Metabolism and Calcium Antagonism of Sodium Alginate Oligosaccharides

Bioscience, Biotechnology, and Biochemistry, 2007
Sodium alginate oligosaccharides (NaAOs) consisting of a mixture of eight oligosaccharides have previously been reported to lower blood pressure. We investigated in this study the excretion of NaAOs into the urine or feces, and attempted to elucidate the mechanism for lowering blood pressure by using isolated mesenteric arteries from the rabbit.

Antihypertensive Effects of Sodium Alginate Oligosaccharides.

Journal of the agricultural chemical society of Japan, 2001
Two types of alginate oligosaccharides (Na-AO and K-AO) were prepared by cleavage of alginate polysaccharide with alginate lyase. In this study, the effects of these oligosaccharides on blood pressure of spontaneously hypertensive rats (SHRs) were investigated. In the Na-AO experiment, Na-AO and NaCl groups were fed a normal diet (CE-2, Clea Japan Inc.)
