The components transitive regularity of three dosage forms of Liuwei Dihuang Fufang / 数字中医药（英文）

ABSTRACT

@#Objective To explore the transitive regularity of holistic constituents from the crude slices of the medicinal raw materials (MCS) to the formula granules (FG), fufang decoction (FD), and finally, the concentrated pills (CP) of Liuwei Dihuang Fufang (六味地黄复方, LWDHF). Methods Samples for MCS, FG, FD, and CP of LWDHF were obtained, and a fingerprint database was established using high-performance liquid chromatography (HPLC), by separating the samples in an XB-C18 column and analyzing the transitive regularity of components using the total quantum statistical moment (TQSM), including total quantum zero moment (AUCT), total quantum first moment (MRTT), total quantum second moment (VRTT), and its similarity approach. The AUCT, MRTT, and VRTT were calculated based on the representative HPLC chromatograms of FG, FD, and CP of LWDHF. Results AUCT of FG, FD, and CP of LWDHF was 71 804, 46 553, and 144 646 µV·s, respectively; MRTT was 14.43, 14.54, and 18.85 min, respectively; and VRTT was 106.98, 112.84, and 269.12 min2, respectively. Comparing the similarity of FG/FD, FG/CP and FD/CP of LWDHF, the TQSM similarity values were 98.66%, 76.62%, and 75.37%, respectively, whereas the traditional similarity evaluation values were 98.68%, 85.43%, and 85.60%, respectively. Conclusion The results perform little distinction in the total composition between FG and FD, whereas some distinction existed between FD and CP. Experimental evidence, therefore indicates that FG could be used as the alternative of MCS in clinical applications.
