This research aims to determine the quantity of phenolic compounds at all lost and anti-bacterial.Free radicals present in the coffee powder grinding and coffee. When prepared in different solvent Coffee powder samples by grinding and coffee from the coffee shop Le ' nice branch building 26 Nakhon Ratchasima rajabhat University .. .. Tumbol Amphoe mueang Nakhon Ratchasima province From the study of phenolic compounds at the quantity lost by using. Folin.-.Ciocalteu's reagent .. found in layers of powdered extract, acetic ethyl's coffee grind and coffee.Phenolic compounds are lost at the highest total (506.078 ± 519.571 ± 20.86 and 11.16 mg of acid galley fixture kilograms) and has a value that is not significantly different at the 0.05 level. the sensitivity study for DPPH antioxidant IC50 values was found to be of the best extraction of acetic ethyl's floor two examples show the highest antioxidant vitamin c (± 0.0002 ± 0.0094 mg/ml and 0.0048 0.0108) Study on effect of antioxidants by FRAP method was found to be best extracted in ethyl-acetic quantity has highest antioxidant (668.602 ± 631.542 ± 18.92 and 17.33 mg of iron per kilogram of weight, for example). From this research indicates that ethyl acetic te is the appropriate solvent to bring bite antioxidants from coffee powder grinding and molasses, coffee, which shows the results of analysis demonstrate the value and quantity of phenolic compounds, all lost. Antioxidant vitamin c with the DPPH method and how a relatively good FRAP.

The research aims to determine the amount of total phenolic compounds. And anti
-oxidants are in ground coffee and coffee grounds when prepared in different solvents. For example, ground coffee and coffee grounds from the coffee shop Le 'nice Branch .. 26 .. Nakhon Ratchasima Rajabhat University
in Muang district of Nakhon Ratchasima. The study phenolic compounds, all using. Folin .-. Ciocalteu's the reagent .. In the ethyl acetate extract of ground coffee. And the grounds that
the amount of phenolic compounds highest total. (506.078 ± 11.16 and 519.571 ± 20.86. Mg of acid, gallic g per kg) and a value that does not differ significantly at. 12:05. For the study, antioxidant activity DPPH showed that IC50 of the extract layer of ethyl acetate, the two samples. showing the highest antioxidant activity. (0.0094 ± 0.0002 and 0.0108 ± 0.0048. Milligrams per milliliter) study the effects of antioxidant with FRAP found that the extract in ethyl acetate has the highest amount of antioxidants. (668.602 ± 18.92 and 631.542 ± 17.33. Milligrams of iron per kilogram of body weight) from this study indicate that. Ethyl acetate is the most suitable solvent to extract the antioxidants from ground coffee and coffee grounds, which shows the results of the analysis reflect the total phenolic compounds. The antioxidant activity by DPPH and FRAP methods are quite good.

The purpose of this research is to find all the phenolic compound and antioxidant
.Free radicals in the coffee powder and ground coffee residue when prepared in different solvents By example of coffee powder grinder and coffee residue is derived from the coffee shop Le 'nice branch building. 26... Of Nakhon Ratchasima Rajabhat University
.Canton City District, Nakhon Ratchasima province. The phenolic compound using Folin.-.Ciocalteu 's reagent... Found in the ethyl acetate extract powder, exceed the grind coffee and coffee residue is
.A phenolic compound all highest (506.078 vector and vector 11.16 519.571 20.86 mg of acid Gaelic per kilogram). And the different level of 0.05.The antioxidant activity DPPH found that the value of the extracts IC50 I ethyl acetate of two examples show the highest antioxidant (0.0094 vector and vector 0.0002 0.0108 0.0048 mg / ml). The effects of antioxidants FRAP method showed that the ethyl acetate extracts in a ปริมาณสารต้านอนุมูลอิสระ highest (668.602 edge 18.92. 631.542 17 and convert.33 mg of iron per kilogram of weight, for example). From this research we found that Ethyl acetate as solvent the most appropriate to bite of antioxidants from ground coffee powder and coffee grounds.Antioxidant activity DPPH way and how FRAP quite good!
