Sixteen flavonoids (1-16) including two new ones, named officinoflavonosides A (1) and B (2) were obtained from the aerial parts of Rosmarinus officinalis. Among the known ones, 6, 10, and 13 were isolated from the rosmarinus genus for the first time. Their structures were elucidated by chemical and spectroscopic methods. Moreover, the effects on sodium(More)
Astragalus membranaceus is a Traditional Chinese Medicine (TCM) belonging to the Leguminosae family. It has been used as antidiabetic, cardioprotective, and hepatoprotective in the TCM clinic. From the stems of A. membranaceus (Fisch.) Bge. var. mongholicus (Bge.) Hsiao, 14 oleanane type saponins (1-14) including eight new ones, astroolesaponins A (1), B(More)
Twelve cyclolanstane-type saponins including six new ones, astrolanosaponins A1 (1), A2 (2), B (3), C (4), D (5), and E (6) were obtained from the stem of Astragalus membranaceus (Fisch.) Bge. var. mongholicus (Bge.) Hsiao, and their structures were elucidated by chemical and spectroscopic methods. Of the known ones, cycloastragenol-3-O-β-D-glucopyranoside(More)
Five new compounds, gentixanthones A1 (1), A2 (2), and gentichromones A1-A3 (3-5), together with thirteen known xanthones (6-18) were obtained from the whole plants of Gentianella acuta (Michx.)

Eight new compounds, dioscorosides G (1), H1 (2), H2 (3), dioscorol B (4), dioscorosides I (5), J (6), K1 (7), and K2 (8), together with twelve known ones (9-20) were obtained from the rhizomes of Dioscorea septemloba. Their structures were elucidated by chemical and spectroscopic methods. Among the known isolates, 12-14, 18, and 20 were isolated from the(More)
Dammarane-type triterpenoids (DTT) widely distribute in various medicinal plants. They have generated a great amount of interest in the field of new drug research and development. Generally, DTT are the main bioactive ingredients abundant in Araliaceae plants, such as Panax ginseng, P. japonicas, P. notoginseng, and P. quinquefolium. Aside from Araliaceae,(More)
Four new aromatic constituents, astraflavonoids A (1), B (2), C (3), and astramemoside A (4), along with sixteen known ones 5-20 were obtained from the stems of A. membranaceus (Fisch.) Bge. var. mongholicus (Bge.) Hsiao. Their structures were elucidated by chemical and spectroscopic methods. Among the known isolates, 14 was obtained from the Astragalus(More)
The 70% ethanol extract of Dioscorea septemloba rhizomes was subjected to chromatographic columns including silica gel, ODS, D101 resin, Sephadex LH-20 and HPLC, to yield three new diarylheptanoids (1-3) and two novel stilbenes (4 and 5), together with six known ones (6-11). Their structures were elucidated on the basis of extensive 1D NMR (1H and 13C), 2D(More)
