%X Examination of a large number of samples of Duboisia hopwoodii has confirmed the findings of Bottomley, Nottle, and White (1946). The methods used for the estimation of nicotine and nornicotine are described and the results summarized. These could not be correlated with locality, season, or soil type, and examination of fresh leaves showed that the alkaloid content is considerably reduced on drying.     Samples of nicotine and nornicotine have been prepared and ursolic acid and a quercetin glycoside have been isolated from D. hopwoodii leaves.
