Part Used : ไม่ระบุ
Activity : EFFECTS ON PHARMACOKINETIC
Solvent/Active Compound : -
Type of experiment : human
Type of animal : -
Type of study : Open trial
N(Total) :
N(Treatment) :
Sex : -
Age : -
Route : Oral administration
Dose/Conc.(herb) : 0.3 g ext./250 mL
Duration : -
Type of interaction : Pharmacokinetics
Interaction with drug : Folic acid*/Folate/Pteroylglutamic acid/Vitamin M/Folacid
Dose/Conc.(drug) : 0.4 mg
Result : Positive
Remark : At the 0.4 mg folic acid dose, green and black tea reduced the mean Cmax of serum folate by 39.2% and 38.6%, and the mean AUCo-infinity by 26.6% and 17.9%, resp.
Note : Data incomplete Subjects: healthy volunteers - The present results suggest an in vivo interaction between tea and folic acid with even low concns. of green and black tea exts. yielding decreased bioavailabilites of folic acid.

Interaction with drug : Folic acid*/Folate/Pteroylglutamic acid/Vitamin M/Folacid
Dose/Conc.(drug) : 5 mg
Result : Positive
Remark : At the 5 mg folic acid dose, the mean Cmax of serum folate was reduced by 27.4% and the mean AUCo-infinity was decreased significantly by 39.9% by the co-application of green tea.
