Stable Levocarnitine compound and pharmaceutical composition thereof |
| abstract |
The invention relates to a stable Levocarnitine compound and a pharmaceutical composition thereof. The compound is prepared by carrying out recrystallization 1-3 times on a crude product of Levocarnitine with a solvent which comprises ethyl acetate and methanol and has the ratio of ethyl acetate to methanol being 1 to 1, and simultaneously decoloring with active carbon to obtain the white crystals, wherein, the ratio of the crude product of Levocarnitine to active carbon to the mixed solvent of ethyl acetate and methanol is 1 to 0.05 to 8. |
