[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),

[Structure and dynamics of Taxus chinensis var. mairei clonal population].
Ying yong sheng tai xue bao = The journal of applied ecology, 2004Structure and dynamics of Taxus chinensis var. mairei clonal population were studied. The results showed that according to the life history of Taxus chinensis var. mairei, the modular population could be divided into 6 classes. The development of Taxus chinensis var.

The study was conceived to evaluate the difference in the chemical composition as well as the difference in the antimicrobial activities of the essential oils of Taxus media and Taxus chinensis var. mairei leaves. The chemical composition of essential oils which obtained by hydrodistillation method, were analysed by gas chromatography-mass spectrometry

Two novel pseudoalkaloid taxanes from the Chinese yew, Taxus chinensis var. mairei
Phytochemistry, 1999Abstract Two pseudoalkaloid taxane diterpenoids were isolated from seeds of the Chinese yew tree Taxus chinensis var. mairei. Their structures were established as 2α,9α,10β,13α-tetraacetoxy-5α(3′-methylamino-3′-phenyl)-propionyloxy-taxa-4(20),11-diene and 7β,9α,10β,13α-tetraacetoxy-5α(3′-methylamino-3′-phenyl)-propionyloxy-taxa-4(20),11-diene, with ...

[Root microstructure and distribution of the endophytic fungi in Taxus chinensis var. mairei].
Zhongguo yi xue ke xue yuan xue bao. Acta Academiae Medicinae Sinicae, 2007To study the root microstructure and the distribution of the endophytic fungi in Taxus chinensis var. mairei.The roots of Taxus chinensis var. mairei at nature were cut with paraffin, dyed and observed by microscope.The secondary structure of the roots of Taxus chinensis var. mairei consisted of the periderm and vascular cylinder (stele).

Taxoids profiling of suspension Taxus chinensis var. mairei cells in response to shear stress
Biochemical Engineering Journal, 2013To develop an optimal bioprocess for paclitaxel (Taxols) supply, taxoid biosynthetic pathway regulation must be better understood. The main taxoid metabolites (paclitaxel, baccatin III, taxol C, etc.) in Taxus cell culture showed great difference under shear stress.
