Abstract:
ObjectiveTo establish a qualitative analysis method for the chemical constituents of the reference sample of Xiao Xumingtang， and to establish the fingerprint of 15 batches of Xiao Xumingtang， so as to evaluate the quality consistency among batches. MethodAccording to the key information of Xiao Xumingtang in the Key Information Table of Ancient Famous Classical Formulas（25 Formulas）， the reference sample of this formula was prepared， and it was detected by ultra performance liquid chromatography-quadrupole-time-of-flight mass spectrometry（UPLC-Q-TOF-MS/MS）. The chemical components were identified by self-constructed database， consulting relevant literature， and comparing with the reference substances， and the components were assigned by comparing with single drug samples and negative samples lacking single drug. The fingerprint of the reference sample of Xiao Xumingtang was established using high performance liquid chromatography（HPLC）， and the common peaks were assigned and identified through single drug samples and negative samples lacking single drug. ResultBased on the information of MS fragments， relevant literature， and database retrieval， a total of 64 compounds were identified and inferred from the reference sample of Xiao Xumingtang， including 31 flavonoids， 8 terpenoids， 12 triterpenoid saponins， 2 phthalides， 3 phenylpropanoids， 2 gingerols， 5 alkaloids， and 1 cyanoside. Among them， 21 were derived from Scutellariae Radix， 10 from stir-fried Glycyrrhizae Radix et Rhizoma， 9 from Ginseng Radix et Rhizoma， 8 from Paeoniae Radix Alba， 4 from Saposhnikoviae Radix， 3 from Stephaniae Tetrandrae Radix， 3 from Chuanxiong Rhizoma， 2 from Aconiti Lateralis Radix Praeparata， 2 from Zingiberis Rhizoma Recens， 1 from Ephedrae Herba， and 1 from Armeniacae Semen Amarum. The established HPLC fingerprint of the reference sample of Xiao Xumingtang had 23 common peaks， among which， peaks 1 and 2 were derived from Paeoniae Radix Alba， peaks 3 and 7 from Saposhnikoviae Radix， peaks 4， 8 and 9 from Stephaniae Tetrandrae Radix， peaks 10， 17， 18， 20 and 21 from stir-fried Glycyrrhizae Radix et Rhizoma， peaks 11-16， 19 and 22 from Scutellariae Radix， peak 5 from Chuanxiong Rhizoma， peak 23 from Zingiberis Rhizoma Recens， peak 6 was the common component of stir-fried Glycyrrhizae Radix et Rhizoma and Scutellariae Radix. A total of 10 compounds including albiflorin（peak 1）， paeoniflorin（peak 2）， cimicifugoside（peak 3）， 5-O-methylvisammioside（peak 7）， baicalin（peak 11）， sec-O-glucosylhamaudol（peak 13）， oroxylin A-7-O-β-D-glucuronide（peak 15）， wogonoside（peak 16）， glycyrrhizic acid（peak 21） and 6-gingerol（peak 23） were identified. The similarities of 15 batches of reference samples were>0.999， indicating that the reference samples had good consistency. ConclusionThrough the identification of the chemical constituents in the reference sample of Xiao Xumingtang， it is clear that the composition of the samples is mainly composed of flavonoids and triterpenoid saponins. The established fingerprint can basically reflect the overall chemical characteristics of the reference sample of Xiao Xumingtang， which can provide a basis for the quality research of its compound preparations.
