N(Total) : -
N(Treatment) : -
Sex : -
Age : -
Route : -
Dose/Conc.(herb) : ginkgolide A 1.1 mcg/mL
Duration : MCF-10A cells were treated with ginkgolide A for 24 h
Type of interaction : Pharmacokinetics

Dose/Conc.(drug) : -
Result : Negative
Remark : Result: None of the terpene trilactones increased CYP1B1 or CYP1A1 mRNA expression. These compounds also and had no effect on AhR dependent report activity.
Note : Solvent/compound: Ginkgo biloba extract contained 6.2% w/w terpene trilactones, consisting of bilobalide (2.8%), ginkgolide A (1.1%), ginkgolide B (0.3%), ginkgolide C (1.4%), and ginkgolide J (0.6%). It also contained 21% w/w flavonols (as sum of the aglycone and glycosides), consisting of quercetin (10.6%), kaempferol (6.3%), and isorhamnetin (4.1%).
