Ultrasound-assisted extraction of five isoflavones from Iris tectorum Maxim
Sep Purif Technol 2011 Mar 24;78(1):49-54.PMID:32288612DOI:10.1016/j.seppur.2011.01.017.
This study investigated the use of ultrasound-assisted extraction (UAE) to improve the extraction efficiency of the classical solvent extraction techniques such as maceration extraction (ME) and soxhlet extraction (SE) to extract five isoflavones (tectoridin, Iristectorin B, iristectorin A, tectorigenin and iristectorigenin A) from Iris tectorum. The effects of various factors such as extraction solvent, solvent concentration, temperature, solvent to solid ratio, ultrasound power, extraction time and particle size on the yield of target components were investigated. The optimal UAE conditions found were: 70% (v/v) methanol solution, temperature 45 °C, solvent to solid ratio 15 ml/g, ultrasound power 150 W, extraction time 45 min and particle size 60-80 mesh. The results indicated that compared with ME at 18 h and SE at 6 h, UAE gave the highest extraction yields of tectoridin, Iristectorin B, iristectorin A, tectorigenin, iristectorigenin A and total isoflavones at 45 min. The results indicated that UAE was an alternative method for extracting isoflavones from I. tectorum.
Ionic liquid based ultrasonic assisted extraction of isoflavones from Iris tectorum Maxim and subsequently separation and purification by high-speed counter-current chromatography
J Chromatogr B Analyt Technol Biomed Life Sci 2011 Apr 15;879(13-14):975-80.PMID:21444254DOI:10.1016/j.jchromb.2011.03.010.
We developed an ionic liquid based ultrasonic assisted extraction (ILUAE) method for the extraction of the three isoflavones, namely tectoridin, Iristectorin B and iristectorin A from Iris tectorum Maxim of the Iridaceae family. Three kinds of 1-alkyl-3-methylimidazolium ionic liquids with different alkyl chain and anion were investigated. The results indicated that ionic liquids (ILs) showed remarkable effects on the extraction yield of isoflavones. In addition, the ILUAE, including several ultrasonic parameters, such as the concentration, extraction time and solvent to solid ratio have been optimized. Under these optimal conditions (e.g., with 30 min extraction time and the solvent to solid ratio of 30 ml/g), this approach gained the highest extraction yields of tectoridin (37.45 mg/g), Iristectorin B (2.88 mg/g) and iristectorin A (5.28 mg/g). Meanwhile, tectoridin, Iristectorin B and iristectorin A in the ILUAE extract were separated and purified successfully through the high-speed counter-current chromatography (HSCCC) with a two-phase solvent system consisting of n-butanol-water (1:1, v/v). The additional advantage of this approach is that 60.21 mg tectoridin, 4.33 mg Iristectorin B and 8.24 mg iristectorin A with more than 95.0% purities have been obtained from 400 mg ILUAE extract of I. tectorum within 5 h and one-step elution under the most optimized conditions (e.g., a flow rate of 2.0 ml/min, 900 rpm and the wavelengh of 280 nm). The obtained fractions were successfully analyzed by HPLC and identified by (1)H-NMR and (13)C-NMR.
Characterization and determination of the major constituents in Belamcandae Rhizoma by HPLC-DAD-ESI-MS(n)
J Pharm Biomed Anal 2011 Sep 10;56(2):304-14.PMID:21715119DOI:10.1016/j.jpba.2011.05.040.
Belamcandae Rhizoma, derived from the rhizome of Belamcanda chinensis (L.) DC., has been used as traditional Chinese medicine for the treatment of coughing and pharyngitis. However, there have been few studies dealing with the systematic analysis of the bioactive constituents in Belamcandae Rhizoma. In this work, high performance liquid chromatography-diode array detection-electrospray ionization multiple-stage mass spectrometry (HPLC-DAD-ESI-MS(n)) combined with liquid chromatography-time of flight-mass spectrometry (HPLC-TOF/MS) was established for profiling and characterization of multi-constituent in Belamcandae Rhizoma. The ESI-MS(n) fragmentation behaviors of the authentic references were proposed for aiding the structural identification of components in the extract. Thirty-five flavonoids, including 30 isoflavones and five xanthones, were identified or tentatively identified by comparing their retention times, UV and MS spectra with those of authentic compounds or literature data. Twelve of the identified compounds (neomangiferin, mangiferin, tectoridin, Iristectorin B, iristectorin A, iridin, tectorigenin, iristectorigenin A, irigenin, irisflorentin, irilone and dichtomitin) were determined by HPLC-DAD using a C(18) column. The results indicated that the developed analysis method could be employed as a rapid, effective technique for structural characterization of chemical constituents in herbal medicine. This work is expected to provide comprehensive information for the quality evaluation of Belamcandae Rhizoma, which would be a valuable reference for the further study and development of this herb and related medicinal products.
Identification and characterization of the chemical components of Iris tectorum Maxim. and evaluation of their nitric oxide inhibitory activity
Rapid Commun Mass Spectrom 2021 Jan 15;35(1):e8959.PMID:33001505DOI:10.1002/rcm.8959.
Rationale: Iris tectorum Maxim. is a traditional medicinal herb that is commonly used to treat inflammatory conditions. The present study investigated the fragmentation patterns of isoflavone glycosides and their qualitative analysis. In addition, lipopolysaccharide (LPS)-induced RAW264.7 macrophages were used to evaluate the anti-inflammatory properties of I. tectorum Maxim. samples collected at different time points during the year. Methods: High-performance liquid chromatography/quadrupole time-of-flight tandem mass spectrometry (HPLC/QTOF-MS/MS) and HPLC with diode-array detection were employed for qualitative and quantitative analysis. The fragmentation patterns of the isoflavones were observed in negative electrospray ionization mode with collision-induced dissociation (CID). Their anti-inflammatory activity was assessed via nitric oxide (NO) production in LPS-treated RAW264.7 macrophages. Results: A total of 15 chemical components were observed and tentatively identified using HPLC/QTOF-MS/MS. At low collision energy, the relative abundances of the aglycone radical anions Y0 - , [Y0 - H]-• , [Y0 - CH3 ]-• and [Y0 - H- CH2 ]-• were used for the structural characterization of tectoridin and tectorigenin-4'-O-β-D-glucoside. The radical ions [Y0 - CH3 ]-• and [Y0 - H - 2CH3 ]-• were also employed to differentiate between iristectorin A and Iristectorin B based upon their high-energy CID spectra. Levels of 9.02 mg/g of tectoridin and 1.04 mg/g of tectorigenin were found in samples collected in June, which exhibited 69.7% NO inhibitory activity. Conclusions: The characteristic fragmentation patterns enabled us to reliably identify isoflavone glycosides. The results of the quantitative determination and NO inhibitory activity offer insight into the optimal I. tectorum Maxim. harvesting time.
