The invention relates to the technical field of identification of Apocynum, and in particular to a barcode prepared based on apocynum chloroplast genes and an application thereof. The DNA barcode label of the invention is designed based on the chloroplast genes of Apocynum, and can quickly distinguish and identify two varieties of Apocynum: Apocynum venetum and Apocynum pictum. Gene comparison shows that the ycf1 gene and rpoC2 gene of Apocynum venetum and Apocynum pictum are significantly different, and the specific sites are very different. The two varieties of Apocynum can be quickly distinguished by sequencing the two varieties. The method can provide a more accurate gene auxiliary tool for subsequent botanical classification of Apocynum.

The invention belongs to the technical field of traditional Chinese medicine modernization and medicine development, and particularly relates to a uric acid reducing product based on folium apocyni veneti extract and application of the uric acid reducing product. The core active component of the product is the folium apocyni veneti extract. In-vivo experiments prove that the extract can remarkably reduce the blood uric acid level and xanthine oxidase (XO) activity of a mouse with hyperuricemia. Six active ingredients entering blood are identified through in-vivo metabolism research. The direct interaction between the main active component and the target protein XO is verified from the molecular level through molecular docking, surface plasmon resonance (SPR) and isothermal titration calorimetry (ITC) technologies, and the uric acid reducing action mechanism of the compound is completely clarified. The invention provides a scientific basis and a high-quality product for developing a new uric acid-reducing drug effect of the folium apocyni veneti.
