Sap on ins 
For convenience, results of the tests for 
saponins have been included in Table 1 under 
three headings : 
Water Alkali L/B 
In the water and alkali columns, means 
froth lasting for more than 30 minutes, and " — ” 
indicates either no froth at all or froth having a 
persistence of less than 30 minutes. A blank in 
any column indicates that no test was done. In 
the L/B column the colour obtained is given. 
Blues are suggestive of steroids, whereas reds 
suggest triterpenoids. 
SUMMARY AND DISCUSSION 
The number of families represented by the 
specimens tested is 54 (within the limits of 
identification available). 
Alkaloids 
The following 32 families contain species 
which give positive tests for alkaloids. In this 
assessment, any score considered marginal has 
been recorded as positive. However, families 
represented by only one species have not been 
included unless the test is clearly positive. The 
first figure is the number of samples found 
positive, and the second figure is the number 
tested.
