§ 03026 α– Glycosyl–isoquercitrin 
Synonyms Enzymatically modified isoquercitrin ；isoquercetin ；EMIQ
Formula weight  ～800 
Structural formula 
 
  
Definition The starting product, rutin, firs t enzymatically converted to 
isoquercitrin. Subsequently, an aqueous solution of 
isoquercitrin and dextrin is treated with cyclodextrin 
glucanotransferase to a dd glucose units, forming α– 
glycosyl–isoquercitrin. 
Assay  After drying, it should contain no less than 60 % (as rutin, 
C27H30O16). 
Description Yellow to yellowish brown powder with a slight 
characteristic scent 
Identification  1. 5 mg of the sample is dissolved in 10 mL of water. 
When 1～2 drops of ferric chloride solution (1 →50) are 
added to this solution, it becomes brown in color. 
2. 5 mg of the sample is dissolv ed in 5 mL of water, where 
2 ml of hydrochloric acid and 0.05 g of magnesium 
powder are added. The color of the solution changes to 
orange～red color. 
3. 0.1 g of the sample is dissolved in 100 mL of 1 N 
sulfuric acid. When this solution is boiled for 2 hours 
and cooled, yellow precipitates are formed. 
4. Spectrophotometry: 10 mg of the sample dissolved in 
500 mL of phosphoric acid solution (1 →1,000) shows 
an absorption maximum at approximately 255 nm and 
 3350 nm. 
5. Thin layer chromatography: th e main spot in the test 
solution has the bigger Rf valu e than that of the main 
spot of lutin solution.

oxyethylene groups, equivalent to not less than 96.5 and

approximately 20 moles of ethylene oxide（ C
2H4O）for 
each mole of sorbitol and its mono- and dianhydrides. It is 
a yellow- to orange-colored, oily liquid having a faint, 
characteristic odor and a warm, somewhat bitter taste. It is 
very soluble in water, producing an odorless, nearly 
colorless solution, and is solu ble in alcohol, in fixed oils, 
in ethyl acetate, and in toluene.  
Identification 1. To 5 mL of a 1 in 20 solution add 5 mL of solution hydroxide TS, boil for a few min, cool, and acidify 
with diluted hydrochloric acid TS. The solution is 
strongly opalescent. 
2. To a 1 in 20 solution add bromine TS, dropwise. The 
bromine is decolorized.
