    Abstract Fourteen undescribed diterpenoids caryopterisoids D - Q, three undescribed iridoid glucoside derivatives caryopterisides F - H, and 8 known diterpenoids were isolated from the 95% aqueous ethanolic extract of Caryopteris glutinosa. Their structures were elucidated on the basis of spectroscopic data analysis and chemical derivation studies. The structure and absolute configuration of caryopterisoid D were confirmed by X-ray crystallographic analysis. Caryopterisoids K and R, royleanone, 6α-hydroxydemethylcryptojaponol, and teuvincenone E were shown to reduce the biosynthesis of estrogen E2 with IC

    Abstract The internal flow problem of a reversible pump turbine restricts its safe and stable operation. Among them, the influence of the guide vane on the internal flow field is very crucial. The flow–head relationship is of great significance in the performance stability of the unit. In this study, the performance and flow field characteristics under different flow rates were analyzed for different guide vane opening angles. By comparing the results of the model test and computational fluid dynamics simulation, it was found that the simulation can well predict the energy characteristics and flow field distribution. There is an optimal efficiency range under each guide vane opening angle. The increase or decrease in flow will reduce the efficiency. For the head, it will decrease significantly with a decrease in the flow rate, especially when it deviates seriously from the optimal efficiency region. From the contour of the flow energy loss and the vector of velocity, it can be seen that the head drop is closely related to the flow blockage caused by the difference between the runner incoming flow direction and the installation direction of the guide vane. This study deeply revealed the valley and peak of head variation under different guide vane opening conditions. It can provide technical support for improving the wide range operation stability of a pump turbine.

    Abstract Fourteen undescribed diterpenoids caryopterisoids D - Q, three undescribed iridoid glucoside derivatives caryopterisides F - H, and 8 known diterpenoids were isolated from the 95% aqueous ethanolic extract of Caryopteris glutinosa. Their structures were elucidated on the basis of spectroscopic data analysis and chemical derivation studies. The structure and absolute configuration of caryopterisoid D were confirmed by X-ray crystallographic analysis. Caryopterisoids K and R, royleanone, 6α-hydroxydemethylcryptojaponol, and teuvincenone E were shown to reduce the biosynthesis of estrogen E2 with IC₅₀ values from 0.25 to 3.06 μM in cell-based estrogen biosynthesis assays system.

    Abstract Relativistic density functional theory (DFT) calculations of the geometries and Au-P bonding of W@Au(12)PX(3) (X = H, F, Cl, Br, I, Me, OMe) and [M@Au(12)](q)PH(3) (M(q) = Hf(2-), Ta(-), W, Re(+), Os(2+), Ir(3+), Pt(4+), Au(5+)) have been carried out. There are some regular changes in geometry and binding of these two kinds of complexes with the variation of the phosphanes PX(3) and transition metals M(q). The energy decomposition analysis confirms that the PX(3) ligands are sigma donors. The donor tendency (DeltaE(sigma)/DeltaE(pi)) decreases for different X with increasing electronegativity and for different M(q) from Au(5+) to Hf(2-), while the pi-back-donation increases in the same direction. The calculated P-H bond lengths show a regular decrease from Hf(2-) to Ir(3+), but have abnormal trends for Pt(4+) and Au(5+).
