Biebsanin — A new susquiterpene lactone fromAchillea biebersteinii andA. santolina
Continuing a study of the lactones of Achillea biebersteinii [i] and A. santolina, from the mother liquors [2, 3] by means of the systems chloroform-ethanol (30:1) and benzene--ethyl acetate (1:1) we have isolated a new chlorine-containing sesquiterpene lactone with the composition C15HzgO~CI (ethyl acetate), mp 258-259°C (in a preheated metal block), [u]~ ° --34 ° (c 1.0; pyridine), M + 330, which we have called biebsanin (I).
Rupicolin-A and -B, rupin-A and -B, and cumambrin-B oxide from Artemisia tripartita ssp. Rupicola
Abstract Five new sesquiterpene Iactones have been isolated from Artemisia tripartita Rydb. ssp. rupicola Beetle. The compounds, all guaianolides, are structurally related in what appears to be a sequence in which epoxidation plays the principal role.
THE RELIGIOUS SITES DURING THE CHINESE CULTURAL REVOLUTION, 1966-1976
This study presents a thought-provoking picture of statistical data regarding the growth patterns of the religious sites for five main Chinese religions during the Cultural Revolution from 1966 to 1976. Applying comparative and quantitative lenses, this paper addresses the diE™erent growth rates of religious sites during the four diE™erent periods from 1949 to 2004 to test the relative growth pace of religious sites during the Cultural Revolution. To understand the patterns of growing religious sites from 1966 to 1976, this study also compares the diE™erent growth rates of religious sites between the first phase (1966 to 1970) and the second phase (1971-1976) of the Cultural Revolution. Furthermore, it provides detailed information concerning the year of building new religious sites for all five major religions that hold more than 2,500 new religious sites during the Cultural Revolution. In addition, the study shows the top five provinces which built the most new religious sites while denoting their respective rural and urban locations in an eE™ort to demonstrate their geographical expansion during the period. Finally, this study addresses the growth rates of the national population and per capita GDP as compared to the growth of the religious sites during the period of national disaster (1966-1976).
