    Journal: Zhong Yao Cai; 2014 Dec; 37(12):2201-3. PubMed ID: 26080502.
    Abstract:
    OBJECTIVE: To study the chemical constituents of the leaves of Psidium littorale. METHODS: The constituents were isolated with silica gel column chromatography and the structures of these compounds were elucidated on the basis of spectral analysis. RESULTS: Four megastigmane glycosides and three lignans were isolated and their structures were identified as Bridelionoside B(1), Euodinoside E(2), (3S,5R,6R,7E,9S)-Megastignan-7-ene-3,5,6,9-tetrol 9-O-β-D-glucopyranoside (3), Bridelionoside C(4), (--)-Isolaricires-inol 3-α-O-β-D-glucopyranoside (5), (--)-5'-methoxy-Isolariciresinol 3-α-O-β-D-glucopyranoside (6) and dihydrodehydrodiconiferyl alcohol 4-O-β-D-glucopyranoside(7). CONCLUSION: Compounds 1-7 are isolated from this plant for the first time. The results have provided the scientific basis for further exploitation of Psidium littoratle.
