Investigation of the lower molecular weight phenolics from the needles of Taxus cuspidata led to the isolation and structural elucidation of (+)-catechin, (-)-epicatechin and (+)-catechin-(5,6-bc)-4beta-(4''-hydroxyphenyl)-dihydro-2(H)-pyranone (1), a new phenylpropanoid flavan-3-ol. The structures of these compounds were established on the basis of chemical and spectroscopic evidence.

Plants make complex and potent therapeutic molecules, but difficulties in sourcing from natural producers or chemical synthesis can challenge their use in the clinic. A prominent example is the anti-cancer therapeutic paclitaxel (Taxol). Identification of the full paclitaxel biosynthetic pathway would enable heterologous drug production, but it has eluded discovery despite a half century of intensive research.

Baccatin III is a crucial precursor in the biosynthesis pathway of paclitaxel. Its main sources are extraction from or chemical synthesis using 10-deacetylbaccatin III (10-DAB) as substrate. However, these preparation approaches exhibit serious limitations, including the low content of baccatin III in and the complicated steps of chemical synthesis.

Taxanes are the best-known compounds in owing to their strong anticancer effects. However, the traditional taxanes extraction method is the solid-liquid extraction method, which is limited by a large energy consumption and low yield. Therefore, it is urgent to find an efficient method for taxanes extraction.

is a rare and endangered woody plant worldwide with important economic and ecological values. However, the weak environmental adaptability of species, in particular the unstable photosynthetic activity in different seasons, always affects its normal growth and development and limits its conservation and exploitation. To improve the survival of trees in cultivated areas, the seasonal dynamics of chlorophyll fluorescence (CF) and key physiological parameters were comprehensively investigated in and .
