Examples
Embodiment 1
[0019] Example 1 Extraction of Periplaneta americana Oil
[0020] The medicinal materials of Periplaneta americana are put into the hopper, the oil of Periplaneta americana is separated from the body of the worm at a temperature of 30-80° C. and a pressure of 10-50 MPa, and the oil of Periplaneta americana is collected.
Embodiment 2
[0021] Example 2 Preparation of defatted Periplaneta americana
[0022] Put the medicinal materials of Periplaneta americana into the hopper, separate the fat of Periplaneta americana from the body of the worm at a temperature of 30-80°C and a pressure of 10-50 MPa, and collect the medicinal residues to obtain the product.
[0023] Taking the oil yield of Periplaneta americana as an evaluation index, the pressure and temperature of the pressing method are investigated, and the results are as follows:
[0024]
[0025] According to the above table, it can be seen that at 30-80°C and a pressure of 10-50 MPa, the oil of Periplaneta americana can be effectively squeezed to remove the oil. Among them, the pressing conditions are preferably 40-60°C and a pressure of 20-40MPa.
[0026] The medicinal material of Periplaneta americana used in the present invention is obtained by suffocating living Periplaneta americana, removing impurities and drying.
Embodiment 3
[0027] Example 3 Preparation of defatted Periplaneta americana superfine powder
[0028] Weigh 100kg of defatted Periplaneta americana, put it in a sterilizing mixing and drying machine, add 20L of 75% ethanol, sterilize at 40-60°C for 1-2 hours, recover the ethanol, and vacuum-dry at 40-60°C until the moisture content is ≤6%. , crushed by a high-efficiency universal pulverizer at 4000-5000rpm / min, and the powder is pulverized with an ultra-micro vibrating mill at an amplitude of 5mm and a working temperature of 0-10°C for 20min to make particles of 10-50μm. The specific surface area of the superfine powder of Periplaneta americana increases, the dissolution rate and dissolution amount of the effective components increase, the curative effect is improved or the dosage of the product is reduced, the bioavailability is greatly improved, and the medicinal value is greatly improved. It can be used as a raw material drug Applied in powder, pill, tablet, suppository, granule, film...
