title: Akaloid screening. VII.
abstract: One thousand and five plant extracts were screened for the presence of alkaloids. The number of positive tests obtained was 190, or 18.91%. There were 153 species found to contain alkaloids that are new to the literature. In the six previous communications (1-6) we have reported on the screening of 5,995 plant extracts for alkaloids. These extracts represented 4,888 species of plants, of which 1,336 gave positive alkaloid tests.
