    24-Methylenecycloartan-3-ol Description
    Source: The barks of Larix kaemferi
    Biological Activity or Inhibitors: 1. 24-Methylenecycloartan-3-ol and methyl caffeate show weak activity against Staphylococcus aureus and Escherichia coli.
    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.

Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

    Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com

    After receiving: The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

    Flavonoids, norisoprenoids and other terpenes from leaves of Tapirira guianensis[Reference: WebLink]
    From hexane fraction of methanol extract of leaves of Tapirira guianensis (Anacardiaceae) were obtained lupeol, 24-Methylenecycloartan-3-ol, phytol, α-amyrin, β-amyrin, sitosterol, sitostenone, glycosyl sitosterol, as well as sitosterol esterified with palmitic and stearic acids.

    Chemical constituents from leaves of Murraya paniculata (Rutaceae)[Reference: WebLink]
    Chromatographic separation of the hexane extract and the CH2Cl2 phase from the ethanol extract from leaves of Murraya paniculata yielded one triterpenoid (24-methylene-cycloartan-3β-ol), one phenylpropanoid (methyl caffeate) and seven coumarins [isomeranzine, murranganone acetate, murrayatine, murrangatine, meranzine hydrate, phebalosine and murranganone]. All the isolated coumarins were previously obtained from M. paniculata while 24-methylene-cycloartan-3β-ol(24-Methylenecycloartan-3-ol) and methyl caffeate have been described for first time in the Murraya genus. The crude extracts, fractions and pure substances were submitted to evaluation of antimicrobial potential against Staphylococcus aureus and Escherichia coli which indicated that the coumarin meranzine hydrate showed weak activity.
