The following chromatographic analyses of dried 1xbut 
leaves from Guatemala City, Guatemala, were reported by the 
chemical research laboratory of SISA Incorporated of Cam- 
bridge, Massachusetts, on August 21, 1979: 
EXTRACTION OF EUPHORBIA LANCIFOLIA (IXBUT) 
In order partially to characterize some of the principles of 
Euphorbia lancifolia, an extract of dried ixbut leaves was 
prepared and the extract subjected to gas-liquid chromatogra- 
phy (figure 1) and high pressure liquid chromatography (figure 
2). 
The gas-liquid chromatographic analytical method separates 
the components of the extract primarily on the basis of their 
volatility with the most volatile materials appearing first. 
The high pressure liquid chromatographic analytical method 
separates the components primarily on the basis of polarity. 
With a ‘‘reverse phase’ column of the type used here, the more 
polar components appear early on the chart. 
Since in both of these methods each peak on the chart corre-
