Benefits of technology

This patented method allows us to effectively separate out specific chemical compounds like these two types of molecules (I) and impurity elements). It also makes sure we are able to dissolving them well when used alone without causing damage during processing. Additionally, this process helps improve the overall effectivity of chemotherapy drugs on cancer patients.

Problems solved by technology

This patented technical problem addressed in this patents is how efficiently produce pure gardenie plants called gardeniculum that contain these important health beneficial substances like orchard lutene glucodinoses and related flavonoids without causing any harmful environmental impact on humans during their consumption.

preparation example Construction

[0019] The preparation method of the present invention is: using fresh gardenia or gardenia powder as raw material, using 25-75% hydrophilic solvent aqueous solution of 5-15 times the dry weight (W / W) of gardenia, at 50-80°C Extract 1 to 3 times, each time for 1 to 3 hours, combine the extracts, filter, and the filtrate is under the conditions of -0.06 to -0.095MPa and 50 to 80°C, recover the solvent under reduced pressure, and concentrate in vacuum to form a gardenia extract.

[0020] The above-mentioned hydrophilic solvent can be one or more mixed solvents of methanol, ethanol, propanol, isopropanol or acetone, wherein methanol or acetone are preferred, and the hydrophilic solvent can also be a buffer solution with different pH values.

[0021] The physical and chemical parameter assay method of each preparation of the present invention is as follows:

[0022] The contents of gardenia iridoid glycosides, carotenoids and chlorogenic acid were determined by high-performance li...

Embodiment 1

[0027] Use gardenia produced in Fujian as the raw material, wash fresh gardenia with water, dry (air-dried, oven-dried or sun-dried), pulverize, and pass through a 20-30 mesh sieve to obtain gardenia powder, and put 2.9kg of gardenia powder into the extraction tank 40% methanol-acetone (1:1) aqueous solution with 10 times the dry weight (W / W) of gardenia powder, refluxed extraction at 68°C for 3 times, each time for 2 hours, combined extracts, filtered, Under the conditions of -0.06~-0.095MPa and 50~80°C, the filtrate is recovered under reduced pressure to recover the solvent, and then concentrated in vacuo to obtain the gardenia extract. After determination, the extraction rates of gardenia iridoid glycosides, carotenoids and chlorogenic acid were 93.2%, 96.3% and 93.1%, respectively.

Embodiment 2

[0029] Put 2.6 kg of gardenia powder of 20 to 30 meshes into an extraction tank, extract 2 times at 50°C with 25% aqueous methanol solution of 15 times the dry weight (W / W) of gardenia powder, each time for 3 hours, and combine The extract is filtered, and the filtrate is recovered under reduced pressure under the conditions of -0.06 to -0.095MPa and 50 to 80°C, and concentrated in a vacuum to form a gardenia extract. After determination, the extraction rates of gardenia iridoid glycosides, carotenoids and chlorogenic acid were 92.3%, 92.8% and 91.8%, respectively.
