【文章內(nèi)容簡介】 草烯、癸醛、癸醇、1,4,4a,5,6,6,7,8a八氫2,5,5,8a四甲基1萘甲醇、8溴新異長葉烯、Z,Z,Z1,5,9,9四甲基1,4,7,環(huán)十一碳三烯、藍桉醇、(Z)β金合歡烯、十一醛、羅漢柏烯。其中香氣成分主要有:肉豆蔻醛、月桂醛、月桂醇、葎草烯、癸醛、癸醇、十一醛、 (Z)β金合歡烯。在三種不同的提取方法中,固相微萃取法所提取得揮發(fā)油成分種類多,操作簡單,提取耗時少,有利于揮發(fā)油產(chǎn)品的在線檢測;水蒸汽蒸餾提取法比微波輔助提取法更利于對魚蓼揮發(fā)油的提取。表現(xiàn)在四個方面:儀器簡單,價格便宜;化合物的種類多,含香氣成分多,含量高;醛類、烯類和醇類化合物比例均衡;提取率略高。 參考文獻[1] 汪勁武. 說不盡的蓼科植物(上).植物雜志[J].1996,04(2):2729[2] 丁寶章,王遂義, 冊[M].鄭州: 河南科學技術(shù)出版社,1997.[3] [M].上海: 上??茖W技術(shù)出版社, 1999.[4] [J].中醫(yī)藥學刊,2001,19 ( 6) : 643.

With heaps of time, the sevenday Chinese請您刪除一下內(nèi)容,O(∩_∩)O謝謝!?。ational Day holiday could be the best occasion to enjoy a destination. However, it can also be the easiest way to ruin how you feel about a place and you may bee more fatigued after the holiday, due to battling the large crowds. During peak season, a dream about a place can turn to nightmare without careful planning, especially if you travel with children and older people. As most Chinese people will take the holiday to visit domestic tourist destinations, crowds and busy traffic are inevitable at most places. Also to be expected are increasing transport and acmodation prices, with the possibility that there will be no rooms available. It is also mon that you39。llwait in the line for one hour to get a ticket, and another two hours at the site, to only see a tiny bit of the place due to the crowds. Last year, 428 million tourists traveled in China over the weeklong holiday in October. Traveling during this period is a matter that needs thorough preparation. If you are short on time to plan the uping Golden Week it may not be a bad idea to avoid some of the most crowded places for now. There is always a place so fascinating that everyone yearns for. Arxan is a place like this. The beauty of Arxan is everlasting regardless of the changing of four seasons. Bestowed by nature, its spectacular seasonal landscape and mountains are just beyond word. Arxan is a crucial destination for the remended travelling route, China Inner Mongolia Arxan — Hailar — Manzhouli.
