3 Methodology

Aloin, also known as aloin or aloe-emodin, English name Aloin or Barbaloin, molecular formula C21H22O9. Aloe products Aloin is present as a mixture of optical isomers aloin A and B. This standard evaluates the content of aloin A and B as a mixture The aloe glucoside index of the product. In this method, the sample is dissolved in methanol, vortexed, ultrasonically extracted from the aloin, centrifuged and filtered to take the supernatant with UV The detector or diode array detector is analyzed by high performance liquid chromatography and quantified by the peak area external standard method.

4 Reagents and materials

Unless otherwise indicated, only analytically pure reagents and primary water specified in GB/T 6682-2008 shall be used in the analysis. 4.1 Methanol. Chromatographically pure. 4.2 Acetonitrile. Chromatographic purity. 4.3 Glacial acetic acid. Chromatographically pure. 4.4 1% glacial acetic acid (volume ratio). 1 mL glacial acetic acid 99 mL water. 4.5 The purity of aloin A reference substance is ≥98%, CAS number. 1415-73-2; the purity of aloin B reference substance is ≥98%, CAS number. 28371- 16-6.

5 Instruments and Equipment

5.1 High performance liquid chromatograph. equipped with UV detector or diode array detector. 5.2 Electronic analytical balance. accuracy 0.0001g. 5.3 sonicator. 5.4 Multiple Swirl Oscillators. 5.5 High-speed centrifuge. speed ≥ 10000r/min. ......
