石杉科由两个属组成，石杉属和痰藻属。由于含有石杉碱甲等石松生物碱（用于治疗多种人类疾病），石杉科植物在中国正在迅速减少，这主要是由于过度采伐。为此，我们于1995 ~ 2001年对中国石杉科植物资源进行了调查。本研究的主要目的是：对中国石杉科植物资源进行编目，包括各种石杉科植物在中国的发生、一般分布和丰富度，并确定每种石杉科植物的传统用途和药用价值。通过野外调查、采集、走访当地中医、查阅标本馆标本和查阅文献资料，鉴定出石杉属植物29种、2变种、2变型和马尾杉属植物19种。对这些植物的民族植物学研究表明，其中33种被当地社区用于药用目的。蛇足石杉是其中最受欢迎的一种。因此，它正在观察最大的下降，要求改变收集做法和对这些植物的普遍态度。为了扭转这些物种数量下降的趋势，需要制定保护计划，并就这些植物的适当采集方法及其在中国的销售对当地社区进行培训。此外，发展栽培或其他繁殖方法，如体外繁殖，将带来额外的好处，即提高当地社区的社会经济水平，并使石杉碱甲的这一重要来源具有可持续性。(c)2005爱思唯尔爱尔兰有限公司保留所有权利。
The Huperziaceae is comprised of two genera, Huperzia and Phlegmarittrus. Because of the content of Lycopodium alkaloids like huperzine A, which are used to treat a number of human ailments, plants of the Huperziaceae are experiencing a rapid decline in China, mostly due to over-harvesting. Because of this trend, we engaged from 1995 to 2001 in an investigation of the natural resources of the Huperziaceae in China. The main objectives of this study were: to catalog Huperziaceae plant resources including the occurrence, general distribution, and abundance of the various Huperziaceae species in China; and to determine traditional use and pharmaceutical values of each species. Twenty-nine species, 2 varieties, and 2 forma of Huperzia and 19 species of Phlegmariurus were identified through field investigation, collection, visits with local traditional doctors, and review of specimens in herbaria and of the literature. Ethnobotanical studies of these plants revealed that 33 of these species are used by the local communities for medicinal purposes. One species, Huperzia serrata, is one of the most popular. As a result, it is observing the greatest decline, mandating a change in collection practice and general attitude towards these plants. Introduction of conservation plans and training of the local communities regarding appropriate collection practices of these plants and their marketing in China are required to reverse the trend of decline among these species. In addition, development of cultivation or other propagation practices, such as in vitro propagation, would have the added benefits of socio-economic uplift of the local communities and sustainability of this important source of huperzine A.
