Tetrapleura Tetraptera

The use of antioxidants has emerged as a promising therapeutic strategy for the management of mitochondrial dysfunction and other oxidative stress-related degenerative pathologies. Tetrapleura tetraptera is a well-known tree and its fruit is applied traditionally as spice and in the preparation of remedies for different ailments. In this study, the gas chromatography-mass spectrometry (GC-MS) analysis and mitochondrial functionality potential of T. tetraptera fruits were investigated. GC-MS was used to detect compounds in then-hexane and ethanol extracts of T. tetraptera fruits. Cupric reducing antioxidant capacity (CUPRAC) assay was used to evaluate the mitochondrial functionality potential of the ethanol extract. GC-MS analysis revealed the presence of six compounds in then-hexane extract of T. tetraptera fruits. These compounds were detected in trace quantities, the most abundant being 2,3-dimethyl-3-buten-2-ol (0.04%). The compounds: cis-vaccenic acid (35.37%), n-hexadecanoic acid (28.09%), 6-octadecenoic acid (25.21%), and octadecanoic acid (11.33%) were identified in the ethanol extract of the fruits. Consequently, the ethanol extract was subjected to CUPRAC assay. The ethanol extract exhibited a concentration-dependent high cupric reducing capacity, returning CUPRAC values in the range of 0.090 to 0.403 at the concentration of 10 – 80 μg/ml. This activity was comparable to that of the positive control, naringenin, which showed CUPRAC values of 0.059 – 0.378 at the same concentrations. These results indicate that T. tetraptera fruits possess good antioxidant property as evaluated by other related antioxidant assays. This could be attributed to a synergistic effect of the phytochemical constituents. Hence consumption of T. tetraptera fruits could be beneficial for the prevention of mitochondrial dysfunction and other oxidative stress-related degenerative disorders.

ABSTRACT Sclerotium rolfsii is a soil-borne fungal plant pathogen that causes diseases in more than 500 plant species. Chemical fungicides used to control this disease cause environmental pollution, therefore, plant derived compounds can be used as alternative to synthetic fungicides to reduce environmental pollution. Chenopodium album is a weed of family Chenopodiaceae that is used as food and also has medicinal importance. In the present study, antifungal activity of methanolic root extract of C. album was evaluated against S. rolfsii using six concentrations viz. 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 g 100 mL-1 amended in malt extract as growth medium. All the root extract concentrations significantly reduced fungal biomass by 15-58% over control. Gas chromatography-mass spectrometry (GC-MS) analysis of the methanolic root extract of C. album was performed. Six compounds were identified in methanolic root extract through GC-MS analysis. The most abundant compound was 1,2-benzenedicarboxylic acid, mono(2-ethylhexyl) ester (58.56%) followed by 9-octadecenoic acid (Z)-, methyl ester (12.75%) and 9-octadecenoic acid (Z)-, methyl ester (10.27%), which might be responsible for antifungal activity of methanolic root extract of C. album.

Gas Chromatography-Mass Spectrometry (GC-MS) is normally used for direct analysis of chemical components existing in herbal medicines. The medicinal plants are having numerous bioactive components which are identified even at less than 1ng by using GC-MS or LC-MS analysis. The aim of this study is to identify the secondary metabolites present in the leaves of B. tomentosa using gas chromatography-mass spectrometry (GC-MS) analysis. In the present study the ethanol extract of the leaves of Bauhinia tomentosa has been subjected to GC-MS analysis, while the mass spectra of the compounds found in the extract was matched with the National Institute of Standards and Technology (NIST) library. GC-MS analysis revealed the presence of 14 secondary metabolites. These compounds were identified by comparing their retention times and peak areas with those from the literature and by interpretation of the mass spectra. The major secondary metabolites were DL-.alpha.-tocopherol (14.84%), 2-[(trimethylsilyl oxy]-, methyl ester, 1-alpha,2-alpha.-epoxy-1-beta-methylcholesta-4,6-dien-3-one (12.93%), pentacosenoic acid (12.71%), phytol (10.28%), Ethyl Isoallocholate (8.197%), Spirost-8-en-11-one-3-hydroxy-,(3-beta,5 alpha,14 beta,20 beta, 22 beta,25R)-(8.162%), Urs-12-en-28-ol (6.675%), 1-Octadecyne (5.702%) and Cholest-8-en-3-beta-ol,Acetate (5.426%). The compounds having area less that 5% were considered of no significance. These findings suggest that the presence of these secondary metabolites may be the cause for the properties exhibited by Bauhinia tomentosa. Thus, presence of various bioactive compounds justifies the use of the leaf for various ailments by traditional practitioners.

Oxidative stress plays a relevant role in the progression of chronic conditions, including cardiometabolic diseases. Several Cameroonian plants, including spices, are traditionally used as herbal medicines for the treatment of diseases where oxidative stress contributes to insulin resistance, like type 2 diabetes mellitus. This study evaluated the antioxidant capacity and the effects on oxidative-stress-induced impairment of glucose uptake of 11 Cameroonian spice extracts. H2O2-induced reactive oxygen species (ROS) production by human HepG2 cells was significantly reduced by 8/11 extracts. The most effective extracts, Xylopia parviflora, Echinops giganteus, and Dichrostachys glomerata, showed a concentration-dependent ROS-scavenging activity, which involved Nrf2 translocation into the nucleus. Xylopia parviflora, Tetrapleura tetraptera, Dichrostachys glomerata, Aframomum melegueta, and Aframomum citratum extracts showed the highest antioxidant capacity, according to oxygen radical absorbance capacity (ORAC) (2.52–88 μM Trolox Eq/g of extract), ferric-reducing antioxidant power (FRAP) (40.23–233.84 mg gallic acid Eq/g of extract), and total phenol (8.96–32.96% mg gallic acid Eq/g of extract) assays. In HepG2 cells, glucose uptake was stimulated by 4/11 extracts, similarly to insulin and metformin. H2O2-induced oxidative stress reduced glucose uptake, which was rescued by pretreatment with Xylopia aethiopica, Xylopia parviflora, Scorodophloeus zenkeri, Monodora myristica, and Dichrostachys glomerata extracts. The ROS-scavenging ability of the spice extracts may reside in some secondary metabolites observed by phytochemical profiling (reverse-phase high-performance liquid chromatography coupled to a diode array detector (HPLC-UV-DAD)). Further studies are needed to better clarify their biological activities and potential use to control oxidative stress and promote insulin sensitivity.
