An active polysaccharide (DHPD1) was isolated from Dendrobium huoshanense.
DHPD1 was shown to inhibit the apoptosis of human lens epithelial cells.
The active core domain of DHPD1 was prepared using pectinase hydrolyzation.
The basic structure features of the core domain of DHPD1 were characterized.
DHPD1 and its core domain prevent cell apoptosis via alleviating cell inflammation.
