Malaysian traditional herbs with CYP1A2 enzymes. CYP1A2 is one of the major
member of CYP and it constitute about 12-20% of the total CYP content and it
mostly a hepatic enzymes. Vivid®CYP450 Screening Kit had been use to study the
inhibition activity of Malaysian traditional herbs. α-naphthoflavone is use as positive
control that showed 100% inhibition and solvents control which is DMSO showed
0% inhibition or no inhibition. Result showed 27 herb which are Biji kedaung,
Bunga mukmin, Cabai pintal, Getah katira, Halba, Kadukai besar, Kadukai kecil,
Kacip Fatimah, Kayu angin, Kayu lilit, Ketumbar, Kulit kayu manis, Lada pahit,
