RÉSUMÉ
The early period of Sino-American communication in Chinese materia medica referred to the historical period from the 17th century, European trade overseas and the frequent communication of missionaries, to 1848 when gold prospectors from China travelled to America. This paper reviewed and examined the three historical events in this period : the spread, trade, and introduction of tea; the first edition of the United States Pharmacopoeia and its collection of Chinese medicines and preparations; and the discovery and trade of American ginseng hoping to explore the basic historical facts of the spread and exchange of Chinese medicine between China and America in the early period. The paper explored these historical factors, provided effective references for developing cooperation in public health between China and America and the start of the constructing of a Global Community of Health for All.

Many species of genus Hedyotis (Rubiaceae) were used as folk medicine for treatment of cold, inflammation, cancer and etc. in China. The alcoholic extract of the whole plant of H. chrysotricha showed good hepatoprotective effects. From the alcoholic extract ten iridoids were isolated and their structures were elucidated as: asperuloside (1), scandoside methyl ester (2), asperulosidic acid (3), deacetyl asperulosidic acid (4), loganin (5), deacetyl asperuloside (6), acetyl scandoside methyl ester (7), 6 beta-hydroxy-genipin (8) and two new compounds named hedyoside (9) and 6'-acetylasperuloside (10), by means of chemical and spectral methods.

The root and rhizoma of Rhodiola fastigita S. H. Fu. is a traditional Tibetan medicine used for promoting blood circulation and relieving cough. In recent years, it was generally used as a tonic. So, its chemical constituents were studied. A new flavonoid and six known compounds were obtained. The known compounds were: 4'-methoxyl herbacetin (I), rhodiolin (II), dihydrokaempferol (III), daucosterol (IV), tyrosyl (V) and salidroside (VI). The structure of the new flavonoid was elucidated as herbacetin-8-O-alpha-D-lyxopyranoside (VII), by means of UV, IR, MS, 1H and 13C-NMR spectral data and chemical methods.

Five compounds were isolated from the rhizome of Rhodiola kirilowii. Based on spectral studies and chemical analysis the structures were established as tyrosol, daucosterol, lotaustralin, salidroside and sucrose.
