The transmitting tissue inBrugmansia suaveolens: immunocytochemical localization of pectin in the style

Two monoclonal antibodies were used to reveal the nature and distribution of pectins in cell walls and in the secretion of the style inBrugmansia (Datura) suaveolens at the light and electron microscope level. The antibodies JIM 5 and JIM 7 distinguish between unesterified and methylesterified pectins. Unesterified pectins occur in the walls of both transmitting tissue and cortex. The high methylesterified pectin is limited to cell walls in the cortex. The intercellular substance contains only unesterified pectins.

Ultrasound assisted extraction of pectin from Trachystemon orientalis L.

Pectin, a natural bio polymer, has wide range of applications in different fields because of its gelling, stabilizing and emulsifying ability as food additive/preservative and drug carrier etc. Main objective of this study was to describe the extraction of pectin for the first time from Trachystemon orientalis L., a medicinal plant grown in black sea region of Turkey. Pectin was extracted from the plant by ultrasound assisted acid hydrolysis method. Obtained pectin was characterized by using ATR-FT-IR and TGA methods. It was observed that the plant contained 2.5% pectin (0.25 g pectin/ per 10 g dried sample). Obtained pectin was labeled as High Methyl esterified Pectin (HMP) as its methoxyl- content was found to be 80% by using titrimetric method. ATR-FT-IR and TGA images were obtained as well. It can be concluded that Trachystemon orientalis L. could be a new source for pectin production for food and pharmaceutical industries.
