Carissa macrocarpa is commonly known as Natal plum. Its fruits are palatable and used in manufacture of jams while other parts of the plant are used in traditional medicine to treat various diseases. The main objective of current study was to screen the presence of and isolate the various phytochemicals applying standard procedures and to evaluate the in vitro antidiabetic activity using α-amylase inhibitory assay. The total methanol extract of flower (TMEF) of Carissa macrocarpa was subjected to several chromatographic procedures. Results demonstrated that TMEF of Carissa macrocarpa is characterized by the content of different constituents such as flavonoids, steroids, saponins, tannins and carbohydrates at different levels. Chromatographic isolation led to the isolation of kaempferol-3-O-robinobioside and caffeic acid, which were confirmed via using 1H, 13C, DEPT, COSY, HMQC and HMBC NMR spectroscopic analyses. TMEF exhibited α-amylase inhibitory activity with IC50 value of 65.4 μg/ml when compared to that of the acarbose (standard) (IC50 = 39.6 μg/ml). In conclusion, current investigation endorses the traditional use of Carissa macrocarpa as antidiabetic herb. Hence, the studied TMEF of Carissa macrocarpa may have the potential being nutraceuticals products for pharmaceutical applications as antidiabetic herbal remedy.

Truffles are natural food product very famous for its health benefits for being significant biosource of essential fatty acids, proteins and other antioxidant and phenolic compounds. The current study was conducted to evaluate the phytochemicals, antioxidant and lipoxygenase inhibition activities of Terfezia boudieri of Saudi origin. Various phytochemicals were screened applying standard procedures. The total methanol extract (TME) of the truffle was subjected to several chromatographic procedures. The antioxidant activity was evaluated by DPPH antioxidant procedure, comparing results with trolox as standard. Results demonstrated that Terfezia boudieri chemically characterized by the availability of various constituents such as flavonoids, steroids, saponins, tannins and carbohydrates at different levels. Phytochemical investigation led to the isolation of β-sitosterol and gallic acid that were identified using 1H, 13C, DEPT, COSY, HMQC and HMBC NMR spectroscopic data. Results demonstrated high antioxidant activity with IC50: 50.4 μg/ml and 31.4 μg/ml for TME and gallic acid, respectively. TME and gallic acid exhibited lipoxygenase inhibitory activity with IC50 values 4.59 and 0.53 μg/ml for TME and gallic acid, respectively. The higher lipoxygenase inhibitory activity was presumably correlated to the high antioxidant activity. In conclusion, current investigation confirms the folklore use of Terfezia boudieri as antinflammatory food. Hence, the studied Terfezia boudieri may have a great potential as antioxidant and antinflammatory functional food and nutraceuticals products for pharmaceutical applications.

Natural coumarins are reputed to demonstrate several biological effects to improve adverse health conditions including; obesity. This study was conducted to explore the potential in vitro lipid and glucose modulatory activity of cichorioside on 3T3-L1 cell lines . Methods: The 3T3-L1 cell lines were cultured and cell viability was assessed. Glucose content in medium of cultured cells was measured. Differentiation of 3T3-L1 cells from pre-adipocytes to adipocytes was evaluated upon addition of cichorioside. Expression of mRNA of the peroxisome proliferator-activated receptor gamma (PPARγ) was estimated. Results: Survival of around 90\% of cultured cells was observed at 10μM cichorioside. Cichorioside inhibited glucose uptake from the medium by the 3T3-L1 cell lines. Cichorioside considerably inhibited pre-adipocyte differentiation and the lipid content in intercellular storage. Cichorioside demonstrated an upregulation of the mRNA expression of PPARγ. Moreover, the docking studies supported the results via the deep interaction of cichorioside with amino acids residue of PPAR-γ. Taken together, these findings are the first report on in vitro evaluation of cichorioside to modulate the lipid storage and glucose uptake of cultured 3T3-L1 cell lines

The main objective of current approach was to screen the presence of different kind of metabolites applying standard procedures followed by assessment of total phenolic (TPC) and flavonoids (TFC) contents. In addition, the in vitro ABTS antioxidant and lipoxygenase activities were evaluated. Different organs (leaves, stems and flowers) of Anisosciadium lanatum were extracted using 70\% methanol to yield total methanol extracts of leaves (TML), stems (TMS) and flowers (TMF). Results demonstrated that TML, TMS and TMF are characterized by the content of different constituents such as flavonoids, phenolics/tannins, steroids, saponins, and carbohydrates at different levels. Ethyl acetate (EA) and butanol (BT) fractions of TML and TMS demonstrated the highest percentage of TPC and TFC. The results demonstrated the competence of EA and BT as free radical scavenger fractions compared to other fractions and its opportunity to contain bioactive antioxidant metabolites . TML, TMS and TMF exhibited Lipoxygenase inhibitory activity with IC50 values of 4.88, 5.40 and 6.05 μg/mL, respectively when compared to that of the positive control baicalein (IC50: 0.27 μg /mL). In conclusion, present investigation highlighted the potential of Anisosciadium lanatum to be promising candidate with activity against wide range of inflammatory-related diseases.

Background: The effectiveness of antibiotics used in the treatment of bacterial infections has been on the decline due to bacterial resistance. To improve clinical management of recalcitrant bacterial infections, alternative therapy such as medicinal plant products are now being evaluated. This study investigates the antimicrobial effects of Garcinia kola fractions on clinical isolates of multidrug resistant gram negative bacteria and Candida. Materials and Methods: Escherichia coli\ , Acinetobacter baumannii, Serratia marcescens and Candida species were used for the study. Microbial isolation and antimicrobial susceptibility test was carried out using basic microbiological procedures. Confirmation of all isolates was done using the VITEK 2 compact automated system (BioMerieux, Marcy I\’Etoile France). The powdered dried seeds of G. kola were extracted with 70\% methanol for 7 days, using a cold maceration method. The crude extracts were evaporated to dryness, using different solvents to obtain the fractions according to standard fractionation techniques. Results: The aqueous, butanol, chloroform and hexane fractions at minimum inhibitory concentrations (MIC) of 25mg/ml were active against A. baumannii. Ethyl acetate fraction at MIC of 20 mg/ml also produced growth inhibition of same isolates. At the same MICs, the different fractions were observed to inhibit the growth of candida albicans (CF1) isolate. Overall, aqueous fraction of G. kola produced more growth inhibition followed by butanol fractions, with chloroform fractions producing the least effects. Conclusion: The antibacterial potencies of these extracts could be useful for the treatment of multi-drug-resistant A. baumannii. The aqueous fraction showed better activities than the other fractions studied.
