The beta-sitosterols is a kind of physiological activity material. It has wide range utilities in medicine, cosmetics, animal growing, paper manufacture, printing, textile, food field and etc.

The beta-sitosterols has an important role of physiology action in body, which restrains adsorbing of gall steroids, and restrain biochemistry composing of gall steroids, the phtosterol also has strong freighting inflammation, which can prevent and treat heart disease, atherosclerosis, ulcer, skin disease, cancer of womb etc. The beta-sitosterols has effect of healing wound, growing from gallstone, and is important raw material of Vitamin D3 and medicine of steroids.

The beta-sitosterols has good permeability to skin. It keeps skin wetness, improving metabolism of skin and preventing skin inflammation, It has effect to prevent skin aging and crythema, which is caused by sun polarized light, It also helps to grow hair and condition hair, served as W/O emulsifier in cosmetics, it has good endurance and feeling in use (mild, soft ), and no deterioration.

The beta-sitosterols has good resistance to oxidation. So it is a kind of food antioxidant-and nutrient additives. It is also the raw material of animal growth substance, improving not only growing up, but also health.

1.High selectivity and sensitivity. The pseudo-positive rate of the measuring results is much lower than other enzymes. The mono-molecular actylcholine esterase is highly sensitive and can be selectively inhibited by organophosphor and carbamate. Since the AchE with different origin differs in sensitivity, selecting sensitive housefly as extract objection and breeding it will further improve its sensitivity to reagents.

2.Convenient use and low cost. It overcomes the difficulty in storing enzyme at room temperature and has a protracted room storage life of 15d with a loss of activity less than 5%. It is small-packaged and easy to carry about.

3.Practical usage: First, extract sample with buffer solution carried on the reagent kit, then mix the extractive with enzyme solution followed with 5-minute reaction, react with substrate and developed reagent for 10min, contrast the chromaticity with portable colorometric card and then quantitatively determine pesticide remnant in sample by inhibition rate of enzyme activity.
