【摘要】通过UPLC指纹图谱,比较灯盏花及其混淆品不同药用部位的差异,结合相似度分析,为灯盏花药材鉴别和利用提供依据。
采用Agilent ZORBAX Eclipse Plius C_(18)(?2.1 mm×100 mm, 1.8μm)色谱柱,以水(含0.1%甲酸)和乙腈(含0.1%甲酸)为流动相进行梯度洗脱,流速为0.2 mL/min,检测波长为300 nm。
结果表明,建立的灯盏花指纹图谱共标定了19个共有峰;灯盏花茎、叶部与全草对照图谱无明显差异,但与花部对照图谱存在一定差异。
建立的指纹图谱方法可对灯盏花及其混
淆品加以鉴别,展苞飞蓬、多舌飞蓬与灯盏花的相似度较高,且多舌飞蓬、展苞飞蓬、狭苞紫菀、一年蓬和灯盏花花部的相似度较高。
该研究有助于灯盏花药材的鉴别和利用,可为灯盏花药材的质量控制和开发提供参考。

Why I say so is based on the following.On the one hand,if you do not work hard,good luck cannot help you in the way to success.For instance,if you want to get a high score in CET-6,you have to memorize words,study grammar,practice listening,read-ing,translating and writing and do past exam papers and exercises.If you just want to depend on good luck instead of doing the above things,it is im-possible for you to score high in CET-6.On the other hand,good luck just plays a boosting role while hard work is the foundation stone in the way to success.To conclude,it is hard work that plays a vital role in the way to suc-cess and therefore we should depend on hard work rather than luck to gain success.预测2 智商与情商Directions:For this part,you are allowed30minutes to write an essay com-menting on the topic While IQ gets you hired,EQ gets you pro-moted. You can cite examples to illustrate your point.You shouldwrite at least㊀150㊀words but no more than㊀200㊀words.41ʌ参考范文ɔWhile IQ gets you hired,EQ gets you promoted.That means that EQ is more important than IQ in the career life.It is reported that a higher sta-tus the leader is in,the more his EQ contributes.That s the reason why among many employees,who have the same educational background and the same capacity,the speed of promotion is different.The one with higher EQ well knows how to get along with others and how to control his negative emotion.A report says that the emotional quo-tient of top leaders in the companies is very high.According to the ad-vanced management concept,leadership skills are not about dominating or controlling employees,but convincing others to strive for one common goal. Under the working pressure,if one could not control his emotion or know other colleagues feelings,negative effects may be caused.As mentioned above,EQ is very important in the career life.There are several suggestions to improve EQ.First,you should know yourself well and control your emotions.Second,you should encourage yourself,espe-cially in difficult time.Third,you should learn to observe others feelings and how to get along with them.预测3 低碳生活Directions:For this part,you are allowed30minutes to write a short essay on low carbon life.You are required to write at least150wordsbut no more than200words.51ʌ参考范文ɔAs is shown above,in the middle of the drawing exists a boy,being pulled forward by his pet dog while standing on a skateboard.Reportedly, the great concern among the public has been aroused by this picture,which is thought-provoking.The absence of environmental protection has triggered significant hid-den issues that are usually ignored in our daily lives.First of all,the ways people think about environmental protection are largely determined by their degrees of education.Those with low levels of education may be easily sat-isfied by their instant interests,which fosters the lack of environmental pro-tection awareness as a lifestyle.Furthermore,with the accelerating progress of economic development,increasing amounts of time and energy are spent on work,leaving insufficient time for people to reflect upon the environment protection.Therefore,the environmental protection deficiency may be easi-ly overlooked,even when it occurs around people.To sum up,people have neglected their shortcomings for a long time,which is the major reason be-hind the emergence of the phenomenon of the insufficiency of environmental protection.With the huge success of the19th CPC National Congress,our nation has not only enhanced the enforcement of the relevant laws with regard to environmental protection but also improved the consciousness of environ-mental protection on a national scale.And young people are encouraged to cultivate the good habit of protecting the environment and make endeavors to change their lives to spare any future regret.预测4 大学生使用信用卡Directions:For this part,you are allowed30minutes to write a short essay on students use of credit cards.You are required to write at least㊀150㊀words but no more than㊀200㊀words.ʌ参考范文ɔNowadays,credit cards have been increasingly popular on campus in that banks are growingly paying their attention to students and laying out various policies to cater for students need.People hold different views61towards students owning credit cards.As far as I am concerned,it should be cautious for students to keep credit cards.Students need to be calm and wise when applying for or using credit cards.There are latent risks associated with credit cards.Some students find it quite easy to exceed their budget.They are tempted to purchase goods that they do not really need,and can become quickly overburdened by debt.The credit cards often charge a high rate of interest,which exacer-bates the problems for these people.And in the long run,this irresponsible and irrational consumption behavior will be impeditive for students to devel-op into a good consumption habit.On the other hand,when in emergency circumstances,credit cards will play its role and save you bothering relatives or friends.Credit cards can temporarily relieve your financial burden.Minimum repayment or amor-tization is a preferred alternative when you are strapped for cash.预测5 网络言论自由Directions:For this part,you are allowed30minutes to write an essay on the topic free speech on the Internet.You must give sound ar-guments to support your point of view.You should write at least㊀150㊀words but no more than㊀200㊀words.With the popularization of the Internet,it has become a common phe-nomenon that people express their ideas freely on the Internet.However, there are different voices on whether free speech should be advocated on the Internet.Some people agree that everyone should be allowed to share his or her ideas freely on the Internet.They say that since we live in a democratic country,we all have the right to free speech. However,other people argue that restrictions should be imposed on the expressions on the Internet,for there have been many remarks that spread false information and messages of violence,which has a bad influence on teenagers.In my opinion,people should be endowed with the right to speak freely on the Internet as long as we improve our moral consciousness.Internet is a71。

中药材草龙中荭草苷、异荭草苷含量的测定
曾雨娴,卢汝梅,刘美余,等.中药材草龙中荭草苷、异荭草苷含量的测定[J ].中南农业科技,2023,44(7):35-38.草龙[Ludwigia hyssopifolia (G.Don )Exell ]为柳叶菜科丁香蓼属一年生草本植物,可全草入药,味淡、性凉。
分布于中国台湾、广东、海南、广西和云南等省(自治区),野生资源十分丰富,具有清热、解毒、利尿、凉血止血之功效[1],抗菌作用明显[2]。
其在广西壮族自治区(以下简称广西)分布广泛,是壮医临床和民间长期习用的解毒药材,《广西壮族自治区壮药质量标准》记载其壮名为Gvahgya ,常用于贫痧(感冒发热)、货烟妈(扁桃体炎)、口腔炎、屙泻(泄泻)、喯咁(疳症)、呗脓(痈疮)等疾病的治疗[3,4]。
国内外对中药材草龙的化学成分、药理作用及其质量控制的研究较少。
文献报道中药材草龙中主要含有黄酮、三萜、酚类、大环内酯、生物碱、香豆素等类型化学成分[5-7]。
笔者所在的广西中医药大学药学院卢汝梅团队前期从草龙中分离鉴定出异荭草苷、荭草苷、齐墩果酸、ozoroalide 、de-O -methyl⁃lasiodiplodin 等40多种化合物[5,6]。
Rao 等[7]从草龙中分离出2α、3β、19α、6β、24-penta hydroxylurs-12-en-18-oic acid 、xanthyletin 等6种化合物,朱丹等[8]采用HPLC 法测定了不同产地草龙中没食子酸的含量,11批草龙药材没食子酸含量为0.52%~5.14%,平均为2.61%。
壮药质量标准中草龙TLC 鉴别法采用没食子酸作为指标成分[9],为草龙药材的质量评价提供了一定的科学依据。
受药材产地、采收时间等因素影响,草龙药材的化学成分种类、含量及药理作用可能存在一定差异。
《广西壮族自治区壮药质量标准》规定草龙药材中没食子酸含量不得少于0.45%,但没食子酸在中草药中广泛存在,并不具有特征性,作为草龙质量控制的指标性成分没有专属性,难以达到真正控制药材质量的目的。
荭草的功效与作用
