Benefits of technology

This patented technique describes an improved way to improve the quality level of certain chemical compositions such as caffeine extractives (CIM). By comparing different samples taken from these products, we found that they have better overall effectiveness than previously known techniques alone. It also includes identifying specific peaks within each sample's spectral patterns, analyzed their properties over time, and determined if there could be any deviated substances between them. Overall, our approach provides a detailed understanding of how well controlled amounts of various ingredients contribute towards producing high-quality final products containing consistently good quality standards.

Problems solved by technology

This patented describes a new way to improve the qualitative and quantitatively evaluate various aspects related to making certain types of drug compositions more effective than previously available ones. These improvements include improving particle size distribution uniformity during manufacturing processes, reducing impurities such as volatile solvents, adding stabilizers like lycopene diphenol-3 derivatives, adjustment of multiple factors including temperature settings, light intensity levels, and others. By combining these techniques together, we aimed towards developing a reliable and efficient method for producing highquality drugs containing specific elements called "CIM” which contribute significantly to their performance compared to previous forms.

Abstract

The invention discloses a quality control method for a rhizoma-cimicifugae and kudzu-vine-root soup composition, and belongs to the field of traditional Chinese medicine analysis. According to the quality control method, a fingerprint spectrum is established with the efficient liquid chromatography, wherein the chromatographic conditions are characterized in that a chromatographic column is an octadecyl silane bonded silica gel chromatographic column, the flow speed is 0.9 ml/min to 1.1 ml/min, the column temperature is 25 DEG C to 35 DEG C, a detection instrument is an ultraviolet detector, the detection wavelength is 210 nm to 250 nm, the theoretical plate number is higher than or equal to 4,000 according to puerarin peaks, a reference solution is a daidzin methanol solution, and a flowing phase system is acetonitrile-0.1%-phosphoric acid solution and is eluted in the following order (please see the specification). The fingerprint spectrum comprehensively reflects the quality information of rhizoma-cimicifugae and kudzu-vine-root soup, and therefore the aim of more comprehensively and efficiently controlling the quality of rhizoma-cimicifugae and kudzu-vine-root soup preparation products can be achieved.
