摘要: 羌活作为一种重要的药用植物,受野生资源的限制,开展羌活的人工栽培研究具有重要的意义。2004-2006年,在甘肃省渭源县会川野生药材驯化栽培基地开展田间试验,研究了施氮和施磷对宽叶羌活药材产量、浸出物含量和挥发油含量的影响。结果表明,羌活药材产量和挥发油含量随施氮量的增加而增加,而浸出物含量随施氮量的增加呈先增后降的变化趋势;产量随施磷量增加而增加,浸出物含量随施磷量呈先减后增的变化趋势,而挥发油随施磷量的增加呈先增后降的变化趋势。在N375kg/hm2配合P2O5600kg/hm2(N2P2)处理下羌活药材产量达最高值,较不施化肥(N0P0)增产20.39%;N300kg/hm2(N1P0)处理浸出物含量最高,较不施肥处理提高12.32%;N375kg/hm2配合P2O5450kg/hm2(N2P1)处理挥发油含量最高,较不施肥处理提高22.73%。从挥发油中共检测出89个色谱峰,分离出80种化合物,占挥发油总量的95.74%~99.32%。相对含量最高的波谱峰出现在21~22min,各处理主要化学成分的相对含量有所不同。同时还鉴定出了一些新发现的化合物。

Abstract: During 2004-2006, a field experiment in the Huichuan domestication and cultivation base of Notopterygium franchetii was conducted to study effects of nitrogen and phosphorus fertilizers on yield of N. franchetii, extract content, and essential oil content. The yield of N. franchetii gradually increased with an increase of N or P fertilization. The extract content increased initially but then decreased as N fertilization increased while the opposite happened with an increase of P fertilization. Essential oil contents increased with an increase of N fertilization; initially, it gradually increased but then it decreased with a further increase of P fertilization. The highest yield was with a treatment of N 375 kg/hm2 and P2O5 600 kg/hm2, an increase of 20.39% compared with the N0P0 treatment. The highest extract content was obtained with N 300 kg/hm2 and P2O5 0 kg/hm2, and of essential oil with N 375 kg/hm2 and P2O5 450 kg/hm2, increases of 12.32% and 22.73% respectively compared with the N0P0 treatment. GC-MS analysis of rhizomes and roots of N. incisum gave 89 peaks from which 80 compounds were identified, accounting for 95.74%-99.32% of total essential oils, most of which were terpenoids and their derivatives, mainly dutrex cluster, enols, ketones and esters. The peak of essential oil relative content was after 21-22 min, but the essential oil contents were different in all treatments. Some of the high content compounds in this plant have not previously been reported in the literature.
