为有效利用野生金荞麦资源，对贵州省毕节市内搜集的14份野生金荞麦栽种后观测其主要农艺性状，测定根茎的主要成分含量并进行相关性分析。结果表明：野生金荞麦根茎的主要成分符合《中华人民共和国药典2010版·一部》指标要求的资源有9份；表儿茶素含量与醇溶性浸出物含量、总灰分含量呈极显著正相关，与水分含量呈正相关。其中，来自威宁县双龙（Z1）、金沙县平坝绿稿坪（Z9）、织金县化起（Z11）、织金县桂果（Z13）、金沙县太平（Z14）等5份资源的根茎表儿茶素含量高于0．04％、醇溶性浸出物含量高于15．1％，可加快繁殖进行试验示范；来自赫章县雉街（Z2）、赫章县珠市（Z6）、金沙县平坝新庄（Z10）、织金县龙场（Z12）等4份资源的表儿茶素含量在0．03％～0．04％、醇溶性浸出物含量14．26％～19．26％，可根据育种需要加以利用。主要成分中对表儿茶素含量的影响顺序为醇溶性浸出物含量＞水分含量＞总灰分含量，金荞麦栽培、选育应选择表儿茶素含量和醇溶性浸出物含量均高的类型材料。

For effectively utilizing F.cymosum resources,14 wild F.cymosum resources were collected from Bijie City in Guizhou Province.The authors observed the main characters,determined the main ingredient contents in rhizome,and then analyzed the correlation coefficients between the main components in Shaojiaping Scientific Research Base of Upland Crops.The results showed that the main components of nine rhizome resources were in line with Chinese Pharmacopoeia 2010 Part 1;L-epicatechin content was significantly positively correlated with alcohol-soluble extract content and total ash content,but positively correlated with moisture content.Among them,five copies of rhizomes from Weining Shuanglong (Z1 ), Jinsha Pingba Lvgaoping (Z9 ),Zhijin Huaqi (Z11 ),Zhijin Guiguo (Z13 )and Jinsha Taiping (Z14 )were of higher epicatechin content than 0.04%,and higher alcohol-soluble extract content than 15.1%,which could speed up the breeding process and conducting experiments and demonstrations;Four resources from Hezhang Zhijie (Z2 ),Hezhang Zhushi (Z6 ),Jinsha Pingba Xinzhuang (Z10 )and Zhijin longchang (Z12 ) were of 0.03% ~ 0.04% epicatechin content,and 14.26% ~ 19.26% alcohol-soluble extract content, some could be used according to the breeding needs.The effects of the main components on L-epicatechin content was alcohol-soluble extract content> moisture content> total ash content,it was essential to select F.cymosum with both high contents of L-epicatechin content and alcohol-soluble extract content in cultivation and breeding.
