Study on the Distribution of Polysaccharide, Polyphenols, and Flavonoids from Different Organs of Rattan

In this study, Rattan (palm cane) as the raw material, the different parts of Rattan plant were extracted by homogenate-assisted extraction, and then extracted by water heating stirring extraction and reflux extraction with 80% ethanol, respectively. The extraction yields of aqueous extractives and alcohol extractives from different parts of Rattan, and polysaccharides, polyphenols and flavonoids content in aqueous extractives and alcohol extractives were determined. And the details of the homogenate-assisted extraction mechanism were interpreted. The experimental results showed that the polysaccharide content in the pericarp (29.31%) and sarcocarp (7.27%) was the highest, and in the tender stems (12.14%) was less, and in sheath, blade, and rattan stem were 2.91%, 1.87% and 1.99%, respectively. However, the polyphenols and flavonoids content in alcohol extractives was higher, which in the pericarp (polyphenols 5.33%, flavonoids 4.67%) and sarcocarp (polyphenols 5.22%, flavonoids 4.64%) was the highest, and followed by blade (polyphenols 3.35%, flavonoids 2.92%), sheath (polyphenols 2.68%, flavonoids 2.37%), and tender stems (polyphenols 1.97%, flavonoids 1.83%), and in the rattan stem (polyphenols 0.55%, flavonoids 0.47%) was the least.
