人物简介
提出杜仲叶可代杜仲皮入药，促进杜仲资源综合利用
事迹
李家实教授是北京中医药大学中药学院中药鉴定学科的奠基人。针对杜仲皮采剥周期长（需生长15-20年）、易伤树势的资源瓶颈，她通过杜仲皮与叶的化学成分比较研究，论证杜仲叶与杜仲皮有效成分基本相同，提出以叶代皮使用，为杜仲资源可持续利用开辟道路。
该学术主张获国家科技进步三等奖，并深刻影响后续政策：2002年杜仲叶与杜仲一同列入可用于保健食品的物品名单，2005年版《中国药典》正式收载杜仲叶并以绿原酸为含量测定指标。北京中医药大学为其设立学术思想研究工作室以传承其学术贡献。

Profile
Proposed that Eucommia leaves could substitute for Eucommia bark in medicine, promoting comprehensive utilization of Eucommia resources
Story
Professor Li Jiashi was the founder of the Chinese materia medica authentication discipline at the School of Chinese Pharmacy, Beijing University of Chinese Medicine. Addressing the resource bottleneck of Eucommia bark—whose harvesting requires 15–20 years of tree growth and easily damages the trees—she demonstrated through comparative chemical studies of the bark and leaves that their active constituents are essentially the same, proposing the use of leaves in place of bark and opening a path for the sustainable utilization of Eucommia resources.
This academic proposition won the National Science and Technology Progress Award (Third Prize) and profoundly influenced subsequent policy: in 2002, Eucommia leaves were listed together with Eucommia bark among substances usable in health foods, and the 2005 edition of the Chinese Pharmacopoeia formally included Eucommia leaves with chlorogenic acid as the content-determination marker. Beijing University of Chinese Medicine established a research studio on her academic thought to carry forward her scholarly contributions.
Milestones
- Long engaged in teaching and research on Chinese materia medica authentication at Beijing University of Chinese Medicine (formerly Beijing College of Traditional Chinese Medicine)
- In 2017, Beijing University of Chinese Medicine established the 'Research Studio for the Academic Thought of Professors Li Jiashi and Yang Chunshu'
Key Contributions
- Co-authored with Yan Yuning 'A Preliminary Study on the Chemical Constituents of Eucommia Bark and Leaves' (Bulletin of Chinese Materia Medica, 1986, Vol. 11, No. 8)
- Explicitly proposed that Eucommia leaves could be used in place of the bark, laying the resource-evaluation foundation for the inclusion of Eucommia leaves in the Chinese Pharmacopoeia in 2005
- Related achievements won the National Science and Technology Progress Award (Third Prize) and the Science and Technology Progress Award (Second Prize) of the State Administration of Traditional Chinese Medicine
- Clarified the species problems of Clematidis Radix (Weilingxian) and introduced computer technology and molecular biology into the authentication of Chinese materia medica
