Ward Taifi (Taif rose) is considered one of the most important economic products of Taif, Saudi Arabia. In this study both fresh and dry Taif rose were biologically and phytochemically investigated. The 80% methanol extracts andn-butanol fractions of dry and fresh Taif rose had high radical scavenging activity toward artificial 1,1-diphenyl picrylhydrazyl (DPPH)•radical with SC50values range 5.86−12.24 µg/ml whereas the aqueous fractions showed weak activity. All samples hadin vitroanticancer activity toward HepG2 with IC50< 20 µg/ml which fall within the criteria of the American Cancer Institute. High positive correlation appeared between the antioxidant activity and total phenolics whereas there is no correlation between total phenolics and anticancer activity. The LC-ESI(− ve)-MS analysis of all extracts indicate the presence of phenolic compounds belonging to hydrolysable tannins and flavonol glycosides. In conclusion, the presence of this is considered to be the first phytochemical report that identifies the major compounds in dry and fresh roses using HPLC-ESI-MS. The methanol extracts and itsn-butanol and aqueous fractions for both fresh and dry Taif rose could be used as preventive and therapeutic effective natural agents for diseases in which free radicals involved after morein vitroandin vivostudies.

In vitro efficacy of five indigenous plants namely Bishkatali (Polygonum hydropiper), Neem (Azadirachta indica), Papaya (Carica papaya), Korolla (Momordica charantia) and Mahogany (Swietenia macrophylla) were studied against the development of Ascaridia galli eggs from July 2007 to May 2008. Fresh juice, extracts and dust of leaves were tested. Fresh juice of leaves were trialed at 5%, 10% and 20% concentrations; aqueous, ethanol and methanol extracts were used at 1%, 2% and 4% concentrations and dusts of leaves were applied at 10% and 20% concentration. Among the trials, 4% of methanol extracts of papaya showed the highest efficacy (92.86%) followed by 4% ethanol extract of papaya (92%). Among the selected plants and in all three concentrations of fresh juice of leave, Bishkatali (88.46% at 20% conc.) was the highest effective plant against the development of A. galli eggs. Papaya showed the highest efficacy (71.42%) in 1% aqueous solution, but bishkatali was found as the best (73.33% and 83.33% respectively) in 2% and 4% concentration of ethanol extract of the five selected plants. In vitro screening of 5 plants with ethanol extract revealed that papaya was the highest efficacious plant (92% at 4% conc.) against development of A. galli eggs. Among the plants, in all concentrations of methanol extract of leaves, papaya was observed as best plant (92.86%, 88% and 78.95% at 4%, 2% and 1% of conc. respectively) followed by bishkatali (80% and 75% at 4% and 2% of conc. respectively) and neem (78.57% and 73.08% at 4% and 2% conc. respectively). In two concentrations of dust of leaves, bishkatali was observed as the effective plant (75% at 20% and 73.33% at 10% conc.) among the five plants. The present study suggests that dust of bishkatali leaves can be used with litter for inhibition of development of A. galli eggs and fresh juice and extract of bishkatali, neem and papaya may be impregnated in litter and used after sun dry.

Gmelina arborea Roxb has important economic value in Nigeria and worldwide. It has been used as timber, for pulp and paper, furniture, plywood and for particle board. Due to the menace caused by fungal diseases in nurseries and sites where the seedlings are raised and the observed disease severity at the Awi Gmelina Forestry Project Nursery in Cross River State, Nigeria. It became necessary to provide a viable environmentally friendly measure to curb the diseases, hence, a trial on the antifungal effects of leaf extracts of Carica papaya and Azadirachta indica in-vitro using different extract solvents on some pathogenic fungi isolated from Gmelina arborea seedlings. The isolated fungi were Trichoderma viride (from stem and leaf) and Mucor mucedo (stem and leaf). The solvents used were ethanol, methanol, propanol, butanol, acetone, chloroform and distilled water. Phytochemical screening of extracts of C. papaya from the different solvents showed that there was no tannin and hydroxymethyl anthraquinine. Flavonoids and polyphenols were in excess in acetone and methanol extracts respectively. For A. indica, polyphenols were only found in excess in ethanol and methanol extracts. Application of the extracts at different percentages of 0% (control), 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% and 100% showed that Carica papaya extracted with butanol was more potent on Trichoderma viride and Mucor mucedo at 60%, 70%, 80% and 100% while the growth of Trichoderma viride and Mucor mucedo was checked by butanol extracts of A. indica at 70%, 80%, 90% and 100%. Conclusively, butanol extracts of C. papaya and A. indica at higher concentrations is recommended for use as spray to control the diseases.

Plant-derived digestive enzyme inhibitors particularly those targeted to carbohydrate metabolism has been the focus of recent studies as natural supplements for weight control and diabetes. The present study explores the salivary amylase inhibition activity of Garcinia mangostana (Linn.) pericarp extracts and Carica papaya (Linn.) leaf extracts and fractions, as well as perform phytochemical screening and quantification, and thin layer – and high performance liquid chromatographic profiling. ­Results show that crude extracts and purified fractions were able to inhibit salivary amylase, with C. papaya fraction 1 being the most active at 30.89% inhibition. Phytochemical screening of all extracts tested ­positive for tannins, glycosides, phenolics, flavonoids and alkaloids. Quantification of phenolics showed that extracts contained high levels of phenolics, with C. papaya crude extract having the highest content with 219.0±12.7 mg GAE/g extract followed by G. mangostana crude extract with 247.1±18.0 mg GAE/g extract. Quantification of total flavonoids also showed C. papaya crude extract to contain the highest content with 55.12±0.679 mg QE/g extract. All extracts contained negligible alkaloid content, though. HPLC and TLC profiling showed several peaks and bands, when viewed in 210 nm and UV light, respectively. These results demonstrate in vitro the salivary amylase inhibitory activity of both plants and their potential as antidiabetic drug candidates; however, further studies need to be done, like isolation and structure elucidation of active components and toxicity assays. Keywords: Amylase inhibition, phytochemical quantification, Carica papaya, Garcinia mangostana

The role of vitamin D is implicated in carcinogenesis through numerous biological processes like induction of apoptosis, modulation of immune system inhibition of inflammation and cell proliferation and promotion of cell differentiation. Its use as additional adjuvant drug with cancer treatment may be novel combination for improved outcome of different cancers. Numerous preclinical, epidemiological and clinical studies support the role of vitamin D as an anticancer agent. Anticancer properties of vitamin D have been studied widely (both in vivo and in vitro) among various cancers and found to have promising results. There are considerable data that indicate synergistic potential of calcitriol and antitumor agents. Possible mechanisms for modulatory anticancer activity of vitamin D include its antiproliferative, prodifferentiating, and anti-angiogenic and apoptic properties. Calcitriol reduces invasiveness and metastatic potential of many cancer cells by inhibiting angiogenesis and regulating expression of the key molecules involved in invasion and metastasis. Anticancer activity of vitamin D is synergistic or additive with the antineoplastic actions of several drugs including cytotoxic chemotherapy agents like paclitaxel, docetaxel, platinum base compounds and mitoxantrone. Benefits of addition of vitamin D should be weighed against the risk of its toxicity.
