Problems solved by technology

The main component of the volatile oil in Atractylodes macrocephala is Atractylodes ketone. Research shows that Atractylodes atractylodes has no anti-Parkinson effect. It can be partially converted into Atractylodes lactone under light conditions, but it takes a long time and is easy to volatilize

Abstract

The invention discloses atractylenolide extract having antiparkinsonian effect, a preparation method and application thereof. Weight percentages of atractylenolide I, atractylenolide II and atractylenolide III in the atractylenolide extract are larger than 5%, 10% and 20% respectively, and purity of total lactone is larger than 35%. The application refers to that the atractylenolide extract is used to prepare antiparkinsonian drug. The preparation method includes that oxidant is added into white atractylode rhizome powder, and atractylone in white atractylode rhizome volatile oil is oxidized into atractylenolide compounds, so that content of atractylenolide is increased; zinc particles are added into an extraction solution to protect generated compounds such as atractylenolide from being further oxidized and degraded. The preparation method is simple, convenient and practical, easy to operate and more suitable for industrial production, and has remarkable progressiveness and practical value.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine, in particular to an extract of atractylodes lactone with anti-parkinson effect, a preparation method and application. Background technique [0002] Parkinson's disease (PD) is a central nervous system degenerative disease characterized by progressive death of dopaminergic neurons in the substantia nigra of the midbrain. At present, the main treatment method is western medicine, but it only improves the symptoms, but cannot control its progress, and the curative effect is weakened and the toxicity increases after long-term application. And Chinese medicine treatment has advantages such as little toxic and side effects, strong synergistic effect and more development prospects. [0003] Atractylodes macrophylla Atractylodes macrocephala The dried rhizome of Koidz. has the effects of invigorating the spleen and replenishing qi, drying dampness and diuresis, antiperspirant, and ...
