Liquid chromatography-mass spectrometry analysis of macranthoidin B, Macranthoidin A, dipsacoside B, and macranthoside B in rat plasma for the pharmacokinetic investigation
J Chromatogr B Analyt Technol Biomed Life Sci 2009 Jan 15;877(3):159-65.PMID:19097951DOI:10.1016/j.jchromb.2008.11.043.
A liquid chromatography-electrospray ionization-mass spectrometry method has been developed and validated for identification and quantification of four major bioactive saponins in rat plasma after oral administration of extraction of saponins from Flos Lonicerae, i.e., macranthoidin B, Macranthoidin A, dipsacoside B, and macranthoside B. Plasma samples were extracted with solid-phase extraction, separated on a Shim-pack CLC-ODS column and detected by MS in negative selective ion monitoring mode. Calibration curves offered linear ranges of two orders of magnitude with r(2)>0.999. The method showed the low limit quantification of 7.72, 6.06, 7.16, and 1.43 ng/mL for macranthoidin B, Macranthoidin A, dipsacoside B, and macranthoside B, respectively. The inter- and intra-CV precision (R.S.D.) were all within 10% and accuracy (% bias) ranged from -10 to 10%. The overall recovery was more than 70%. This developed method was subsequently successfully applied to pharmacokinetic profiles of the four saponins in rats. After oral administration of extraction of saponins in rats, the concentration-time course was found to be the double peaks of curve.
Quality evaluation of Flos lonicerae through a simultaneous determination of seven saponins by HPLC with ELSD
J Chromatogr A 2005 Apr 8;1070(1-2):43-8.PMID:15861786DOI:10.1016/j.chroma.2005.02.031.
A new HPLC coupled with evaporative light scattering detection (ELSD) method has been developed for the simultaneous quantitative determination of seven major saponins, namely macranthoidin B (1), Macranthoidin A (2), dipsacoside B (3), hederagenin-28-O-beta-D-glucopyranosyl(6-->1)-O-beta-D-glucopyranosyl ester (4), macranthoside B (5), macranthoside A (6), and hederagenin-3-O-alpha-L-arabinopyranosyl(2-->1)-O-alpha-L-rhamnopyranoside (7) in Flos Lonicerae, a commonly used traditional Chinese medicine (TCM) herb. Simultaneous separation of these seven saponins was achieved on a C18 analytical column. The mobile phase consisted of (A) acetonitrile-acetic acid (95:0.5) and (B) 0.5% aqueous acetic acid using a gradient elution of 29%A at 0-10 min, 29-46%A at 10-25 min and 46%A at 25-30 min. The drift tube temperature of ELSD was set at 106 degrees C, and with the nitrogen flow-rate of 2.6 l/min. All calibration curves showed good linear regression (r2>0.9922) within test ranges. This method showed good reproducibility for the quantification of these seven saponins in Flos Lonicerae with intra- and inter-day variations of less than 3.0% and 6.0%, respectively. The validated method was successfully applied to quantify seven saponins in five sources of Flos Lonicerae, which provides a new basis of overall assessment on quality of Flos Lonicerae.
Rapid semi-quantitative analysis of hemolytic triterpenoid saponins in Lonicerae Flos crude drugs and preparations by paper spray mass spectrometry
Talanta 2022 Mar 1;239:123148.PMID:34923253DOI:10.1016/j.talanta.2021.123148.
Hemolytic triterpenoid saponins, as one of the index components of Lonicerae Flos (LF), are also the main components causing hemolytic risk of LF. In order to evaluate the quality and hemolytic risk of LF crude drugs and preparations, it was a key to establish a method for quantitative analysis of hemolytic triterpenoid saponins in LF. Here, a rapid method for quantitative determining hemolytic triterpenoid saponins had been developed via paper spray mass spectrometry (PS-MS), taking macranthoidin B (MaB), Macranthoidin A (MaA) and dipsacoside B (DiB) as three target model compounds, and asperosaponin VI (ASA VI, a structural analogue) was used as internal standard. The sample solution was directly loaded and separated on chromatographic paper, sprayed and ionized by a high positive voltage, and ultimately analyzed by mass spectrometry. All analytes were detected with good linearity, precision, repeatability and accuracy. Compared with traditional high performance liquid chromatography with diode array detection (HPLC-DAD) method, PS-MS method had no significant difference in the semi-quantitative analysis of the actual samples, adding the advantages of shorter analysis time, lower reagent consumption and no-need chromatography separation process. This work provides a new strategy for fast determining hemolytic triterpenoid saponins in LF crude drugs and preparations.
Simultaneous determination of five triterpenoid saponins in different parts of Lonicera macranthoides by RRLC-MS/MS method
Pharmazie 2016 Jun;71(6):306-10.PMID:27455548doi
A rapid resolution liquid chromatography-tandem mass spectrometry (RRLC-MS/MS) method was developed and validated for the determination of five major saponins (macranthoidin B, Macranthoidin A, dipsacoside B, akebiasaponin D, and dipsacoside A) in the flower bud, stem, and leaf parts of Lonicera macranthoides. Chromatographic separation was performed on a ZORBAX SB-C18 column (2.1 x 50 mm, 1.8 μm). Acetonitrile and 0.1% aqueous formic acid were adopted as mobile phase. Detection was carried out on a triple quadrupole mass spectrometer in the negative ion mode using an electrospray source. Multiple reaction monitoring (MRM) mode was employed. The established method showed good linearity (r2 ≥ 0.9994) for all the analytes within the test ranges and the recoveries were 95.19-103.28%. Desirable intra-day and inter-day precision as well as repeatability were obtained with relative standard deviations (RSDs) less than 5%. The method was simple, sensitive, accurate and performed well in application to the sample determination within a short analysis time of 15 min. The saponin profiles of different parts of Lonicera macranthoides were obtained based on the quantitative data, showing that the flower bud contained much higher level of saponins than the stem and leaf by several orders of magnitude, and that the quantity ratios varied remarkable between these three part. The conclusions might provide scientific evidences for the reasonable application of Lonicera macranthoides, and the proposed RRLC-MS/MS method might be useful for the quality control of this medicinal plant.
Determination and Isolation of Four Anti-tumour Saponins from Lonicera macranthoides by HPLC-ESI-QTOF/MS and HSCCC
Curr Pharm Biotechnol 2017;18(13):1106-1114.PMID:29484987DOI:10.2174/1389201019666180226145427.
Background: Lonicera macranthoides is a Chinese herb that contains a large number of bioactive spanions possessing important pharmacological activities, such as anti-tumour activity. However, detailed information about their anti-tumor activity and bioactive compounds is limited. Methods: In order to evaluate the scientific basis, the method of high-speed counter-current chromatography (HSCCC) combined with high performance liquid chromatography mass spectrometry (HPLC-ESI-QTOF/MS) has been developed to separate, purify and analyze saponins from Lonicera macranthoides. Four main saponins, Macranthoidin B (I), Macranthoidin A (II), Macranthoides B (III) and Akebia saponin D (IV) were separated by HSCCC with the solvent systems of ethyl acetate-nbutanol- water (3:2:5) and n-butanol-water-methanol-ethyl acetate (1:6:0.5:4). The purities of these four bioactive ingredients (I-IV) identified and detected by HPLC-ESI-QTOF/MS were 95.1%, 92.7%, 91.8% and 96.3%, respectively. The separated saponins were evaluated for their cytotoxic activities against six tumor cell lines (MCF-7, Hela, A549, HepG2, HT29 and Eca109). Results: Results show that compounds I-IV exhibited particular significant anti-tumor activities against human mammary adenocarcinoma MCF-7 cell with IC50 values ranging from 12.7 to 30.8 µM. Conclusion: It was demonstrated that the combinative method using HPLC-ESI-QTOF/MS and HSCCC was suitable for rapid screening and isolating saponins of Lonicera macranthoides and the isolated compounds have great potential for the development of new antitumor drugs.
