    Source: The herbs of Tribulus terrestris L.
    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).

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.

    Steroidal saponins from fruits of Tribulus terrestris.[Reference: WebLink]

    METHODS AND RESULTS:
    Further studies on the constituents of the fruits of Tribulus terrestris led to the isolation of six new furostanol saponins, 26-O-β-D-glucopyranosyl (25R)-furostane-2α,3β,22α,26-tetrol-3-O-β-D-glucopyranosyl (1-4)-β-D- galactopyranoside, 26-O-β-D-glucopyranosyl (25R,S)-5α-furostane- 2α,3β,22α,26-tetrol-3-O-β-D-galactopyranosyl(1-2)-β-D-glucopyranosyl(1- 4)-β-D-galactopyranoside, 26-O-β-D-glucopyranosyl (25R,S)-5α-furostane- 3β,22α,26-triol-3-O-β-D-galactopyranosyl(1-2)-β-D-glucopyranosyl(1-4)- β-D-galactopyranoside, 26-O-β-D-glucopyranosyl (25R,S)-5α-furostan-12- one-3β,22α,26-triol-3-O-β-D-galactopyranosyl(1-2)-β-D-glucopyranosyl(1- 4)-β-D-galactopyranoside, 26-O-β-D-glucopyranosyl (25R,S)-furost-5-ene- 3β,22α,26-triol-3-O-β-D-galactopyranosyl(1-2)-β-D-glucopyranosyl(1-4)- β-D-galactopyranoside, 26-O-β-D-glucopyranosyl (25R)-5α-furost-20(22)-en- 12-one-3β,26-diol-3-O-β-D-galactopyranosyl(1-2)-β-D-glucopyranosyl(1-4)- β-D-galactopyranoside, named terrestrosin F, terrestrosin G, terrestrosin H, terrestrosin I, terrestrosin J, Terrestrosin K, respectively.
    CONCLUSIONS:
    The structures were elucidated on the basis of spectroscopic studies of the isolated compounds and their hydrolysed products.
