苦茶碱

Theacrine (also known as Teacrine) is a nootropic stimulant and a structural analog of caffeine, appearing to be synthesized from caffeine in some plants. It is a bitter, white crystalline purine alkaloid that increases activity in the brain and induces temporary improvements including enhanced alertness, wakefulness, and stimulation.[citation needed] Relative to caffeine, it displays about 2/3rds the potency in terms of the stimulation it produces.[citation needed].
