From the stem bark hexanic extract of Garcinia chapelieri, chapexanthone A, B were isolated using combinations of column and thin-layer chromatographic methods. Their structures were elucidated by NMR spectroscopic methods, mainly 1D and 2D NMR.

BACKGROUND Extracts from Potentilla species have been applied in traditional medicine and exhibit antioxidant, hypoglycemic, anti-inflammatory, antitumor and anti-ulcerogenic properties, but little has been known about the diversity of phytochemistry and pharmacology on this genus. This study investigated and compared the phytochemical profiles, antioxidant and antimicrobial activities of leaf ...

The radio protective effectiveness of methanol extract of Garcinia indica against whole body gamma radiation was premeditated in Swiss albino mice. The oral administration of Garcinia indica extract at 800 mg / kg body weight / day for 15 consecutive days before whole body exposure to radiation was found to be effective with the LD50/30 values of 7.21 and 8.83 Gy for irradiation alone and Garci...

The ability to perform movement imagery has been shown to influence motor performance and learning in sports and rehabilitation. Self-report questionnaires have been developed to assess movement imagery ability in adults, such as the Movement Imagery Questionnaire 3 (MIQ-3); however, there is a dearth of developmentally appropriate measures for use with children. To address this gap, the focus ...

The new species Pharaxonotha esperanzae (Coleoptera: Cucujoidea: Erotylidae: Pharaxonothinae) is described. It feeds on the pollen of the endangered Cuban cycad Microcycas calocoma (Miq.) A. DC. and breeds in its male cones. Its potential role as a pollinator of Microcycas is discussed. Resumen: Se describe la especie nueva: Pharaxonotha esperanzae (Coleoptera: Cucujoidea: Erotylidae: Pharaxono...

We present a practical and systematic strategy for measuring machine intelligence quotient (MIQ) of human–machine cooperative systems. So far, much research related to intelligent control has been established, but the issues about definition and measurement of machine intelligence are not yet clearly formulated. We propose the Intelligence Task Graph (ITG) as a modeling and analysis tool. By us...

A new species, Garcinia hopii H.Toyama & V.S.Dang is described from Bidoup Nui Ba National Park, southern Vietnam. This species is similar to Garcinia hendersoniana Whitmore but differs from that species in having larger leaves, clustered pistillate flowers, a greater number of sterile anthers and a larger stigma of young fruits. A description, preliminary conservation assessment, illustration,...

Bioassay-guided fractionation of a Satureja parvifolia MeOH extract led to the isolation of eriodictyol, luteolin and ursolic and oleanolic acids as its active components against Plasmodium falciparum K1. This is the first time these compounds are reported as constituents of S. parvifolia. Ursolic acid showed an IC50 of 4.9 microg/ml, luteolin 6.4 microg/ml, oleanolic acid 9.3 microg/ml and eri...

Garcinia is a plant under the family of Clusiaceae that is commonly used as a flavouring agent. Various phytochemicals including flavonoids and organic acid have been identified in this plant. Among all types of organic acids, hydroxycitric acid or more specifically (-)-hydroxycitric acid has been identified as a potential supplement for weight management and as antiobesity agent. Various in vi...
