    Biological Activity
    Description: Pterocarpadiols A-D are a kind of very rare 6a,11b-dihydroxypterocarpans, and their presence as markers may be helpful in chemotaxonomical classification.
    Pterocarpadiol B Description
    Source: The twigs and leaves of Derris robusta.
    Solvent: Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, 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.

    Pterocarpadiols A-D, Rare 6a,11b-Dihydroxypterocarpans from Derris robusta.[Pubmed: 26547577]

    METHODS AND RESULTS:
    Four hitherto unknown 6a,11b-dihydroxypterocarpans, namely pterocarpadiol A, Pterocarpadiol B, pterocarpadiol C, pterocarpadiol D (1-4), were isolated from the ethanol extract of the twigs and leaves of Derris robusta. Their structures were elucidated on the basis of extensive spectroscopic analysis.
    CONCLUSIONS:
    Pterocarpadiols A-D are a kind of very rare 6a,11b-dihydroxypterocarpans, and their presence as markers may be helpful in chemotaxonomical classification.
