ABSTRACT
In this study， quantitative analysis of multi-components with single marker(QAMS) was established and validated to simultaneously determine four sesquiterpenoids(β-eudesmol， atractylon， atractylolideⅠ， atractylolide Ⅱ) in Atractylodis Rhizome based on the gas chromatographic method(GC). Using β-eudesmol as the contrast， the relative correctionfactors(RCF) of the other three sesquiterpenoids were determined by GC. Within the line arranges，the values of RCF of β-eudesmol to atractylon， atractylolideⅠand atractylolide Ⅱ were 0.823， 0.690 and 0.766， respectively. The RCF had a good reproducibility in various instruments， chromatographic columns. According to their RCF， we simultaneously determined four sesquiterpenoids in Atractylodis Rhizome only using one marker. The results of QAMS method were validated by comparing with that of internal standard method， and no obvious significant difference was found.

The present study is establish the quantitative analysis of multi-component with single marker for determining three anthroic acids, (25S)-antcin K, (25R)-antcin K and (25S)-antcin C in the petri dish cultured Antrodia camphorata. The relative correction factors of (25S)-antcin K and (25R)-antcin K were established by high performance liquid chromatography with (25S)-antcin C as the internal reference. Relative correction factors were used to calculate the contents of (25S)-antcin K and (25R)-antcin K which were difficult to gain in abundance. At the same time, the contents of these three compounds were determined by external standard method. Two methods were compared to evaluate the accuracy and rationality of the multi-components with single marker method in the determination of the petri dish cultured A. camphorate. It was found that the quantitative method of multi-component with single marker and external standard method showed no significant difference. In summary, taking (25S)-antcin C as the internal reference, the method of multi-component with single marker can be applied to the quantitative analysis of (25S)-antcin K and (25R)-antcin K in the petri dish cultured A. camphorata.

Objective To establish a quantitative analysis of multi-components with single marker (QAMS) for the simultaneous determination of chlorogenic acid, cryptochlorogenin acid, caffeic acid, hyperoside, isoquercitrin, astragalin, kaempferol in crude and processed Cuscuta australis, which is proved to be a scientific and feasible method in the quality analysis in C. australis. Methods Six relative correction factors (RCFs) of chlorogenic acid, cryptochlorogenin acid, caffeic acid, isoquercitrin, astragalin, kaempferol was established in the HPLC method with the hyperoside as the internal standard (IS), which was to calculate the mass fraction of each. The mass fraction of seven effective constituents in crude and processed C. australis was calculated by the external standard method (ESM) at the same time. Compared with the content results determined by the ESM and QAMS, the feasibility and accuracy of QAMS method were verified. Results The relative correction factor (RCF) was perfect. The detection calculated by QAMS was consistent with the results by ESM. Conclusion The method with a single marker, using the hyperoside as IS, is accurate and feasible for the quantitative analysis of six other effective constituents in C. australis.
ABSTRACT
This study is to determine five naphthaquinones (acetylshikonin, β-acetoxyisovalerylalkannin, isobutylshikonin, β,β'-dimethylacrylalkannin,α-methyl-n-butylshikonin） by quantitative analysis of multi-components with a single marker (QAMS). β,β'-Dimethylacrylalkannin was selected as the internal reference substance, and the relative correlation factors (RCFs) of acetylshikonin, β-acetoxyisovalerylalkannin, isobutylshikonin and α-methyl-n-butylshikonin were calculated. Then the ruggedness of relative correction factors was tested on different instruments and columns. Meanwhile, 16 batches of Arnebia euchroma were analyzed by external standard method (ESM) and QAMS, respectively. The peaks were identifited by LC-MS. The ruggedness of relative correction factors was good. And the analytical results calculated by ESM and QAMS showed no difference. The quantitative method established was feasible and suitable for the quality evaluation of A. euchroma.
ABSTRACT
Objective: To set up a new method - quantitative analysis of multi-components by single-marker(QAMS) to determine eight components - notoginsenoside R1, ginsenoside Rg1, Re, Rb1 and Rd, harpagoside, cryptotanshinone and tanshinone I in Fufang Xueshuantong(FX) capsule simultaneously, and validate its accuracy and feasibility for application in preparation. Methods: FX capsule was used as the research object, notoginsenoside R1 was selected as marker under 203 nm to evaluate the quality of ginsenoside Rg1, Re and Rb1, Rd, and cryptotanshinone as marker under 270 nm to evaluate the quality of harpagoside and tanshinone I. The relative correction factors (RCF) of components were calculated. The method was validated by comparison of the quantitative results between external standard method and QAMS method. Results: No significant differences were found in the quantitative analysis of components by external standard method and QAMS method. Conclusion: It is a convenient and accurate method to determine multi-components when authentic standard substances are not available. It can be used to control the quality of FX capsule.

ABSTRACT
OBJECTIVE: To develop a quantitative analysis of multi-components by single marker (QAMS) method for simultaneous determination of four flavonoid glycosides in Mentha haplocalyx Briq. by using one reference substance. METHODS: Four main effective components (hesperidin, diosmin, didymin, and buddleoside) were selected as analytes to evaluate the quality of Mentha haplocalyx Briq.. With hesperidin as internal reference standard, the relative correction factors (RCF) of the other three components to hesperidin were calculated within certain ranges. The contents of hesperidin in the samples of Mentha haplocalyx Briq. were determined by using the external standard method, and the contents of the three other ingredients were calculated by their RCFs. The method was evaluated by comparison of the quantitative results between external standard method and QAMS method by SPSS 17.0. RESULTS: No significant differences were observed between the quantitative results of these two methods (RSD 0.05). The validated HPLC method had the advantages of precision, reproducibility, and reliability. CONCLUSION: The QAMS method we established is suitable and feasible for the quality control of Mentha haplocalyx Briq.
