Coca is any of the four cultivated plants in the family Erythroxylaceae, native to western South America. Coca is known worldwide for its psychoactive alkaloid, cocaine. The plant is grown as a cash crop in the Argentine Northwest, Bolivia, Alto Rio Negro Territory in Brazil, Colombia, Venezuela, Ecuador, and Peru, even in areas where its cultivation is unlawful. There are some reports that the plant is being cultivated in the south of Mexico, by using seeds imported from South America, as an alternative to smuggling its recreational product cocaine.It also plays a role in many traditional Amazonian and Andean cultures as well as the Sierra Nevada de Santa Marta in northern Colombia.

  • Coca is any of the four cultivated plants in the family Erythroxylaceae, native to western South America. Coca is known worldwide for its psychoactive alkaloid, cocaine. The plant is grown as a cash crop in the Argentine Northwest, Bolivia, Alto Rio Negro Territory in Brazil, Colombia, Venezuela, Ecuador, and Peru, even in areas where its cultivation is unlawful. There are some reports that the plant is being cultivated in the south of Mexico, by using seeds imported from South America, as an alternative to smuggling its recreational product cocaine.It also plays a role in many traditional Amazonian and Andean cultures as well as the Sierra Nevada de Santa Marta in northern Colombia. The cocaine alkaloid content of dry Erythroxylum coca var. coca leaves was measured ranging from 0.23% to 0.96%. Coca-Cola used coca leaf extract in its products from 1885 until about 1903, and started using decocainized leaf extract ever since. Extraction of cocaine from coca requires several solvents and a chemical process known as an acid-base extraction, which can fairly easily extract the alkaloids from the plant. (en)
  • Koka adalah sebuah tanaman dalam famili Erythroxylaceae, tumbuhan asli di baratlaut Amerika Selatan. Tanaman ini memainkan peran penting dalam budaya Andes tradisional. Daun coca berisi alkaloid kokain, dasar bagi obat kokain, yang merupakan stimulan kuat. Koka tidak sama dengan cocoa yang juga di Amerika Selatan di mana dari itu cokelat dibuat. Tanaman ini berbentuk semak duri hitam, dan tumbuh hingga mencapai tinggi 2–3 m (7–10 kaki). Cabangnya lurus, dan daunnya, berwarna hijau, tipis, gelap, oval, dan runcing di ujungnya. Daunnya juga memiliki karakteristik khusus yaitu dikelilingi dua garis melengkung membujur, satu garis di sisi lain daun, dan yang paling jelas di bawah daun. Bunganya kecil, dan tersusun dalam kumpulan kecil di tangkai yang pendek; mahkotanya terdiri dari lima daun bunga kuning putih, kepala putik berbentuk hati, dan putiknya terdiri dari tiga karpel yang bersatu membentuk tiga ovarium. Bunganya berubah menjadi beri merah. Daunnya kadang-kadang dimakan oleh larva ulat bulu Eloria noyesi. Bila dikunyah seperti mengunyah sirih, lama kelamaan menimbulkan sensasi segar. (in)
  • 古柯(英語:coca),在古柯科古柯屬下四種植物的通稱,原產於南美洲。在阿根廷,秘魯,玻利維亞,烏拉圭,哥倫比亞等國家中,這是重要的經濟作物,也是一種傳統藥草,在印加帝國文化中佔有重要地位。古柯葉子中富含生物鹼成份,其中包含咖啡因與古柯鹼等。因為它是製作古柯鹼的主要原料,因此其種植常是非法的。 古柯葉子中的古柯鹼含量,只有0.25%至0.77%之間,含量很低。要經過數道提煉程序後,才能被純化,製成古柯鹼。一般嚼食古柯葉,或是飲用古柯茶,不會出現毒性反應,或造成生理上的問題。從1885年開始,可口可樂的配方中,就包含了古柯葉的抽取物。在大約1929年前後,可口可樂在加入古柯葉添加物之前,會先移除其中的古柯鹼成份。 (zh)
