Targets: |
Aldose reductase |
In vitro: |
Journal of the Korean Society for Applied Biological Chemistry, 2015, 58(3):365-371. | Plant-derived molecules from Saussurea grandifolia as inhibitors of aldose reductase.[Reference: WebLink] | Saussurea grandifolia was tested for aldose reductase (AR) inhibition as part of a search for potentially therapeutic natural compounds. METHODS AND RESULTS: Stepwise polarity fractions were tested for in vitro inhibition of rat lens AR. Of these, the ethyl acetate (EtOAc) and n-butanol (n-BuOH) fractions exhibited AR inhibitory activities. A chromatographic separation of the active EtOAc and n-BuOH fractions led to the isolation of nine compounds, which were known and identified as vitexin (1), genkwanin-5-O-glucoside (2), vitexin 2″-p-hydroxybenzoate (3), kaempferol-3-O-rutinoside (4), isovitexin (5), quercitrin (6), isoquercitrin (7), 1,5-di-O-caffeoylquinic acid (8), and Vicenin -1 (9). Among these compounds, compounds 6, 7, and 8 showed very strong inhibitory activities against AR (IC50’s = 0.34, 0.32, and 0.08 μM, respectively).
CONCLUSIONS:
The results suggest that S. grandifolia is clearly a potential source for therapeutic agent that might be useful for the treatment of diabetic complications. |

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. |

Regulatory Toxicology and Pharmacology, 2016:S0273230016303026. | Acute and repeated doses (28 days) oral toxicity study of Vicenin-1, a flavonoid glycoside isolated from fenugreek seeds in laboratory mice.[Reference: WebLink] | Vicenin -1 (fenugreek glycoside) has been proven to possess potent anti-inflammatory and anti-oxidant activity. The objective of the present investigation was to determine in-vivo acute and subacute (28-days repeated dose) oral toxicity of Vicenin -1 isolated from fenugreek seed.
METHODS AND RESULTS:
Vicenin-1 (93%) was isolated from a hydroalcoholic extract of fenugreek seed and characterized using HPLC, TLC, 1H NMR and 13C NMR. Acute oral toxicity (AOT) and subacute toxicity studies of Vicenin -1 were carried out according to OECD 425 (up-and-down procedure) and OCED 407 guidelines in Swiss albino mice. In AOT, Vicenin -1showed 10% mortality when administered at a dose of 5000 mg/kg. However, when vicenin-1 was administered for at doses of 37.5, 75, or 150 mg/kg 28-days it did not show any mortality at the administered doses. Vicenin -1 (75 mg/kg) did not show observational, behavioral, biochemical or histopathological toxic effects. There were minor alterations in body weight, hematology, and histopathology of mice administered with Vicenin -1
(150 mg/kg), but these changes were within normal laboratory ranges. The highest concentration of Venicin-1 was found in liver (3.46%) followed by lung (0.65%).
CONCLUSIONS:
In conclusion, Vicenin -1 showed median lethal dose (LD50) of 4837.5 mg/kg with no-observed-adverse-effect levels (NOAEL) at 75 mg/kg and lowest adverse effect levels (LOAEL) at 150 mg/kg for both sexes of mice during AOT and sub-acute toxicity study, respectively. |
