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 colonial ethnological line: Timor and the racial geography of the Malay Archipelago
This article examines the connected histories of racial science and colonial geography in Island Southeast Asia. By focusing on the island of Timor, it explores colonial boundaries as modes of arranging racial classifications, and racial typologies as forms of articulating political geography. Portuguese physical anthropologist António Mendes Correia's work on the ethnology of East Timor is examined as expressive of these productive connections. Correia's classificatory work ingeniously blended political geography and racial taxonomy. Between 1916 and 1945, mainly based on data from the Portuguese enclave of Oecussi and Ambeno, he claimed a distinct Malayan racial type for the whole colony of ‘Portuguese Timor’. Over the years he developed an anthropogeographical theory that simultaneously aimed to reclassify East Timor and to revise the racial cartography of the Malay Archipelago, including Wallace's famous ethnological line.
