Development of a topical gel containing dried extract of Ipomoea pes-caprae brasiliensis (L.) R. Br. (Convolvulaceae)

Gel formulations containing I. pes-caprae spray dried extract (SDE) at 0.11 and 0.18%, were developed with three types of polymers Ce = Cellosize® QP 100, Ca = Carbopol® ultrez, and Ar = Aristoflex® AVC. The pH, sensory characteristics, weight loss and the viscosity profile of gels were analyzed at times (t) t0, t90 and t180 (24 h, 90 and 180 days after their production, respectively), in ambient temperature...

Fatty chemical composition and antioxidant activities of coconut oils (Cocos nucifera L)

Fixed oils from two cultivars (green and yellow) of solid albumen in the coconut palm (Cocos nucifera), were obtained by a solvent extraction using hexane in three different maturation stages, such as: unripe; ripe and dried. The aforesaid oils were saponified and methylated. Fatty acids and methyl esters were analyzed by the gas chromatography, mass spectrometry (CG-MS). The oils from unripe (green and yellow)...
