Effect different sampling times of Ulva sp on polysaccharide sulfate content

Abstract

Ulva sp seaweed generally still harvested from nature, not cultivation. Therefore, guarantee to availability of its seaweed conducted storage in the warehouse. The purpose of this study was to determine the effect of sulfate polysaccharide content on the sampling times of Ulva sp. The sampling time of seaweed raw materials is freshly harvested seaweed, and other has been stored for 4 months. Dried Ulva sp and freshly Ulva sp obtained from Gunung Kidul. The testing parameters include ash content, polysaccharide content, sulfate content, and its yield. The results showed that the highest yield and total polysaccharides were obtained from freshly harvested seaweed, while the sulfate content was similar. Based on the polysaccharide extract test results obtained, storage affects the yield and it content of polysaccharides.
