第三章，根據一種常見的病毒煙草花葉病毒（ tmv ）的核酸序列設計了分子信標熒光探針，由於tmv的遺傳物質是rna ，分子信標又具有很高的特異性和靈敏度，因此感染了病毒粒子的植物葉片在經過簡單處理后，可用分子信標檢測葉片上。Abstract : aim to synthesize a new prodrug, resveratrol trinicotinate. methods in presence of lithium and a catalytic amount of naphthalene, the reaction of p - methoxybenzyl trimethylsilyl ether and 3, 5 - dimethoxylbenzaldehyde gave resveratrol after a series of translation. resveratrol trinicotinate was obtained by the reaction of resveratrol and nicotinoyl chloride hydrochloride. results a mutual prodrug resveratrol trinicotinate was designed and synthesized. conclusion a novel method for synthesis of resveratrol and resveratrol trinicotinate has been afforded. the e - isomer is selectivily obtained by dehydration of the compound 2 with khso4
文摘:目的合成一種前藥白藜蘆醇煙酸酯.方法在金屬鋰片和催化量的萘的存在下， 3 ， 5 -二甲氧基苯甲醛與對甲氧基苯甲醇的三甲基硅醚反應經過一系列轉變得到白藜蘆醇，白藜蘆醇與煙酰氯反應得到白藜蘆醇煙酸酯.結果設計併合成了白藜蘆醇煙酸酯.結論提供了一種合成白藜蘆醇及白藜蘆醇煙酸酯的方法，採用khso4脫水可選擇性的得到反式產物Effects of 6 - benzyladenine and abscisic acid on the photosynthetic function and hydrogen peroxide content in tobacco leaves of different development phase
