Objective To comprehensively evaluate the quality of Shenmai Granules (參麥顆粒, SG) from different manufacturers by using UPLC-MS/MS method to determine the multi-indicator components of Maidong (Ophiopogonis Radix) combined with partial least squares discriminant analysis (PLS-DA) and entropy weight (EW)-TOPSIS mothod. Methods The UPLC-MS/MS method was used to simultaneously determine the contents of 12 Ophiopogon japonicus components, including ophiogenin-3-O-α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranoside, borneol 7-O-[β-D-apiofuranosyl-(1→6)]-β-D-glucopyranoside, ophiopojaponin C, ophiopojaponin D, liriope muscari baily saponins C, liriopesides B, methylophiopogonone A, methylophiopogonone B, methylophiopogonanone A, methylophiopogonanone B, ophiopogonanone A and p-coumaric acid in 85 batches of SG from three manufacturers. A comprehensive quality evaluation method for the Ophiopogon japonicus in SG was established using PLS-DA and EW-TOPSIS. Results The 12 components showed good linear relationships in their own ranges. The average recovery were 95.3%—105.3%, the RSDs were all less than 2.9%, and the precision, repeatability, and stability tests met the analytical requirements. The samples showed significant differences, methylophiopogonanone B, ophiopojaponin D, methylophiopogonone B, methylophiopogonanone A, methylophiopogonone A, ophiogenin 3-O-α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranoside and ophiopojaponin C were the main potential markers affecting the quality. The EW-TOPSIS method can be used to evaluate the quality of O. japonicus used in different manufacturers’ SG. Conclusion The established multi-index ingredients quantitative determination method is convenience and accuracy, and the combination of PLS-DA and EW-TOPSIS method can be used for the comprehensive evaluation of the quality of Ophiopogonis Radix for feeding in SG.
