Application

Larch Arabinogalactan, a plant-derived biopolymer, is an excellent dietary fiber that has been shown to increase the production of short-chain fatty acids, principally butyrate and propionate, and to decrease the generation and absorption of ammonia. Larch arabinogalactan can stimulate natural killer (NK) cell cytotoxicity, enhance other functional aspects of the immune system, and inhibit the metastasis of tumor cells to the liver.

Biochem/physiol Actions

Dietary fiber that enhances immune system function by stimulating natural killer (NK) cell activity.

Water-soluble high molecular weight compounds were isolated in yields of 21-22% from the oleogum of Boswellia serrata and B. carteri. Using anion exchange chromatography and gel permeation chromatography, different proteoglycans were purified and characterized, leading to four principally different groups:
