2. State Key Laboratory of Natural and Biomimetic Drugs， School of Pharmaceutical Sciences，Peking University， Beijing 100191， China； 3.Medical College， Yangzhou University， Yangzhou 225009， China)[Abstract]Compounds were isolated through various chromatographic techniques and their structures were identified by spectroscopic data analysis and comparison with those reported in the literatures. Thirteen compounds were obtained from the petroleum ether and ethyl acetate extracts. Their structures were identified as 4，4′-dimethoxy-9，9′，10，10′-tetrahydro-(l，l′-biphenanthrene)-2，2′，7，7′-tetrol (1)， 4，4′，7，7′-tetrahydroxy -2，2′-dimethoxy-1，1′-biphenanthrene (2)， 3， 5-dihydroxy-2， 4-dimethoxyphenanthrene (3)， physcion (4)， chrysophanol (5)， emodin (6)， genkwanin (7)， quercetin (8)， quercetin 3′-O-β-D-glucopyranoside (9)， 3-methoxy-4-hydroxy phenylethanol (10)， syringic acid (11)， vanillin (12)， and p-hydroxybenzaldehyde (13)， respectively. Compounds 1-3 and 5-12 are reported from this genus for the first time.
