Abstract
Phytochemical investigation of the roots of Streptocaulon griffithii afforded a novel dipeptide, streptin (1), a new hemiterpenoid, (R)-3-ethyl-4-methylpentyl-β-rutinoside (2), and a new disaccharide, 1-methoxyl-4-O-β-glucopyronosyl-β-digitoxose (3), along with five known compounds. Their structures were identified by spectroscopic methods and comparison with literature values.
