90%), 9,12,15-octadecatrienoic acid, ethyl ester, (Z,Z)-, (9.56%) and others, while the roots contains; cis-vaccenic acid (32.13%), n-hexadecanoic acid (15.41%), (E)-9-octadecenoic acid ethyl ester (9.83), cyclohexanecarbonitrile 1-(-4- chlorophenyl (9.45%), 8H-azeceno[5,4-b] indol-8-one, 5-ethylidene (7.66%) and other minor compounds. Pharmacological activities of these compounds indicated that the compounds present in the leaf of the plant can be used as a crude drug which could be developed into a novel drug. Some of these compounds have antimicrobial, antioxidant, hepatoprotective, hypocholesterolemic as well as cancer preventive activities amongst others. The findings suggest that there is an indication that both R. vomitoria leaves and roots contain potent bioactive compounds that may be linked to its beneficial effects on health, with the leaf taking the lead. It is therefore recommended as a plant of phytopharmaceutical significance.

Sphenocentrum jollyanum is a plant genus of the family Menispermaceae. It has high medicinal importance as it is used traditionally to treat various diseases such as jaundice, breast engorgement related to the menstrual cycle, tumour, fibroids and improve the health of people. The present investigation was carried out to analyze the bioactive compounds present in ethanol crude extract of Sphenocentrum jollyanum leaves using GC-MS analysis. GC-MS analysis of ethanol extract Sphenocentrum jollyanum was done using a 7890A GC system (Agilent Technologies), coupled with 5977B MSD (Agilent Technologies) while the mass spectra of the compounds found in the extract was matched with the National Institute of Standards and Technology (NIST) library. A total of 45 bioactive compounds representing 99.98% of the total extract based on the retention time, peak area, molecular formula, molecular weight, and biological activities were identified by GC-MS which ranges from high molecular weight to low molecular weight compounds. The major compounds identified with their peak area percentages were 2,4-Di-tertbutylphenol, (21.05%), Z-8-Methyl-9-tetradecenoic acid (19.12), Hexadecanoic acid, ethyl ester (7.86%), Diisooctyl phthalate (7.13%), Phytol, Oleic Acid (7.03), 6,9,12- Octadecatrien-1-ol (6.65%), 3-Eicosene, (E)-(4.63%), 2-Methyl-Z, Z-3,13-octadecadienol (4.24%), n- Hexadecanoic acid (4.09%), trans-13-Octadecenoic acid (3.81%), Cyclohexene, 4-(4-ethylcyclohexyl) -1- pentyl- (3.74%), Dibutyl phthalate (3.20%), and 9-Oxabicyclo (6.1.0) nonane, cis-(3.18%). The presence of these major phytoconstituents in the leaf extract provides various biological activities including antifungal, antibacterial, antioxidant, anti-inflammatory, and anti-tumour which supports the ethno-medicinal uses of the plant in curing diseases.

Background: Polyherbal plant extracts which usually comprise of two or more plant parts often contain a wide array of key phytoactive constituents relevant in attaining greater therapeutic efficacy. The active constituents derived from individual plants are insufficient to provide attractive pharmacological action when compared to a combination of multiple herbs. Objective: To conduct phytochemical screening of polyherbal aqueous leaf extracts                            (PALE) and analysis of compounds present in it by gas chromatography-mass spectrometry (GC-MS). Materials and Methods: The polyherbal extract was prepared from the combined aqueous extracts of leaves of Alchornea cordifolia, Sorghum bicolor and Pennisetum glaucum using ratio 1:1:1 w/v. Phytochemical screening was done via standard analytical methods. The identification and characterization of compounds by GC-MS analysis was performed on gas chromatography system coupled with mass spectrometry. Results: The phytochemical analysis of PALE revealed the presence of phenols, saponins, flavonoids, alkaloids and tannins in varying quantities. GC-MS analysis of the extract depicts the presence of key bioactive compounds. Thirty-two bioactive compounds were identified with various retention time and % peaks. The major compounds identified in terms of % peak area are n-Hexadecanoic acid (6.72), Hexadecanoic acid, ethyl ester (7.28), 9,12-Octadecadienoic acid (16.54) and 9-Octadecenoic acid ethyl ester (12.92). Disulfide, dimethyl (0.04), 2-Methoxy-4-vinylphenol (0.28), 1-Dodecanol (0.85), 10-Phenyldecanoic acid (0.12), 1-Hexadecanol (0.75), Methoxyacetic acid, pentadecyl ester (0.27), 9-Octadecenoic acid (Z)-, phenylmethyl ester (0.16), Hexadecanoic acid, 2-hydroxy-1-(hydroxymethyl) (1.09), were among the minor compounds identified in the extract. From the study, 9,12-Octadecadienoic acid indicated the highest peak with a retention time of 20.556 minutes and % peak area of 16.54%. Conclusion: The presence of the revealed bioactive constituents in PALE may suggest its nutraceutical, pharmacological and therapeutic relevance. Therefore, in view of the medicinal importance associated with the observed bioactive constituents, further studies on the toxicity level of  the extract is advised subsequently.

Abstract Background This study focused on the evaluation of the bioactive compounds of Vernonia amygdalina Del. leaf extracts and their antibacterial potential on some water-related bacterial isolates. The bacterial isolates were confirmed using standard microbiological test. The leaves of V. amygdalina were subjected to extraction using the Maceration method with water and ethanol as the extraction solvents. Gas chromatography–mass spectroscopy (GC–MS) was carried out on extracts. Antibacterial susceptibility test of V. amygdalina extracts on isolates was carried out. Results Aqueous extract of V. amygdalina had a higher percentage yield (11.89%) than the ethanol extract (5.37%). The GC–MS carried out revealed the presence of butanoic acid, squalene, palmitaldehyde, octadecanoic acid, Z-hexadecanoic acid ethyl ester, oxirane, tetradecyl, 3- methyl-2-phenylindole, n-heneicosane, phytol, methyl-2-O-benzyl-d-arabinofuranoside, cholest-5-en-3-ol acetate; with hexadecanoic acid ethyl ester and 1,1-diethoxy-3methylbutane having the highest percentage composition of 24.37% and 13.42% in aqueous and ethanol extract, respectively, aqueous extract highly inhibited Escherichia coli with an inhibition zone of 10.333 ± 0.882 and 36.667 ± 0.882 for 25 mg/ml and 100 mg/ml, respectively, while the ethanol extracts inhibited most of the isolates with an inhibition range of 7.000 ± 1.155 to 30.333 ± 0.882. The minimum inhibitory concentration for both extracts on the isolates varies from 25 to 50 mg/ml. Conclusions The ethanol extract of V. amygdalina had a higher inhibitory activity on the bacterial isolates than water. These findings indicate the potential of ethanol extract of V. amygdalina leaf in the treatment of water borne infections.

Manilkara subsericea(Mart.) Dubard (Sapotaceae) is popularly known in Brazil as “guracica.” Studies withManilkaraspp indicated the presence of triterpenes, saponins, and flavonoids. Several activities have been attributed toManilkaraspp such as antimicrobial, antiparasitic and antitumoral, which indicates the great biological potential of this genus. In all, 87.19% of the hexanic extract from fruits relative composition were evaluated, in which 72.81% were beta- and alpha-amyrin esters, suggesting that they may be chemical markers forM. subsericea. Hexadecanoic acid, hexadecanoic acid ethyl ester, (E)-9-octadecenoic acid ethyl ester, and octadecanoic acid ethyl ester were also identified. Ethanolic crude extracts from leaves, stems, and hexanic extract from fruits exhibited antimicrobial activity againstStaphylococcus aureusATCC25923. These extracts had highIC50values against Vero cells, demonstrating weak cytotoxicity. This is the first time, to our knowledge, that beta- and alpha-amyrin caproates and caprylates are described forManilkara subsericea.
