Benefits of technology

This patented technology involves extracting flavonoids from plants called HoneySiea Linn or other plant materials by means like sonification with an acoustic wave generator (USG). By doing this processing techniques, it can improve product quality while reducing waste compared to traditional processes such as liquid/liquid separation and crystalline precipitation.

Problems solved by technology

Technologies described in this patents involve studying plants called Lithariaceae (L.) which includes various parts like roots, leaves, stems, seeds, berries, fruits, rootlets, rhizomes, stem cells, etc., alongwith their bioactive properties such as immune response against harmful microorganisms, protection against diseases, prevention of cancer growth, treatment of leukemia, reduction of inflammations associated with necrocytopeniae, treatments related to hepatitis B/Epicolline Hydrullaginoide Axis (Human Microbism Agence).

Embodiment 1

[0038] In the ultrasonic extraction stage, select 100g of medicinal materials, add 1200g of absolute ethanol, ultrasonic frequency 200w, ultrasonic time 20min, and then add 600g of absolute ethanol for extraction;

[0039] In the solid phase extraction stage, the concentration of the sample solution is 1.0 mg / mL, the sample loading flow rate is 2.0 L / min, the sample preparation solvent ethanol solution is 60% ethanol solution, the eluent is 60% ethanol solution, and the elution flow rate is 1.5 L / min ;

[0040] As a result of the test, the purity of the total phenolic acids was 88.53%, and the yield was 7.35%.

Embodiment 2

[0042] In the ultrasonic extraction stage, select 100g of medicinal materials, add 1000g of absolute ethanol, ultrasonic frequency 250w, ultrasonic time 30min, and then add 500g of absolute ethanol for extraction;

[0043] In the solid phase extraction stage, the concentration of the sample solution is 1.5 mg / mL, the sample loading flow rate is 1.5 L / min, the sample preparation solvent ethanol solution is 70% ethanol solution, the eluent is 70% ethanol solution, and the elution flow rate is 1.0 L / min;

[0044] As a result of the test, the purity of the total phenolic acids was 89.63%, and the yield was 8.26%.

Embodiment 3

[0046]In the ultrasonic extraction stage, select 100g of medicinal materials, add 800g of absolute ethanol, ultrasonic frequency 300w, ultrasonic time 40min, and then add 400g of absolute ethanol for extraction;

[0047] In the solid phase extraction stage, the sample solution concentration is 2.0 mg / mL, the sample loading flow rate is 1.0 L / min, the sample preparation solvent ethanol solution is 80% ethanol solution, the eluent is 80% ethanol solution, and the elution flow rate is 1.0 L / min;

[0048] As a result of the test, the purity of the total phenolic acids was 87.03%, and the yield was 7.63%.

[0049] By analogy, multiple groups of experiments are done for comparison, and it can be found that the best process conditions are:

[0050] In the ultrasonic extraction stage, the amount of absolute ethanol added as an extraction solvent is 10 times the weight of the medicinal material, the ultrasonic power is 250w, the ultrasonic time is 30min, and the amount of absolute etha...
