Two dimensional chromatography of the sun dried Jessenia 
Bataua leaf material gave the following pattern of major pheno- 
lic compounds. (Figure 1)

FIGURE |. 2-dimensional chromatogram of ultra-violet fluorescent spots of flavo- 
noids and related compounds in Jessenia Bataua. 
From their fluorescence under ultra-violet light and their 
position on the chromatogram, it is believed that compounds 
1-3 are flavonol glycosides: 4-5 flavone glycosides: 6 an un- 
known cinnamic acid and, compounds 7-8 isomeric forms of 
caffeic acid and p-coumaric acid derivatives respectively. Fur- 
ther investigations on the identity of these compounds is at 
present underway. 
The 2-dimensional paper chromatograms showed that the 
following compounds were present in the various leaf extracts 
(Table 2). 
The 2-dimensional paper chromatograms of the solutions in 
which the leaves had been soaked showed that the following
