Introduction of medicinal materials

saute

This product is OBTAINED by steam distillation FROM FRESH STEMS AND leaves OF MINT, and THE yield is generally 0.3%-0.6%. Peppermint oil refrozen, partially

After removing 45%-55% menthol, the volatile oil obtained is menthol oil. Peppermint OIL IS USUALLY fractionATED TO REMOVE THE FIRST AND LAST OIL FRACTIONS. This operation is characterized by a high degree of deformability, forming different styles of peppermint oil. Fractions of peppermint oil removed to a greater extent are sometimes referred to as deciterpene oil.

character

This product is light grass green liquid or light yellow clear liquid. When slightly cooled, it solidifies into a solid. Strong mint aroma with a cool, slightly bitter taste. Over time, the color gradually deepens. This product can be mixed freely with ethanol, chloroform or ethanol. With pure fragrant mint aroma, with spicy and cool, strong channeling. A large number of colorless crystals precipitate at low temperature. Stored for a long time, the color gradient is deep, and the quality gradient is sticky. Soluble in water, and alcohol, ether, chloroform can be arbitrarily mixed
