ABSTRACT A new lupane-type triterpene, 3alpha-hydroxy-lup-20(29)-en-24-oic acid, was isolated from the methanolic extract of "Erytrean-type" resin of commercial frankincense together with the known 3alpha-hydroxy-olean-12-en-24-oic acid (alpha-boswellic acid) and 3alpha-hydroxy-urs-12-en-24-oic acid (beta-boswellic acid). Their structures were characterized on the basis of chemical and spectral evidence including two dimensional NMR experiments and mass spectrometric techniques.

    ABSTRACT: In this research the properties of three types of Gum grown in Sudan i.e. Gumminesina olibanum, Guar Cyamopsis teyragonlobus and Combretum Combertaceae were investigated. The tested physicochemical parameters were: moisture and ash contents, nitrogen, protein, pH, equivalent weight, uronic acid, tannin content, specific rotation and viscosity. The analysis results showed: 5.35, 6.70 and 9.10 % moisture content, 1.77, 0.63 and 4.33 % ash , 0.27, 0.71 and 0.96 % nitrogen, 1.68, 4.18 and 6.45 % protein, - 40.31, + 75.87 and -38.10 specific rotation, 3.85, 5.62 and 5.25 pH values, 1.335, 1.336 and 1.338 refractive indeces, 0.150, 0.233 and 0.079 % tannin, 3.23, 0.46 and 2.49 viscosity for olibanum, guar and combretum respectively. The main sugars present were 6.10, 2.05 and 8.23 % arabinose and 6.93, 39.22 and 48.79 % galactose for olibanum, guar and combretum respectively. Low percent of manose, rhamnoe and D-glucuronic acid were reported. The elemental content of sodium, calcium, potassium, magnesium, copper and phosphorus was determined. The water holding capacity was found to be: 65.15, 60.35 and 65.40 for olibanum, guar and combretum respectively. While the emulsifying stability was found to be: 1.046, 0.037 and 1.006 for olibanum, guar and combretum respectively. The FTIR spectra supported the existence of sugar moiety in the composition of gum. The findings indicated that combertum has good gum properties close to those of gum Arabic.

    ABSTRACT: 11-keto-β-boswellic acid (KBA) is an important and potent boswellic acids responsible for anti-inflammatory action of boswellia extract. However, its pharmaceutical development has been severely limited by its poor oral bioavailability. The present work aims to investigate the permeability related hurdles in oral delivery of KBA. Gastrointestinal stability, gastrointestinal metabolism, adsorption-desorption kinetics and Caco-2 permeability studies have been carried out. KBA was found poorly permeable with Papp value of 2.85±0.14×10(-6)cm/s. Higher absorptive transport indicated role of carrier mediated transport. Moreover, KBA transport across monolayer showed saturation kinetics at higher concentrations. KBA exposed to 1α, 25-(OH)2 vitamin D3 treated cell monolayer showed the lowest Papp value of 2.01×10(-6)±0.02×10(-6)cm/s indicating role of CYP3A4 mediated metabolism during KBA transport. Metabolic stability experiments in jejunum S9 fractions further confirmed this. KBA was found unstable in simulated gastrointestinal fluids and also got accumulated in the enterocytes. Sorption and desorption kinetic studies using Caco-2 cells further confirmed accumulation of KBA inside the enterocytes. KBA also showed pH dependent permeability with higher flux at gradient pH condition of pH 6.5 at apical and 7.4 at basolateral. Taken as whole, the major permeability related hurdles that hampered oral bioavailability of KBA included its gastrointestinal instability, CYP3A4 mediated intestinal metabolism, accumulation within the enterocytes and saturable kinetics. The present investigation may help in designing novel drug delivery system for KBA.
