Cryptomeridiol 11-rhamnoside 98% Purity CAS 349112-30-7 Sesquiterpene Glycoside for Natural Product Research Reagent Grade

• • Product Overview

    Cryptomeridiol 11-rhamnoside is a naturally occurring sesquiterpene glycoside compound isolated from the branches of Eucalyptus globulus Labill. It belongs to the class of sesquiterpenoids (specifically eudesmane-type sesquiterpenes) and consists of the aglycone cryptomeridiol linked to an L-rhamnose sugar moiety at the 11-position. This product is a high-purity research-grade reagent with a purity of ≥98% as determined by HPLC analysis, supplied as a powder.

    Natural Source

    Cryptomeridiol 11-rhamnoside was first identified as a component of the branches of Eucalyptus globulus Labill (Tasmanian blue gum). It has also been detected in the exocarp (outer skin) of apples (Malus domestica). This distribution suggests it may play a role in plant secondary metabolism and defense.

    Extraction and Purification Process

    The production of high-purity Cryptomeridiol 11-rhamnoside follows a specialized isolation protocol:

    1. Source Material Collection: Branches of Eucalyptus globulus Labill are collected and dried.

    2. Solvent Extraction: The dried plant material is ground to a powder and subjected to exhaustive extraction using organic solvents such as ethanol or methanol.

    3. Chromatographic Separation: The crude extract is subjected to multiple rounds of column chromatography, often using silica gel or preparative HPLC, to effectively separate Cryptomeridiol 11-rhamnoside from other sesquiterpenoids.

    4. Recrystallization: The partially purified compound is further purified through recrystallization to achieve the final high-purity product.

    5. Drying: The purified crystals are dried under vacuum to obtain the final powder form.
