Embodiment 1

[0045] (1) Take 800g of pigeonpea leaves and 200g of sarcocarpus, crush them, add 12 times the amount of water to soak for 2 hours, extract the volatile oil by steam distillation for 4 hours, collect the volatile oil, water extract and medicinal residue for later use; dissolve the volatile oil with ethanol Finally, add 20 times the amount of volatile oil to the saturated solution made of β-CD, stir at 50°C for 3 hours, then stir at room temperature for 2 hours, let stand overnight, filter, precipitate and dry at low temperature to obtain 15g of clathrate.

[0046] (2) Extract the above dregs with 5 times the amount of water again, combine the two extracts, filter, and concentrate the filtrate under reduced pressure at 70°C to a relative density of 1.25, add ethanol to make the alcohol content 80%, and let it stand for 24 hours, filtered, and the filtrate recovered ethanol under reduced pressure, concentrated, dried, and pulverized to obtain 85 g of water extract.

Abstract

A Chinese medicine for treating the ischemic necrosis of femur head is prepared from cajan leaf, glabrous sarcandra herb and medicinal additive. Its preparing process is also disclosed.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicine pharmacy, and in particular relates to a compound pigeon pea leaf traditional Chinese medicine preparation and a preparation method thereof.
