为了降低人工栽培北细辛（Asarum heterotropoides ）中的主要毒性成分马兜铃酸 A 含量，采用田间试验研究了不同遮阴度对3年生北细辛中马兜铃酸 A 含量的影响。结果表明：在北细辛根适宜采收的8月，50％、70％、90％遮阴度北细辛中马兜铃酸 A 的平均含量分别为0．25628 mg／g、0．25988 mg／g、0．26108 mg／g，含量差异不显著。同一遮阴度下随着遮阴时间的延长马兜铃酸 A 含量呈降低趋势，不同遮阴度随着遮阴时间的延长马兜铃酸 A 含量存在一定差异。综合考虑成本用工等，以50％遮阴度最经济，马兜铃酸 A 含量也最低。
為瞭降低人工栽培北細辛（Asarum heterotropoides ）中的主要毒性成分馬兜鈴痠 A 含量，採用田間試驗研究瞭不同遮陰度對3年生北細辛中馬兜鈴痠 A 含量的影響。結果錶明：在北細辛根適宜採收的8月，50％、70％、90％遮陰度北細辛中馬兜鈴痠 A 的平均含量分彆為0．25628 mg／g、0．25988 mg／g、0．26108 mg／g，含量差異不顯著。同一遮陰度下隨著遮陰時間的延長馬兜鈴痠 A 含量呈降低趨勢，不同遮陰度隨著遮陰時間的延長馬兜鈴痠 A 含量存在一定差異。綜閤攷慮成本用工等，以50％遮陰度最經濟，馬兜鈴痠 A 含量也最低。

In order to reduce the content of aristolochic acid A that is the mian toxic components in A.heterotropoides,3 years old A.heterotropoides was covered by different degree of shade by a field trial,to research the effects of different shade levels on the content of aristolochic acid A in A. heterotropoides.The results showed that aristolochic acid A content of A.heterotropoides in the 50%, 70% and 90% shade levels was 0.256 28 mg/g,0.259 88 mg/g,0.261 08 mg/g during the suitable harvest period,respectively.Moreover,they were not significant.The differences of aristolochic acid A content in A.heterotropoides were declined in the same shade level,while the differences of aristolochic acid A content in A.heterotropoides were also different in the different shade level with the extension of time.The effects of 50% shade were the best by considering the cost of labor.
