Angelol H 98% Purity Research Grade Coumarin Compound CAS 83247-73-8 for Natural Product Reference Standard

• • Product Overview

    Angelol H is a naturally occurring coumarin compound isolated from Angelica pubescens and related species. It is one of the angelol-type coumarins, characterized by a pyranocoumarin skeleton with specific hydroxylation and prenylation patterns. This compound contributes to the bioactive profile of Angelica plants and is used as a reference standard in natural product research.

    Chemically, angelol H is a coumarin derivative with the molecular formula C₂₀H₂₄O₆ and a molecular weight of 360.40 g/mol. It appears as a white to off-white crystalline powder, soluble in methanol, ethanol, and chloroform. The compound is supplied at ≥98% purity as determined by HPLC analysis.

    Synthetic Process:

    This compound is obtained through isolation from natural plant sources:

    Extraction: Angelica pubescens root is extracted with methanol or ethanol. The extract is concentrated and subjected to liquid-liquid partitioning.

    Purification: The coumarin-enriched fraction is purified by silica gel column chromatography using petroleum ether-ethyl acetate gradient elution, followed by recrystallization to obtain pure angelol H.

    This product is a high-purity analytical reference standard intended for natural product research.
