    Biologically active triterpenoids from Cephalaria ambrosioides.[Pubmed: 19152225 ]

    METHODS AND RESULTS:
    The roots of Cephalaria ambrosioides yielded a new triterpene, 6alpha-hydroxyhederagenic acid ( 1), in addition to the known triterpene hederagenic acid ( 2) and four corresponding saponins, leontoside A (or akeboside Stb) ( 3), kalopanax saponin A (or alpha-hederin) ( 4), saponin PG (or sapindoside B) ( 5), and Dipsacoside B ( 6). Their structures have been elucidated on the basis of their spectral data (MS, 1 D and 2 D NMR) and by some chemical transformations. The extract and all isolated compounds were evaluated for their antimicrobial, molluscicidal and IN VITRO cytotoxic activities.
    CONCLUSIONS:
    All compounds showed strong antimicrobial activity (MIC values 1.80 - 2.50 microg/mL), with 5 and 6 exhibiting activities comparable to those of standard antibiotics. Moreover, compounds 3 - 5 were active against all assayed cancer cell lines, whereas compounds 3 and 4 exhibited higher activities against Biomphalaria Glabrata snails, with minimum inhibitory concentrations of 5.4 and 6.2 microg/mL, respectively.
    Dipsacoside B Description
    Source: The flowerbuds of Lonicera confusa DC.
    Solvent: DMSO, Pyridine, Methanol, Ethanol, etc.
    Storage: Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).

    Wherever possible, you should prepare and use solutions on the same day.

    Research on quality standards of zhuang medicine Lonicerae dasystylae flos[Pubmed: 23724691]
    To establish quality standard of Zhuang medicine Lonicera dasystyla, and provide scientific basis for the quality control of L. dasystyla.
    METHODS AND RESULTS:
    Characteristics of materia medica, microscopic features, TLC indentification, inspection, extractum and determination of chlorogenic acid, macranthoidin B, Dipsacoside B were carried out through the experience, microscopic, physical and chemical methods, respectively. The standard of quality control was formulated thereafter. The characteristics of materia medica, microscopic features, TLC indentification were specified, the average contents of water, total ash, acid-insoluble ash, alcohol-soluble extracts, chlorogenic acid were 11.6%, 6.6%, 0.2% , 24.4%, 1.16%, respectively, the total amount of macranthoidin B and Dipsacoside B was 3.13%. Quality standard of L. dasystyla was proposed according to experimental results.
    CONCLUSIONS:
    The quality of L. dasystyla can be controlled effectively with the quality standard.
