Abstract
The total choline content of 74 kinds of vegetables and mushrooms commonly used in Japan were determined.The purity of the choline reineckate obtained from plant materials was tested by piper chromatography.after hydrolysis with nitric acid The results were as follows:
1) Mushrooms, pulse crop, and herbage crops were generally rich in choline, especially, cauliflower (71.1mg%) and brussel sprout (83.6mg%) contained larger amounts of choline than other vegetables.
2) Arrow head, taro, yam, bambooshoot, and mushrooms, which are known as Asthmogene Nahrung, contain a large amount of choline.
3) The navel of broad bean contained 308mg%, therefore it was found that the choline content was the largest of all the plants examined.
4) The pureness of the choline reineckate obtained by this determination method, though there were a few exception, was further ascertained by paper chromatographic test.
