Two New Taxanes fromTaxus chinensisvar.mairei
Planta Medica, 1998Two bicyclic taxanes and two abeotaxanes were isolated from the bark and the needles of the Chinese yew, Taxus chinensis var. mairei. The structures of the two new compounds, 5-( N,N-dimethyl-3'-phenylisoseryl)taxachitriene A and 13-acetyl-9-deacetyl-9-benzoyl-10-debenzoyltaxchinin A, were established by spectral methods.

TcJAMYC5 positively regulates paclitaxel biosynthesis in Taxus chinensis var. Mairei
Plant Molecular BiologyPaclitaxel is an important natural anticancer drug. Its biosynthesis is very complex and 18 enzymes likely involved have been characterized. However, the regulatory mechanism of these enzyme genes still remains to be elucidated. Here we identified a novel transcription factor in the MYC family of Taxus chinensis TcJAMYC5 function in paclitaxel ...

Control of hypertension in rats using volatile components of leaves of Taxus chinensis var. mairei
Journal of Ethnopharmacology, 2012The leaves of Taxus chinensis var. mairei (Taxaceae) is used traditionally to fill pillows in some rural areas of China. Its volatile substances have been speculated to be capable of improving sleep quality, making blood pressure stable, and having diuretic capacity as recorded in Ancient Chinese Materia Medica. Using animal models and new technologies,

[Chemical constituents of bark of Taxus chinensis var. mairei].
Zhong yao cai = Zhongyaocai = Journal of Chinese medicinal materials, 2015To study the chemical constituents in the bark of Taxus chinensis var. mairei collected from southeast of China.Chemical constituents were isolated and purified by column chromatography, Prep-TLC, and preparative HPLC. The structures were identified on the basis of 1D-and 2D-NMR spectral analysis.Twelve taxane diterpenoids were isolated from the bark ...

The biological responses of Taxus chinensis var. mairei suspension cultures to a range of shear rates were investigated in a Couette-type shear reactor. It was found that the shear rate below 458 s-1 enhanced the primary metabolism, increasing mitochondrial activity and protein expression and inhibiting the activity of phenylalanine ammonia lyase (PAL),
