circulation and the treatment of rheumatoid arthritis. The investigation of the roots and stems of Schisandra rubriflora led to the isolation of 29 compounds, including 10 novel nortriterpenoids, rubriflorlactones A–J (1–10). Some compounds were tested for their anti-HIV-1 activity and two of them show anti-HIV-1 activity with SI values more than 10.

Phytochemical Study on Chemical Constituents and Bioactivities

from the fruits of Schisandra rubriflora

Phytochemical study on the fruits of Schisandra rubriflora(Franch.) Rehd.et Wils resulted in the isolation of 10 compounds. Among them, compound 1 was elucidated to be a new lignan and compound 2 was isolated firstly as a natural product. All structures were determined on the spectral evidences. Some compounds were tested for their anti-HIV-1 activity and two of them show obvious anti-HIV-1 activity with SI values more than 34.

of Angelica apaensis

Angelica apaensis, belonging to the family Umbelliferae, is a kind of perennial herb widely distributed in the northeast of Yunnan, China. The roots of this plant have been extensively used as folk medicines for the treatment of tympanites, cough, asthma, wind colic and flatulency. We have investigated the roots of Angelica apaensis and herein report the isolation of 37 compounds, including 2 new coumarin glucosides. All compounds were tested for their anti-platelet aggregation activity and none of them have obvious activity.
