抽 — hand radical 扌 + 由 yóu (phonetic)
抽 is a semantic-phonetic compound. The hand radical 扌 gives the meaning—an action done with the hand—while 由 supplies the sound (yóu → chōu). The original sense was to pull or draw out by hand, which extends to modern meanings like 'extract', 'draw (a lot)', or 'take time out'.
