Freebase cocaine is essentially pure cocaine that is made today by preparing an aqueous solution of cocaine HCI and adding ammonia or bicarbonate to alkalinize the solution and precipitate alkaloidal cocaine. 6 The "freebase" formed is nonwater-soluble, does not decompose. with heat and can be crushed, and mixed with tobacco and smoked. ❋ Unknown (2010)
Many of these species contain less of these alkaloids than dose Psilocybe cubensis and the alkaloidal content of this species may very in different strains. ❋ Keefe, Patrick Radden (2005)
This theory has also gained great importance as a guide when determining intricate structures, and it has rendered it possible to trace hidden connections within the multifarious group of alkaloidal substances. ❋ Unknown (1964)

It may be found in the urine; gives usual alkaloidal reactions, but no distinctive chemical test known. ❋ Unknown (N/A)
Recent investigations, however, show that there is no alkaloidal material in oats, and whatever stimulating effect they may have results from the nutrients they contain. ❋ Harry Snyder (N/A)
Do oats contain any special alkaloidal or stimulating principle? ❋ Harry Snyder (N/A)
Both plant and animal foods undergo bacterial changes resulting in the production of alkaloidal bodies known as ptomaines, of which there are a large number. ❋ Harry Snyder (N/A)
We may take piperidine and coniine as examples of the methods followed in alkaloidal synthesis; these are pyridine bases. ❋ Various (N/A)
A cup of tea as served at tea tables contains usually only a trace of the alkaloidal principle, but infinitesimal quantities are capable of exerting baneful effects upon some tea drinkers .... ❋ Joel Dorman Steele (N/A)
Another class of bases of an alkaloidal nature, are termed ptomaines; these differ from the leucomaines, being produced by putrefactive or bacterial agency from dead flesh. ❋ A. W. Duncan (N/A)
Meanwhile he fills the cylinder with a solution of a powerful alkaloidal poison, which is easily done by dipping the needle into the liquid and sucking at the small hole near the back end, when the piston will be drawn up and the liquid will follow it. ❋ Unknown (1902)
Since the active alkaloidal and resinoidal principles of roots, barks and gums have been isolated and put in better and more convenient forms, there is no longer need of alcoholic tinctures and elixirs. ❋ Martha Meir Allen (1890)
Coca paste is another form of cocaine that is 60-80percent cocaine sulfate and can also be smoked. 7 The cocaine sulfate is a byproduct of the purification process of cocaine HCI and the paste may contain such impurities as lead, sulfuric acid, kerosene, and methanol. 5 In past years it had been used mainly by inhabitants of coca plant producing countries such as Peru7 but since 1982 has also become popular in the United States. 3 However, alkaloidal cocaine remains the predominant new form in use today. ❋ Unknown (2010)
In relation to the first, it has been suggested that if consciousness be regarded as dependent upon a certain rate of atomic vibration, it is possible that this rate depends on a store of intramolecular oxygen, which, owing to fatigue, may become exhausted; or it may be supposed that alkaloidal substances may collect as fatigue products within the brain, and choke the activity of that organ. ❋ Various (N/A)
"Ptomaines are chemical compounds of an alkaloidal nature formed in protein substances during putrefaction. ❋ Unknown (1908)
It is true that the original package might have been annexed by a clerk, office boy or domestic servant; but the probabilities are that X received the package himself, and this is borne out by the fact that he was able to obtain access to a powerful alkaloidal poison -- such as this undoubtedly is. " ❋ Unknown (1902)
