Study On The Content Of Medicinal Ingredients In Strobilanthes Cusia (Nees) Ktze From Different Growing Areas In Fujian Province

In this research, we take Strobilanthes cusia(Nees)Ktze from different growing areas in Fujian province, HPLC as the detection method ,to research the content's difference of medicinal ingredients in Strobilanthes cusia(Nees)Ktze from 12 different growing areas in Fujian province, At the same time selected 3 different Strobilanthes cusia(Nees)Ktze from the above-mentioned 12 Strobilanthes cusia(Nees)Ktze.as representatives,continue to research annual trends of its medicinal ingredients'content and exogenous hormone's effect on the Strobilanthes cusia(Nees)Ktze.However, find the best plant resces and harvesting season of Strobilanthes cusia(Nees)Ktze.The results are as follows:1.There are significantly differences between the contents of medicinal ingredients in Strobilanthes cusia(Nees)Ktze that from different growing areas in Fujian province.The contents of indigo in Strobilanthes cusia(Nees)Ktze leaf and stem that from Zhangping,Longyan xinluo,Xianyou cultivated and minhou shangenyuan are higher than other growing areas's; The contents of indirubin is that from Zhangping,Putian dayang,Yongtai Qingyunshang and Longyan zijinshang are higher than other growing areas's; The contents of tryptanthrin is that from Nanjing hexi,Fuzhou Forest Park,Xianyou cultivated and Putian dayang are higher than other growing areas's; The totall contents of 3 medicinal ingredients in Strobilanthes cusia(Nees)Ktze that from Zhangping,Longyan xinluo,Xianyou cultivated and minhou shangen yuan are significantly higher than other growing areas's.2.The change trend of medicinal ingredients'contents in Strobilanthes cusia(Nees)Ktze are basically the same in a year. from May to July, the totall contents of 3 medicinal ingredients began to rise month by month, to August and September the contents achieve the highest value, from October to December the contents began to decline, from January to April , the contents's levels are basically stable. Therefore, the best Harvest time of Strobilanthes cusia(Nees)Ktze is August and September.3.The contents of indigo,indirubin and tryptanthrin in Strobilanthes cusia(Nees)Ktze leaves were significantly increased by the treatment of exogenous ABA, but the contents of indigo,indirubin and tryptanthrin were not apparently increased by the treatment of exogenous IAA.
