红豆杉醇

But the addition of the rare earth compound could not strengthen further taxol release in the two-liquid-phase cultures of Taxus cuspidata.

但在红豆杉细胞两液相培养中，稀土加入不能进一步促进紫杉醇的释放。

Methods: from prepation of crude drug as start, study the technology of extract and defat with L9 (3~4) orthogonal test. With EtOH extraction and water sed, alkali washing, EtOAC extraction as main methods of eliminate dopant. Finally with alky AlzO3 chromatographic column, rich and gain anticancer active site. The maximum response was achieved at a 40 min extracting time with 10 times volume 90% EtOH added to the sample for the first time and 30 min for the second time. Adding 10 times water will produce precipitation; Place the precipitation into 6 times petroleum benzin to de-fat at 60℃.

云南红豆杉中抗癌活性物制备工艺研究方法：利用正交设计试验L9(3~4)确定原料药提取工艺为：10倍量90％乙醇提取两次，第一次40分钟，第二次30分钟；醇提液用10倍量水沉；沉淀加6倍量石油醚40℃脱脂；用1mol／L的NaOH溶液碱洗，除去酸性杂质；以碱性氧化铝柱，以环己烷／丙酮为洗脱溶剂，在环己烷-丙酮(6：4)段富集到所需活性部位，洗脱剂用量为3VB。

Those results provided guidance for further research on mechanism of elicitation and regulation of taxol biosynthesis in Taxus cells.

这些结果为诱导作用机理及调控红豆杉细胞合成紫杉醇的研究具有指导意义。

Effects of the treatments of 50 mg·L -1 fungal elicitor (F 5),50 mg·L -1 salicylic acid and 50 mg·L -1 F 5+50 mg·L -1 SA on membrane-lipid peroxidation and taxol production in Taxus chinensis suspension cell cultures were studied.

研究了 5 0 mg· L- 1真菌诱导子(F5)，5 0 mg· L- 1水杨酸，5 0 mg· L- 1F5+5 0 mg· L- 1SA3种处理，对红豆杉悬浮细胞膜脂过氧化和紫杉醇合成的影响。

The institute is the first company built Media Taxus plant basis in Southeast China, and has a hectares of 300 hectares Media Taxus and 2000 hectares Giant Knotweed.

研究所是西南地区最早建立曼地亚红豆杉种植基地的企业，种植面积达4200亩，有24000亩白藜芦醇原料━虎杖的种植生产基地。

Taxol, a diterpenoid secondary product from the bark of yew species, has been approved an efficient anti-cancer drug for breast cancer and some other tumor diseases.
