Ramie (Boehmeria nivea) is one of the Urticaceae family plants with various potential for pharmacological development. In this study, we analyzed the bioactive content of the n-hexane extract of B. nivea leaves and flowers, and the crude extract was tested for antibacterial activity. The metabolites in the leaves and flowers of ramie were analyzed using a Gas Chromatography-Mass Spectrometer (GC-MS). Antibacterial potential analysis was carried out by disc diffusion method using n-hexane extract of ramie leaves and flowers at concentrations of 20%, 40%, 60%, 80%, and 100% in inhibiting Escherichia coli and Klebsiella pneumoniae. Antibacterial potential was observed based on the average result of three observations of the diameter of the clear zone to determine the effectiveness of the extract. The results showed that the metabolome data of the n-hexane extract of ramie leaves were obtained as many as 40 compounds. Meanwhile, ramie flower metabolome analysis obtained 47 compounds, but one compound has not been identified. The crude n-hexane extract of B. nivea flower gave antibacterial activity at 80% and 100% concentrations against E. coli with an average clear zone of 9.15 ± 0.31 mm and 10.29 ± 0.28 mm. In contrast, the n-hexane extract of B .nivea leaves did not show any antibacterial activity. The results of confirmation of the dominant compound by GC-MS showed that the n-hexane extract consisted of tetratetracontane, tetracontane, Stigmast-5-en-3-ol,(3.beta.,24S)-(CAS)Clionasterol, methyl commate D, and 2,6,10,14,18,22-Tetracosahexsaene,2,6,10,15,19,23-hexamethyl-, (all-E). The n-hexane extract of B. nivea is recommended for other potential biological activities, such as anti-inflammatory, antioxidant, and analgesic.

This study was designed to apply the highly sophisticated biological and chemical characterization techniques–(GC-MS) Gas chromatography-mass spectrometry and FTIR spectroscopy to screen for bioactive phytocompounds present in ethanol and methanol extracts of U. lobata .The leaves of the plant were collected from a farm in Umuode village in Osisioma Ngwa local government area of Abia state, Nigeria. Ethanol and methanol extracts of the leaves were prepared and analyzed using Buck M910 Gas chromatography system with HP-5MS column (30m in length x250µm in diameter x 0.25µm in thickness film). Analysis of functional groups in the phytocompounds were done using Buck scientific M530 USA FTIR.12 vibrational functional groups were revealed by the FTIR screening in the ethanol and methanol extracts of U. lobata leaves. Some of the functional groups were indicative of alcohols, phenols, aromatic compounds, unsaturated hydrocarbons, vinyl ethers, amines, isonitriles and aliphatic compounds. GC-MS analysis of the ethanol leaf extract revealed 41 bioactive compounds with the following being most abundant, 9-octadecenoic acid(16.8%), dodecenoic acid(13.43%),n-hexadecanoic acid(11.73%), octadecanoic acid (9.78%), 1-docosene(9.57%) while the methanol extract revealed 47 bioactive compounds with the following having the highest abundance, n-hexadecanoic acid (26.65%) and (9.11%), dodecanoic acid(6.89%), 1-docosene(6.06%), erucic acid(4.09%).These phytocompounds and many others present in the leaf have been reported to possess multiple therapeutic activities. This therefore explains the use of this leaf in ancient medicine to treat numerous disease conditions. It further implies that the leaf could be exploited for the formulation of therapeutic molecules.

Bacterial endophytes are well-acknowledged inoculants to promote plant growth and enhance their resistance toward various pathogens and environmental stresses. In the present study, 71 endophytic strains associated with the medicinal plant Thymus roseus were screened for their plant growth promotion (PGP), and the applicability of potent strains as bioinoculant has been evaluated. Regarding PGP traits, the percentage of strains were positive for the siderophore production (84%), auxin synthesis (69%), diazotrophs (76%), phosphate solubilization (79%), and production of lytic enzymes (i.e., cellulase (64%), lipase (62%), protease (61%), chitinase (34%), and displayed antagonistic activity against Verticillium dahliae (74%) in vitro. The inoculation of strain XIEG05 and XIEG12 enhanced plant tolerance to salt stress significantly (p < 0.05) through the promotion of shoot, root development, and reduced the activities of antioxidant enzymes (SOD, POD, and CAT), compared with uninoculated controls in vivo. Furthermore, inoculation of strain XIEG57 was capable of reducing cotton disease incidence (DI) symptoms caused by V. dahliae at all tested salt concentrations. The GC-MS analysis showed that many compounds are known to have antimicrobial and antifungal activity. Our findings provide valuable information for applying strains XIEG05 and XIEG12 as bioinoculant fertilizers and biological control agent of cotton under saline soil conditions.
