Some antimicrobial metabolites leached from the surface of leaves are known, namely, sclareol (182) and isosclareol (183) from Nicotiana glutinosa parthenolide (184) from Chrysanthemumpartbenium,1 6 and rugosal A (185) from Rosa rugosa,wl and so on. The possible roles of these compounds in host—pathogen interactions are discussed in the original papers. 

For studies on the interrelationsship among nicotine, nornicotine, anabasine and anatabine during the biosynthesis in Nicotiana glutinosa, Alworth and Rapoport used almost the same gas chromatographic conditions as reported above. On a polybutylene glycol column the alkaloids mentioned were satisfactorily resolved.

Nicotiana Alkaloids.—Experiments with C02 have also been used in consideration of the origin of the pyridine ring of nicotine (27) and correlated with similar work on the pyrrolidine ring of this alkaloid. When Nicotiana glutinosa... 

In a recent study,[2- " C]lysine was fed to Nicotiana glutinosa, and although it was specifically incorporated into anabasine (3) in the expected manner it did not label the anatabine (8), thus according with the previous result. 

It is an antifungal sesquiterpenes induced in leaves of Nicotiana glutinosa following infection with tobacco mosaic virus (TMV). The compound could not be detected in inoculated leaves. Its isolation2 was achieved by Burden and coworkers. Young plants (6-8 weeks old) of N-glutinosa with 4-5 fully expanded leaves in aqueous suspension were inoculated with... 

The biological investigations on capsidiol show that the results obtained are very similar to those obtained with various legumes74 and with Nicotiana glutinosa. These results provide further evidence that tissues which are necrotic as a result of infection with virus generally contain antifungal compounds. Therefore probably from sweet pepper capsidiol was isolated71 as phytoallexin. Thus capsidiol may have similar...

Pyrrolidine Alkaloids.—and tracer feeding results are in conflict for the biosynthesis of the pyrrolidine ring of nicotine. On the one hand ° [2- C]lysine afforded nicotine (138) with equal labelling of C-2 and C-3, whereas on the other the alkaloid obtained after exposing Nicotiana glutinosa plants to C02 was found to be more heavily labelled at C-4 and C-5 than C-2 and C-3 other workers have found uniform labelling of the pyrrolidine ring after application of... 

Synthetic methods for pyrrolidines as well as A - and A -pyrrolines have been surveyed. Some un-natural C-labelled pyrrolinium salts have been prepared in connection with biosynthetic work in Nicotiana glutinosa (see Section 3). 

Some varieties of Nicotiana glutinosa produce a protein called AVF which afford some protection against TMV by restricting its lesions in an analogy manner to interferons [11]. AVF Is a glycoprotein which is terminally phosphorylated with 22,000 daltons molecular weight. The mechanism of action of AVF is not yet established.
