Development of W/O/W emulsion with gallic acid in the internal aqueous phase.

The aim of this work is to develop a W/O/W multiple emulsion with gallic acid in the internal aqueous phase (W). A quantification method for gallic acid using HPLC-UV was developed and validated. In the first step, a simple W/O emulsion was prepared with distilled water, polyglycerol polyricinoleate, sodium chloride, gallic acid and pH 5.

Anatomy, micromorphology, and histochemistry of leaves and stems of Cantinoa althaeifolia (Lamiaceae).

This article enumerates the detailed anatomy of Cantinoa althaeifolia (Lamiaceae) illustrated with light and scanning electron microscopy images. The anatomical markers include the presence of branched nonglandular trichomes and capitate, peltate, and clavate types of glandular trichomes; prismatic crystals on the leaf and stem surfaces; and oil droplets in the leaf mesophyll. Histochemical tests and EDS analyses were performed in order to detect the composition of certain cells and their contents.

Antinociceptive and Anti-Inflammatory Effects of Bixin, a Carotenoid Extracted from the Seeds of Bixa orellana.

Bixin is the main natural apocarotenoid extracted from the seeds of widely used as a cosmetic and textile colorant. Despite the description of several pharmacological properties of extracts, little has been studied regarding the pharmacological properties of bixin. Then we aimed to investigate the potential anti-inflammatory and antinociceptive effect of bixin in preclinical models of inflammation and acute pain.
