Abrin is one of the potent toxins isolated from the beans of plant abrus precatorius.the toxic protein consists of two disulfide-bonded subunits,the a and b chains.the b chain is a galactose-specific lectin that facilitates the binding of abrin to the cell membrane that precedes endocytosis.after entering the cells,the a chain catalytically inactivates 60s ribosomal subunits by removing adenine position 4324 of 28s r–rna,and thereby inhibits protein biosynthesis.

Results Twain-80 can increase the solubility. The dimethylsulfoxide, the sorbic acid and acetic acid chlorine can strengthen its bacteriostasis effect. To choice suitable antiseptic temperature and control antiseptic time may enhance furacilin liquid preparation stability. On the contrary, it may reduce the stability when mixing the antioxidants agents such as the sodium hyposulfite and the sodium bisulfite.

Its beneficial widespread effect on health is attributed to sulphur compounds and particularly to thiosulfinates. Odorless and stable, alliin is the most abundant sulfur compound in whole, unbruised Garlic. When the clove of garlic is cut or crushed, the enzyme alliinase is released from its compartment and transforms S-allyl-L-cysteine sulfoxide or alliin into diallyl thiosulfinate allicin, the characteristic compound of garlic flavor. This very unstable thiosulfinate is rapidly degraded to related organosulfur compounds. Allicin is often thought of as the "active ingredient" in Garlic, and has been the subject of numerous scientific studies, but its a fairly unstable compound that likes to react with itself.

蒜氨酸(S-烯丙基-L-半胱氨酸亚砜，alliin)是完整、未受损大蒜里面含量最丰富的硫化物，并且非常稳定，它存在于大蒜的细胞质里；当细胞受损时，蒜氨酸酶从细胞液向细胞质释放，蒜氨酸和蒜氨酸酶接触被迅速转化为一系列新的化合物—蒜辣素及其相似物，蒜辣素(双烯丙基硫代亚磺酸酯，allicin)被认为是大蒜中最重要的活性成分，但它相当不稳定，易于自身反应。
