Question about chemical constituents of Chinese herbs

[Guest guest]

Do anyone know a source of data for a quantified analysis of the

constituents of Chinese medicinals? It is very easy to find lists

of the chemicals contained, but to track down the actual quantified

ranges of these chemicals is difficult. Clearly I just don't know

exactly where to look. I can only find lists that give the ranges

of one or two key constituents, even in Chinese.

 

I would not be surprised if the answer comes from someone savvy in

the fields of botany or chemisty. The info is not common in TCM

books and is hard to find in the Western med literature, via pubmed

or in Chinese. Anyone?

Eric,

 

The only source I know of that lists approx. concentrations (ppm) is the

following free-access website:

 

http://www.ars-grin.gov/duke/

Jim Duke's Phytochemical and Ethnobotanical Databases

(Agricultural Research Service)

 

Contains many Chinese herbs but not all common ones.

 

Most texts I've seen only list ingredients. Several people contributed

suggestions re chemical constituent texts, but I forgot to ask whether these

also contain quantitative analyses. Anyone know about the following?

 

Chinese Drugs of Plant Origin by Tang and Eisenbrand; Springer-Verlag

 

Constituents of Chinese Herbal Drugs by Hsu (encylopedic reference)

 

Chinese Materia Medica: Chemistry, Pharmacology and Applications by

You-Ping Zhu

 

Traditional s, Molecular Structures, Natural Sources and

Applications by X. Zan, J. Zhou & G. Xie, Ashgate, 1999

ISBN 0- 566-08210-1
