香蕉啶（英语：Bananadine）是一种宣称萃取自香蕉皮的虚构精神性物质。它的伪「萃取术」最早出现在1967年3月的《柏克莱芒刺报》，后来因为激进主义者威廉·鲍威尔信以为真，将步骤转载、以「Musa sapientum Bananadine」（语采香蕉的旧二名法命名，即大蕉）为名写入他的1970年著作《无政府食谱》，而闻名于世。伪香蕉啶萃取术的设计本意为探讨制造非法精神性药物的伦理问题、揪出吸食者，并质问：「如果普通香蕉含有精神性物质成分，政府会怎么做？」然而，纽约大学学者的研究指出，香蕉皮中并没有任何迷醉性的化学物质，吸食者只会感受到伪药效应。尽管如此，数十年来，学界、社会仍不断出现大量有关香蕉皮中迷幻物质的推测与学说。

Bananadine is a fictional psychoactive substance which is supposedly extracted from banana peels. A hoax recipe for its "extraction" from banana peel was originally published in the Berkeley Barb in March 1967. It became more widely known when William Powell, believing it to be true, reproduced the method in The Anarchist Cookbook in 1970 under the name "Musa sapientum Bananadine" (referring to the banana's old binomial nomenclature). The original hoax was designed to raise questions about the ethics of making psychoactive drugs illegal and prosecuting those who took them: "what if the common banana contained psychoactive properties, how would the government react?" One book of one-liner joke comics, published in 1971, contained a comic in which a teen is secretly handing bunches of bananas to a zoo gorilla at night, uttering the line "Just throw the skins back, man!"
