2、 Chemical constituents of Aconitum kusnezoffii leaves

Aconitum kusnezoffii leaves contain alkaloids, the main components of which areAconitineIt also contains phenolic components, sugars and polysaccharides.

3、 Pharmacological effects of Aconitum kusnezoffii leaves.The study of the pharmacological effects of Aconitum kusnezoffii leaves on the rats in the experiment group of the Second Affiliated Hospital of the people's Republic of China in the period of 1-2

1. anti inflammatory effect     ; 0.05% total alkaloid of Aconitum kusnezoffii leaves has a very significant anti-inflammatory effect at the 4th hour, and the swelling elimination rate can reach about 3.5%. In the experiment, it was also found that the preparation of Aconitum kusnezoffii leaves can increase the appetite, health and vitality, and weight gain of rats. Among them, the total alkaloids of Aconitum kusnezoffii leaves were the most significant.

2. analgesic effect 2.5% Aconitum kusnezoffii leaf decoction has a quite significant inhibitory effect on acetic acid-induced "writhing movement" in mice. The total alkaloids of Aconitum kusnezoffii leaves at 2.5mg/kg also produced almost the same effect.

3. 20% and 50% toxic Decoction of Aconitum kusnezoffii leaves were given to mice by gavage, and the maximum dose of Aconitum kusnezoffii was up to 15mg / kg. No toxic reaction was found, which could increase the appetite and weight of animals. The LD50 of total alkaloids of Aconitum kusnezoffii leaves in mice was 15mg / kg by gavage.
