[Determination of gentiopicroside in different morphological types of cultivated Gentiana manshurica population].Zhongguo Zhong Yao Za Zhi. 2004 Sep; 29(9):841-4.ZZ
OBJECTIVE
To study the correlation between morphological variation and gentiopicroside content in cultivated Gentiana manshurica roots and to investigate the feasibility of breeding new varieties of high effective constituent content.
METHOD
Gentiopicroside was determined in 5 morphological types of cultivated G. manshurica roots by HPLC, which are normal (or wild) type, white-flowered type, thick-rooted type, broad-leaved type I and broad-leaved type II.
RESULT
Among different types gentiopicroside content is the highest in the roots of thick-rooted type, the contents decrease as following order: normal type, broad-leaved type I white-flowered type and broad-leaved type II, and the gentiopicroside contents in the same type root system are a positive correlation with root ages, as 3-years-age roots > 2-years-age roots > 1-year-age varied with roots.
CONCLUSION
The contents of effective constituent vary with the morphological variation in cultivated G. manshurica. It is feasible to breed a new variety with high effective constituent with the morphological character as a selecting index.
