广西青蒿资源研究现状

青蒿是我国传统中药,常用于消暑、明目、止汗等,其提取物青蒿素还可有效地治疗脑型疟疾。青蒿是一年生菊花科草本喜光植物,主要分布在海拔400m以下地区。广西青蒿资源丰富,全区40余个县市均有分布,为中国青蒿生产地的主要省份;2005年广西种植青蒿约670公顷,靖西县就达340公顷,且该地的青蒿提取物青蒿素含量可达1.2%。近年来,通过对青蒿野生资源的收集、筛选、生物学特性、组织培养、繁殖及栽培技术的深入研究,为建立稳定高产的青蒿生产提供了科学依据,促进了广西青蒿产业的发展。今后在青蒿生产过程中,实行中药材生产质量管理规范,保护其生物资源多样性,并利用现代生物技术,可确保青蒿生产达到高产、优质、安全和标准化,获得更多优质的青蒿,从而满足市场对青蒿素的需求。

Research status of Artemisia annua in Guangxi

Artemisia annua is a Chinese traditional medicine and usually used for removing summer-heat,improving acuity of sight and relieving night sweat and so on,and its extraction artemisinin can effectively cure the anti-malaria.Artemisia annua is an annual chrysanthemum-type herb with heliophilous,and wildly distributes below 400 meters elevation areas in China.Artemisia annua resources are abundant and it distributes in more than 40 counties in Guangxi,so Guangxi has become a main Artemisia annua production province in China.About 670 ha Artimisia annua was planted in 2005 in this region,of which 340 ha is in Jingxi County with 1.2% artemisinin of Artimisia annua. In recent years,through the researches on collection of Artemisia annua wild resources,screening,bio-characteristics,tissue culture,propagation and cultivation techniques,scientific technologies on stable and high yielding A.annua production have been developed which have promoted the development of Artimisia annua industry in Guangxi.Carrying out the good agricultural practice,protecting the biological resource diversity and applying modern biological techniques can secure high-yield,high quality,safety and standardization in the process of Artimisia annua production,obtain more high quality Artimisia annua and meet the market need of artemisinin in the future.
