title: Two new chlorinated naphthalene glycosides from Rumex patientia.
abstract: Two new naphthalene derivatives, named patientosides A (1) and B (2), were isolated from the roots of Rumex patientia. The structures of the new compounds were established as 2-acetyl-4-chloro-1,8-dihydroxy-3-methylnaphthalene-8-O-beta-D-glucopyranoside (1) and 2,4-dichloro-1,8-dihydroxy-3-methylnaphthalene-8-O-beta-D-glucopyranoside (2) by means of spectroscopic methods.
