Disease relevance of Clusiaceae

• The crude ethanol extract from the leaves of Tovomitopsis psychotriifolia (Clusiaceae) exhibits antibacterial activity against Bacillus cereus, Staphylococcus aureus, and Pseudomonas aeruginosa [1].

High impact information on Clusiaceae

• YCT is a semipurified extract from Cratoxylum cochinchinense that has antioxidant properties and contains mostly mangiferin [2].
• A new natural xanthone, 1,3-dihydroxy-6,7-dimethoxy-2,8-diprenylxanthone, together with four known compounds, fuscaxanthone C, 1,7-dihydroxyxanthone, 3-geranyloxy-6-methyl-1,8-dihydroxyanthraquinone and 2-geranylemodin were isolated from the stem bark of Cratoxylum arborescens (Vahl) Blume [3].
• A phytochemical investigation of the 80% ethanolic extract of stem bark of Vismia orientalis Engl. (Guttiferae or Clusiaceae), a plant used in traditional medicine in Tanzania, resulted in the isolation and spectroscopic characterisation of 3-geranyloxy-6-methyl-1,8-dihydroxyanthraquinone, emodin, vismione D and bianthrone A1 [4].
• Three compounds, namely the interesting biflavanonol GB-2(naringenin 1-3, 11-8-dihydroquercetin, 1), 1-4',1-5,11-5,1-7,11-7-pentahydroxyflavanone(l-3,11-8)chromone [naringenin-(3 -8) 5,7-dihydroxychromone, 21 and stigmasterol, have been isolated from the leaves of Cratoxylum neriifolium Kurz [5].
• The protein kinase C (PKC) modulatory effects of euxanthone, isolated from the wood of Cratoxylum maingayi, on isoforms alpha, betaI, delta, eta and zeta were characterised using an alternative in vivo yeast phenotypic assay [6].

Biological context of Clusiaceae

• (Hypericaceae) crude ethanol extract (A), ethyl acetate extract (B), aqueous extract (C) and infusion (I), on pentobarbital induced sleeping time, intestinal motility, and their analgesic activity, have been investigated [7].

Associations of Clusiaceae with chemical compounds

• Supercritical fluid extraction of tea catechins including epigallocatechin-3-O-gallate (EGCG) and epicatechin-3-O-gallate (ECG) from Cratoxylum prunifolium Dyer was performed [8].
• A new prenylated xanthone, named allanxanthone A, was isolated from the stem bark of Allanblackia floribunda in addition to known compounds, 1,5-dihydoxyxanthone, 1,5,6-trihydroxy-3,7-dimethoxyxanthone, stigmasterol and stigmasteryl-3-O-beta-D-glucopyranoside [9].
• A new prenylated xanthone, 5-O-methylcelebixanthone (1), together with six known compounds; celebixanthone (2), 1,3,7-trihydroxy-2,4-di(3-methylbut-2-enyl)xanthone (3), cochinchinone A (4), alpha-mangostin (5), beta-mangostin (6) and cochinchinone C (7) were isolated from roots of Cratoxylum cochinchinense [10].
• Guttiferone F, the first prenylated benzophenone from Allanblackia stuhlmannii [11].
• In addition to five known compounds including three xanthones, tovophyllin A, rubraxanthone and garciniafuran, one pentacyclic triterpene, lupeol and one phytosterol, stigmasterol, a polyisoprenylated xanthone named allanxanthone B was isolated from the stem bark of Allanblackia monticola [12].

Gene context of Clusiaceae

• Calophyllum brasiliense (Clusiaceae) is a big tree from the Tropical Rain Forests of the American continent [13].
• 6-Geranyloxy-3-methyl-1,8-dihydroxyanthrone, a novel antileukemic agent from Psorospermum febrifugum Sprach var. ferrugineum (Hook. fil) [14].

Analytical, diagnostic and therapeutic context of Clusiaceae

• 7-Epiclusianone, isolated from Rheedia gardneriana, was tested in several biological assays [15].
