Alkaloids substances

Although no experiment has yet been reported to support the idea, it seems clear that a majority of the pyrrolidine alkaloids arise from the ornithine, pu-trescine, and proline pool. This could be the case for ficine (61) and isoficine (62), vochysine (63), and phyllospadine (64) but also of the Darlingia alkaloids, which share common features with hygrine this assertion probably also holds for the ruspolinone (25) and odorine-roxburghlin (59) families. Peripentadenine, isolated from a plant of the family Elaeocarpaceae, bears resemblance to other alkaloids of the elaeocarpus type such as isoelaeocarpicine (124) (161). It cannot be excluded, however, that spermidine may be a biosynthetic intermediate instead of putrescine. The question of the origin of ant alkaloid substances remains so far without an obvious answer. 

The regulation of Na+ ions and channels are the means for possible correction of abnormalities in tissue functioning and ganglic integrations. However, it is necessary to pay attention to the possible unwanted side effects. Alkaloids are complex agents. Smaller doses are safer when considering cell toxicity or other possible metabolic effects. Alkaloids and alkaloidal substances should be given serious consideration and precautions before use.

An interesting group of alkaloid substances, not previously discussed in these volumes, are the polyamine alkaloids they are reviewed in a chapter entitled Putrescine, Spermidine, Spermine, and Related Polyamine Alkaloids. Recently available books on alkaloids of a general nature, primarily intended for students of natural products, are not going to replace a treatise that continues to be detailed, complete, and up-to-date. 

Two bases found in barley germs and in ergot are closely related compounds. Ergot is a fungus growth occurring on cereals, especially rye. From it several alkaloid substances have been isolated. One of these has been shown to be para-hydroxy phenyl ethyl amine. 

F.). It is attended by the breaking down and liquefaction of the material if it be solid or its clouding and the formation of a scum upon the surface if it be liquitl.

These groups do not contain any alkaloidal substances, and need not be further considered. 

However, the early investigations of Lewin (13-16), Heffter (17-23), and Heyl (24, 25), and the more recent ones of Herrero-Ducloux (26-30), Reti (2-4, 31-36), and others, seem to indicate that the faculty of producing and storing alkaloidal substances should be considered one of the characteristics of this botanical family.
