苯基肉桂酸 的英文怎麼說
中文拼音 [běnjīròuguìsuān]
苯基肉桂酸
英文
phenyl-cinnamic acid-
With 24 c or 4 c, the change trends of the content of the salidroside was basically consentaneous in the consecutive cultural eras of the callus. in the callus from the different explants, the influence was maximal to the the activity of pal enzyme and the influence was lowest to the the activity of ca4h enzyme, and the influence to the the activity of tal enzyme was ascertained according to the explant of the callus. so in the same explant with the different temperature or in the different explant with the same temperature, there was no incident between the content of the salidroside and the activity of enzymes pal, ca4h and tal, and we presumed that there may be emphasized particularly on different metabolic pathway of salidroside
（ 2 ） 、愈傷組織的外植體來源、培養溫度條件和不同的繼代培養數都影響著其中紅景天甙的含量和苯丙氨酸解氨酶（ pal ） 、肉桂酸解氨酶（ ca4h ）和酪氨酸解氨酶（ tal ）這3種酶的活性；不管是葉來源還是莖來源，不管是24培養還是4培養的愈傷組織，在連續繼代培養中紅景天甙含量的變化趨勢基本上是一致的；無論是葉來源的愈傷組織還是莖來源的愈傷組織，培養溫度對pal酶的酶活性影響最大，對ca4h酶的酶活性影響最小，對tal酶的酶活性影響視不同的外植體來源而定；在相同外植體來源的愈傷組織中及不同的培養溫度的條件下，或是在不同外植體來源的愈傷組織中及相同溫度的培養條件下，其紅景天甙含量與pal酶、 ca4h酶和tal酶的酶活性之間沒有完全一致的對應伴隨關系。Abstract : the phenyl lithium, 2 - methoxy phenyl lithium and 2, 4 - dimethoxy phenyl lithium reacted with the cinnamic acid to produce a corresponding chalcone in 75 %, 56 %, 50 % yield, respectively. 2, 6 - dimethoxyphenyl lithium could not react with cinnamic acid, but reacted with methyl cinnamate to produce 2 ， 6 - dimethoxychalcone
文摘:苯基鋰、 2 -甲氧基苯基鋰和2 ， 4 -二甲氧苯基鋰分別與肉桂酸反應以75 ， 65 ， 50的收率生成相應的查爾酮； 2 ， 6 -二甲氧基苯基鋰與肉桂酸不發生反應，但能與肉桂酸甲酯反應生成2 ， 6 -二甲氧基查爾酮；類似的還制得了2 ， 4 ， 6 -三甲氧基查爾酮和2 ， 4 ， 4 ， 6 -四甲氧基查爾酮。
