New Phenylpropanoid Glycoside from Boschniakia rossica

From the whole plant of Boschniakia rossica (Cham. et Schlech.) Fedtsch. et Flerov., a new phenylpropanoid glycoside (2) was isolated together with fourteen known compounds which include two phenylpropanoid glycosides [rossicaside B (1) and rossicaside A (3)], triandrin (4), boschniakinic acid (5),two iridoid glucosides [boschnaloside(6), 8-epideoxyloganic acid (7)], three triterpenoids [3-epioleanolic acid (8), 3-epiacetyloleanolic acid (9), oleanolic acid (10)], β-sito-sterol (11), and four iridoid aglycones [1,10-bisdeoxy-7,8-dihydrogenipin (12), 7-methyl-octahy-dro-cyclopenta [c]pyran-4-carboxylic acid (13), (1R) and (1S) 1-O-methyl-8-epideoxyloganic acid aglycone (14, 15)].
