ABSTRACT
Objective To study the similarity of chemical fingerprints of different proportion of Gualoupi-Gualouzi and Fruc?tus Trichosanthis,so as to provide the theoretical basis for the reasonable proportion of Gualoupi-Gualouzi. Methods The HPLC fin?gerprints and the common patterns of 6 the proportion of the 6 kinds of compatibility(30:70,35:65,40:60,45:55,50:50 and 55:45)of Gualoupi-Gualouzi and Fructus Trichosanthis were established,and the similarity of chemical fingerprints of different compati?bility proportion of Gualoupi-Gualouzi and Fructus Trichosanthis between their common patterns were compared. Results Compared with the common pattern of Fructus Trichosanthis,the similarities of the common patterns of chemical fingerprints of the above 6 kinds of compatibility proportion of Gualoupi-Gualouzi were 0.8808 ± 0.0407,0.8930 ± 0.0236,0.8995 ± 0.0195,0.9033 ± 0.0190,0.9363 ± 0.0082 and 0.8904 ± 0.0144,respectively. Among them,Gualoupi-Gualouzi ratio of 50:50 had the highest similarity,and compared with other groups,the differences were statistically significant(P<0.05 or 0.01). Conclusion The optimum proportion of Gualoupi-Gualouzi can be determined by the fingerprint technology,which provides the theoretical basis for the reasonable proportion of Gualou?pi-Gualouzi.

Methods The HPLC fingerprints and the common patterns of 6 the proportion of the 6 kinds of compatibility (30∶70, 35∶65, 40∶60, 45∶55, 50∶50 and 55∶ 45) of Gualoupi-Gualouzi and Fructus Trichosanthis were established, and the similarity of chemical fingerprints of different compatibility proportion of Gualoupi-Gualouzi and Fructus Trichosanthis between their common patterns were compared. Results Compared with the common pattern of Fructus Trichosanthis, the similarities of the common patterns of chemical fingerprints of the above 6 kinds of compatibility proportion of Gualoupi-Gualouzi were 0.8808±0.0407, 0.8930±0.0236, 0.8995±0.0195, 0.9033±0.0190, 0.9363± 0.0082 and 0.8904±0.0144, respectively.
