Source: families Tribulus terrestis briers come mature dry fruit

Origin: northern shaanxi, the loess plateau area, harvested time: 6 ~ *0 months

Character: light brown color powder

Effective ingredients: thistles saponins (soap Angle nucleoside). Main specifications: *0%, *0%, *0%, *0% UV

Efficacy: thorn briers extract thistles saponins-auxiliary fall blood pressure, fall hematic fat, fight artery congee sclerosis, consenescence and enhance the immune function.

Safety: edible products

Dosage: thistles saponins of typical dose for ******0 mg every day. Confirm choose contain at least ****5% thistles saponins extract.

Identify: (1) saponins positively reaction

(2) TCL: thistles saponins spots obvious

(3) HPLC: fingerprint and thistle extract reference substance fingerprint are identical with each other

Total saponins content: *0%, *0% (two specifications)

The content determination methods: UV

1, reagent and instrument improved amino benzaldehyde methanol HP***3 uv-vis spectrophotometer 1 cm than color dish

2 and reference substance solution precision says take reference substance (CoCl2 · 6 H2O) 0.6 g in *5 ml RongLiangPing, add water to dissolve, the capacity to moment degrees, shake well, using 1 cm of melamine in color than **5 + 2 nm place determined the absorption degrees for Acocl2 · 6 H2O.

3, the product precision says the product solution take **0 mg in *0 ml RongLiangPing, add methanol, ultrasonic oscillations *0 min, cold to room temperature to scale after dilution, filter, precision to absorb the filtrate 2 ml in *0 ml RongLiangPing, plus methanol 3 ml, improved

Amino benzaldehyde 5 ml, densely plug, shake well, water bath 2 hours, cold to room temperature, using 1 cm than color dish, in **5 + 2 nm place determined the absorption of A kind, and at the same time to be blank.

4, the calculation results content = (A sample × Wcocl2 · 6 H2O) / (Acocl2 · 6 H2O × 2 x W sample x **0%)
