    Objective To detect the content of total flavonoids in different plant parts of five species of HERBA MOGHANIAE in different grown areas; to evaluate the qualities of different species of medicinal materials in different grown areas; and to find out new medicinal resources and medicinal plant parts.Methods The content of total flavonoids was detected at 510 nm by UV-Vis spectrophotometry.Results Rutin showed good linear relationship between 9.17 and 64.19 μg/mL; the average recovery rate was 99.63% and RSD was 1.36%(n=9).Among the different species,contents of total flavonoids in the roots of Moghania strobilifera (Linn.)Ait.and M.latifolia Benth.were lower than those of M.philippinensis (Merr.et Rolfe)Li and M.macrophylla (Willd.) O.Kuntze.Total flavonoids content in the roots of M.glutiaosa (Prain)Y.T.Wei was approximated to those in the roots of M.philippinensis (Merr.et Rolfe)Li and M.macrophylla (Willd.) O.Kuntze.Total flavonoids contents in the leaves of different species were relatively high,but those in the stems were relatively low.As for the plants in different grown areas,M.macrophylla (Willd.) O.Kuntze purchased from Chengdu City of Sichuan Province (grown in Yunnan Province) had the maximum content; M.philippinensis (Merr.et Rolfe) Li grown in Yiling District of Yichang City of Hubei Province had the maximum content.Total flavonoids contents in M.strobilifera (Linn.)Ait.in different grown areas were all relatively low.Conclusions This method was simple,rapid and accurate,and could be used for the quality control of HERBA MOGHANIAE.There were great differences in the total flavonoids contents in HERBA MOGHANIAE in different grown areas,indicating that altitude,climate,soil condition,growth years and storage years had significant impacts on the total flavonoids content in HERBA MOGHANIAE.With respect to the total flavonoids,the effective and sustainable utilization of resources,it was suggested that the leaves and stems of different species of HERBA MOGHANIAE could be used as medicines together with roots; and the stems could also be used.M.glutiaosa (Prain)Y.T.Wei could also be used as a alternative medicinal resource.

  • Detection of the Purity of Tartary Buckwheat Powder Based on Infrared Spectrum

    Xiaoyan ZHAO;Yunzhang XU;Jingxia WANG;Mei SUN;Lianxin PENG;Yuan LIU;

    Objective To establish the infrared spectrum identification system for Tartary Buckwheat Powder.Methods Edible starches including Barley,Wheat and Oat Powders were added into Tartary Buckwheat Powder according to the proportions of 5%,10%,20% and 30%,respectively.After direct tabletting of powder and tabletting of the dry products of the concentrate of water extracts,detection of infrared spectra was carried out.The characteristic fingerprint chromatogram and that of comparative analysis was carried out.Results After the direct tabletting of powder,the contour features of infrared spectra of the different cultivars of Tartary Buckwheat Powder were accurately matched,having great similarities.The absorption peaks of the infrared spectra between Tartary Buckwheat Powder and Adulterated Samples,which were adulterated with different proportions of Barley,Wheat and Oat Powders,had relatively similarities in peak shapes and peak positions.However there were significant differences in infrared absorption peak at 2 300-2 400 cm-1,such as the absorption peak of Tartary Buckwheat Powder sample was relatively low,while that of the adulterated samples was relatively high.Moreover with the increase of the adulterated proportion,the intensity of absorption peak enhanced.At the same time,it was found out that the intensities of the absorption peaks of three adulterated samples were in the order of Oat > Barley > Wheat.There were relatively similarities in peak shapes and peak positions between tabletting of the dry products of the concentrate of water extracts and the dry products of water extracts concentrate of adulterated samples in different proportions.However,there were significant differences in infrared absorption of the stretching vibration area of C=O or C=C at about 1 650 cm-1,such as Tartary Buckwheat Powder had two absorption peaks,while the adulterated sample had only one peak.Moreover with the increase of the adulterated proportion,the intensity of absorption peak enhanced.At the same time,it was found out that there were obvious differences in the absorption peaks of three adulterated samples.For example,Barley and Oat had one weak absorption peak at 2 300-2 400 cm-1,respectively; and the intensities of the absorption peaks were in the order of Oat > Barley.However,that of Wheat showed no absorption peak.Conclusions This method was simple,easy,repeatable,and could rapidly and effectively identify whether the edible starches including barley,wheat and oat powders were added into Tartary Buckwheat Powder.
