烟碱酸

Burley tobaccos have a low carbohydrate content of nitrogenous materials, nicotine, and nonvolatile acids.

白勒烟 含有较低的碳水化合物和含氮化合物，烟碱和非挥发性酸。

Assulta and the induction of GST activity by nicotine and capsicine in H. assulta provided partial supports for the hypothesis that diet breadth was governed by detoxification abilities. The results also indicated that two sibling species had different strategies of adaptation to toxic substances: H. assulta saves expenditure of nutrients and energy by restricting their countermeasures to a few potentially toxic compounds. H. armigera, by contrast, must be prepared to counter a wider range of potential toxins. 5. Compared with parental species, hybrids of reciprocal hybridization had significant difference in feeding preference for hot pepper.

结果显示，广食性的棉铃虫在中肠羧酸酯酶和谷胱甘肽-S-转移酶活性方面高于寡食性的烟青虫，但烟青虫谷胱甘肽-S-转移酶活性可以被寄主植物内的烟碱和辣椒素所诱导，表明解毒酶活性在一定程度上影响着植食性昆虫的食性广度；同时也暗示着二近缘种对有毒的次生物质采取不同的适应策略：烟青虫有选择地对付种类较少的植物次生物质以减轻营养和能量的消耗；棉铃虫则必须对付存在于其寄主植物内的种类繁多的有毒次生物质。

The results showed that there were 8 kinds of aliphatic, 5 kinds of esters, 2 kinds of aldehydes, 2 kinds of nitrogen sulfur heterocyclic rings and one kind of hydrocarbon, alcoholics, ketone, lactones respectively in the analyzed 21 kinds of aroma components, and the content of furfural,β-methyl valeric acid, palmitic acid, nicotine, neohytadiene were higher, next were acetyl ethyl propionate, caleric acid, phenyl ethyl acetate, hydroxylic diethyl succinate.

结果表明，在分析出的21种香气成分中，分别有脂肪酸类8种，酯类5种，醛类2种，氮硫杂环类2种，烃类、醇类、酮类、内酯类各l种，其中相对含量较高的物质成分是糠醛、β-甲基戊酸、十六碳酸、烟碱、新植二烯，其次是乙酰丙酸乙酯、异戊酸、苯乙酸乙酯、羟基丁二酸二乙酯等。

Assulta are dosely related species in Noctuidae and their larvae are both polyphagous.

本项工作是在人工饲料中分别加入0.5％的烟碱、番茄苷、棉子酚、丹宁酸等饲养早期六龄的幼虫，测定它们对生长和食物利用的影响。

In this study, the cDNA fragments encoding α subunit of nicotinic acetylcholine receptor was cloned from the diamond back moth, Plutella xylostella with RT-PCR techniques. The amplified fragments are 425 nucleotides in length, from which 141 amino acids were deduced.

测序结果显示，扩增的目的基因片段包含了nAChRα亚基的三种亚型，分别命名为Pxal、Pxa2、Pxa3，都具有典型的α亚基的结构：两个相邻的半胱氨酸；形成胞外环的15个氨基酸；与烟碱和α银环蛇毒素结合有关的氨基酸残基。

Oriental tobaccos are low in nicotine, median in carbohydrates and nitrogenous

烤烟的特点是含糖量高，而含氮化合物、酸类和烟碱的含量中等偏下。

The susceptibilities of the 3th instar larvae of Spodoptera litura fed on diets treated with nicotine and rutin to AucaNPV, fipronil and spinosad were studied. The activities of CarE and GSTs in different treated cutworms were also tested. The results showed that the nicotine enhanced significantly the susceptibility of Spodoptera litura to insecticides, and the susceptibility enhanced as the nicotine concentration in the diets increased.

以在人工饲料中添加植物次生物质的方法，研究了取食不同含量烟碱、芸香苷的斜纹夜蛾Spodoptera litura 3龄幼虫对银纹夜蛾核多角体病毒、氟虫腈及多杀菌素的敏感性，同时测定了各处理组幼虫体内羧酸酯酶和谷胱甘肽转移酶的活性。

Nicotinic acid, which is also called niacin, is a water soluble vitamin B. It improves levels of all lipoproteins when the doses are given far above the vitamin requirement.

烟酸，也被称为烟碱酸，是一种水溶性维生素B ，提高水平的所有脂蛋白的剂量时，给出了远远高于维生素的要求。

The effects of leaf spraying with aqueous solution of Gibberellic Acid (GA_3) in different concentration on the length, width and thickness of upper leaf of new K326, a flue-cured tobacco breed, were studied.

研究了植物生长调节剂赤霉酸(GA3)水溶液叶面喷施对烤烟品种新K326上部烟叶长度、宽度及厚度的影响，并探讨了外源GA3喷施浓度与上部烟叶烟碱含量及糖碱比值间的关系、GA3喷施浓度与烟叶等级结构和产值间的关系。
