Chemical characterization of the immunomodulating polysaccharide of Aloe vera L.

This paper describes a selection of the ethnoveterinary medicines used for herd dogs in the southern regions of Ilam province, Iran. Traditional botanical medicine is the primary mode of healthcare for most of the rural population in Ilam province. In this study, a questionnaire was distributed among 45 residential areas in 22 rural zones of the southern areas of Ilam province. The objective of this study was the recognition of natural medicinal methods using medicinal plants, and the classification of ethnoveterinary applications and collection of domestic science. Twenty-two medicinal plants from 16 families were identified. The main application of these plants was for the detection and treatment of digestive disorders using Citrullus colocynthis, Aristolochia clematis, Scrophularia deserti, Quercus brantii, Ceracus microcarpa, Echium strigosa, Pistacia atlantica, and Pistacia khinjuk which have been applied using Euphurbia graminifolius, Peganum harmala, Salsola rigida, Artemisia herba-alba, Amygdalus arabica, jolbak of salt water, Peganum harmala L., and Nicotina tabacum for external and internal parasite disorders. S. deserti for ophthalmic disorders, and P. atlantica, P. khinjuk, and Q. brantii for respiratory disorders were applied. The present study confirmed the traditional medical effects of some plants and revealed the unique medical effects of other plants, which if recognized could be useful in the creation of new ideas and increasing knowledge for the modern pharmaceutical industry. Since very few clinical trials have been conducted on plants native to Ilam province, it is necessary that more research be conducted to ensure that labeled and standardized products are introduced for human consumption.

“…Waller et al (1978) had worked on sugar analysis of A. vera gel and reported highest proportion of Mannose (39.4 μmol/g), which was the main component for biologi-cal activity. The polysaccharides containing glucomannans, mannans and pectins of different molecular weights of aloe vera are responsible for their biological activities in vivo, as well as in vitro (Yaron 1993;Chow et al 2005). Glucomannan is a good moisturizer and mainly used in many cosmetics products (Henry 1979), whereas acemannan, the major carbohydrate fraction in the gel, is a water-soluble long-chain mannose polymer, which accelerates wound healing, modulates immune function and antiviral effects.…”

In this investigation, leaf-splitting unit was designed and fabricated for Aloe vera gel expulsion machine. The splitting unit consisted of grip roller, reciprocating blade, rotary disc and eccentric drive. The rotary motion was converted into the reciprocating drive with slanted rotary disc mounted on shaft. The grip roller was covered with spongy material to hold the A. vera leaf without breaking rind. The design parameters included were grip roller dimensions and speed, stroke of reciprocating blade and size of rotary disc. The leaf was inserted between two grip rollers and splitting into two halves carried out by reciprocating knife. The splitting unit was tested for different speed of grip expulsion roller and leaf thickness. It was concluded that for getting maximum gel recovery, minimum residual gel percentage, highest expulsion efficiency and output capacity, the leaves should be split in splitting unit and the A. vera gel expulsion should be carried out at 75 rpm roller speed for 25-30-mm thickness of A. vera leaves. PRACTICAL APPLICATIONSGel extraction from A. vera leaves is important process as it is used as preservative coating, food drinks and cosmetics. Squeezing of A. vera leaves leads mixing of compounds from leaf skin and deteriorates the quality of gel. The leaf-splitting process is necessary to reduce the contamination of inner A. vera gel during gel expulsion by preventing ingress of chemical ingredients from leaf skin and maintain its cosmetic and nutritional values. The developed leaf-splitting unit would reduce manual contact and minimize the processing time to get good quality gel from A. vera leaves without contamination. bs_bs_banner Journal of Food Process Engineering
