菊科泽兰属多年生草本植物甜菊〔Steria rabaudiana(Bertoni)Hemsley〕,别名甜叶菊,原产南美洲的巴拉圭、巴西和阿根廷三国交界的阿曼拜山脉。很早以前,巴拉圭和阿根廷等国的土著居民已将甜菊的干叶制成各种甜茶销售于市场。但在原产地过去长期处于野生状态,未加栽培。近年来,随着甜菊的化学成份与药理研究取得突破性进展,甜菊被愈来愈多的国家重视且加以开发利用。目前种植较多的国家和地区是巴拉圭、巴西、日本、南朝鲜、东南亚各国和我国的台湾省。 我国大陆于1976年引进,目前已在浙江、福建、广东、广西、北京、上海等17个省、市、自治区引种成功且有小规模生产栽培。浙江省已种8000亩,产干叶570吨,经济效益230万元。福建1978年分别从日本和广西引入,目前闽南、闽中有小规模栽培。
Compositae is a perennial Herb of Steria rabaudiana (Bertoni) Hemsley alias Stevia, native to South America Paraguay, Brazil and Argentina at the junction of the Oman Mountains. Long ago, Aboriginal people in Paraguay and Argentina had made dried sweet leaves of sweet stevia on the market. However, in the past the origin of wild in the long run, no cultivation. In recent years, with the breakthrough of the chemical composition and pharmacology of stevia, stevia has been valued and developed by more and more countries. Currently more countries and regions are Paraguay, Brazil, Japan, South Korea, Southeast Asian countries and our country’s Taiwan Province. The mainland of China was introduced in 1976 and has been successfully introduced and cultivated in small scale in 17 provinces, cities and autonomous regions in Zhejiang, Fujian, Guangdong, Guangxi, Beijing and Shanghai. Zhejiang Province has planted 8,000 acres, 570 tons of dry leaves, economic benefits of 2.3 million yuan. Fujian Province was introduced from Japan and Guangxi respectively in 1978. Currently, there are small-scale cultivation in Minnan and Minzhong.
