Brief Introduction
Aloe, native to Africa, is also known as "lily of the desert", the "plant of immortality", and the "medicine plant". The name was derived from the Arabic alloeh meaning "bitter" because of the bitter liquid found in the leaves. In 1500 B.C. Egyptians recorded use of the herbal plant in treating burns, infections and parasites.
There are over 500 species of aloe growing in climates worldwide. Ancient Greeks, Arabs and Spaniards have used the plant throughout the millennia. African hunters still rub the gel on their bodies to reduce perspiration and their scent.

Standard preparation :
Weigh accurately about 10 mg of polydatin Working Standard (W1) in 25ml volumetric flask, dissolve and make up the volume with methanol.
Sample preparation:
Weigh accurately 10 mg(W2) of test sample and Transfer the sample to previously dried 25ml volumetric flask, add methanol to dissolve then make up the volume with methanol.
Procedure:
Separately inject equal volume (20µl) of the standard preparation and the test preparation into chromatogram in the triplicate and note down the area counts of Aloe E xtract peak calculate the percentage of Aloe E xtract .
Calculation:
Aloe Extract (%)w/w = At x W1 Ps100%
Where, As W2
At and As are the counts of Aloe E xtract peak in the chromatograms of the test preparation and standard preparation respectively. Ps is the contents of Aloe E xtract in standard.
