D-Glucuronolactone CAS 32449-92-6 is prepared by lactonization of glucuronic acid (see the previous article): starch is oxidized with nitric acid and then hydrolyzed to obtain a glucuronic acid concentrate, mixed with glacial acetic acid, and lactonized under reduced pressure at 60-65°C (5.32-14.6kPa). At the same time, the acetic acid is recovered, and the reaction material is cooled and left for 6-8 days to crystallize glucuronic acid lactone. It is recrystallized with ethanol water solution and decolorized and refined by sharp carbon to obtain the finished product.

D-Glucuronolactone ( also known as D-Glucurono-3,6-Lactone) is an important nutritional supplement for human health. It has two main functions for human:  Energy enhancer & Liver protection. As a health care product, it is a white crystal or crystalline powder, soluble in water, alcohol, antistat, methanol and acetone, slightly soluble in ether and chloroform.

Glucuronolactone can be used as Nutritional supplements, healthcare supplements, health food additives, pharmaceutical raw material.
1) Glucuronolactone is a naturally ooccurring chemical produced by the metabolism of glucose in the human liver. It is an important structural component of nearly all connective tissues. Glucuronolactone is also found in many plant gums.
2) Glucuronolactone is rapidly absorbed and metabolised into non-toxic metabolites such as xylulose. In addition, humans may be able to use glucuronolactone as a precursor for ascorbic acid synthesis. According to "The Merck Index", it is also used as a detoxicant.
3) Glucuronolactone is a popular ingredient in energy drinks with claims that it detoxifies the body. Although levels of glucuronolactone in energy drinks can far exceed those found in the rest of the diet, the European Food Safety Authority (EFSA) has concluded that exposure to glucuronolactone from regular consumption of energy drinks is not a safety concern (No Observed Adverse Effect Level of glucuronolactone = 1,000mg/kg/day). A fatality was reported after intake of 1420 ml of an energy drink.
