factory etc. multi variety material and small batch production.
Advantages of Ultrafiltration Membrane Separation Equipment for
Traditional Chinese Medicine Injection:
1. Ultrafiltration membranes have high rejection rates of
macromolecular impurities, heat sources and bacteria, which can
improve drug safety.
2. Ultrafiltration membrane filtration belongs to physical
filtration without chemical reaction, and does not change the
active ingredients.
3. Ultrafiltration membrane filtration belongs to cross-flow
operation, and the membrane is not easily blocked.
4. Ultrafiltration membranes are imported from abroad with various
qualifications, long service life and safety.
5. Choose hygienic grade material, conform to GMP certification;
Typical application of ultrafiltration membrane technology in
traditional Chinese medicine:
1. Separation and Purification of Organic Acids, Glycosides,
Alkaloids, Flavonoids and Polysaccharides by Ultrafiltration
Membrane
2. Separation, Purification and Concentration of Oral Liquid,
Injection, Extract and Granule of Traditional Chinese Medicine
mber of studies and practices have proved that there are still many
problems in this process: first, the loss of effective ingredients,
in addition, the effect of impurity removal is not ideal. Tannins,
starches, resins and proteins in the extracts of traditional
Chinese medicines are not easily removed by the traditional
water-alcohol method, so the solid yield is still very high, which
not only brings inconvenience and pain to patients, but also makes
the preparations of traditional Chinese medicines easy to absorb
moisture and deteriorate, and the taste of the preparations is
poor.
Ultrafiltration Membrane Separation Technology for Traditional
Chinese Medicine Injection:
Ultrafiltration membranes can intercept proteins and macromolecule
compounds with radius ranging from 1 to 20 nm and molecular weight
ranging from 1000 to 300000. It can also intercept colloidal
particles of corresponding size. Ultrafiltration membranes with
molecular weight rejection values of 10,000-30,000 can basically
ensure the passage of active ingredients. The purpose of removing
impurities and retaining active ingredients can be achieved by
blocking impurities and pyrogens with molecular weight of tens of
thousands to millions.
Application of Ultrafiltration Membrane Separation for Traditional
Chinese Medicine Injection:
1. The pyrogen removal test of streptomycin sulfate (dihydrogen)
was carried out in a small coiled ultrafiltration device with a
molecular weight of 20,000. The results show that it is feasible to
use ultrafiltration instead of traditional activated carbon to
adsorb pyrogen in the production of streptomycin sulfate
(dihydrogen).
2. A pharmaceutical company in Xi'an used sulfonated
polyethersulfone membranes (SPES) with a molecular weight of 10,000
to remove pyrogen from Astragalus Injection by ultrafiltration and
then adsorbed by activated carbon, so that the qualified rate of
pyrogen fluctuated from the original to the current 100%.
3. Several kinds of compound Chinese herbal medicine injections
such as Salvia miltiorrhiza and Gardenia jasminoides were prepared
by ultrafiltration method in a domestic scientific research
institute. The ultrafiltration product had good clarity and no
precipitation appeared after 3 months. The contents of tannins,
proteins and starches in injection were determined by ch
Hempseed oil
The appearance and characteristics are very close to the low iodine
value of linseed oil, but slightly greenish.
The approximate fatty acid composition is: 10.1% saturated acid,
16% oleic acid, 46% linoleic acid, and 28% linolenic acid.
The acid value is 3 mg KOH/g, the iodine value is 149-167, and the
relative density is 0.925-0.933 (15/15 ° C). The freezing point is
about 16 °C.
The main ingredients are glycerides of linoleic acid, linolenic
acid and oleic acid.
Used in industries such as paints and soaps.
