Fifteen undescribed diterpenoid alkaloids and seven known analogs were coisolated from the whole plant Aconitum tanguticum (Maxim.) Stapf. Their structures were elucidated based on spectroscopic methods. Among them, tangirine A was a heteratisine-hetidine-type bis-diterpenoid alkaloid, tanguticinines A-F were six hetidine-hetisine-type bis-diterpenoid alkaloids, tanguticinine G was one hetidine-atisine-type bis-diterpenoid alkaloid, and N-oxide anthoroidine B, 5-deoxyanthoridine B and N-oxide 5-deoxyanthoroidine B were three unusual hetidine-rearranged hetisine-type bis-diterpenoid alkaloids. In the bioassay, thirteen compounds showed some inhibitory effects on the secretion of NO and TNF-α in LPS-treated RAW 264.7 cells, with IC 50 values of 67.56 μM-683.436 μM., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Elsevier Ltd.

In this study, nanocubes KTaO 3 -reduced graphene oxide (rGO-KTaO 3 ) photocatalysts were synthesized by a facile hydrothermal method. Different technical methods were carried out to characterize the as-prepared compounds. UV-Vis spectra show that the absorption sideband of the complexes red-shift to visible light region, which enhances the light utilization. Meanwhile, X-ray photoelectron spectroscopy (XPS) reveals that the graphene oxide (GO) in the composite has been partially reduced, leading to more effective electron transport and thus improving the photocatalytic efficiency. Furthermore, photocatalytic degradation efficiency of Methylene blue (MB) and Rhodamine B (RhB) in the presence of rGO-KTaO 3 reaches 96% and 98%, which is 10 times of that of KTaO 3 . The synthesized rGO-KTaO 3 has good photocatalytic properties. Moreover, the stability of this photocatalyst is particularly excellent. The detailed mechanism of photocatalysis has been carefully discussed in the article., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2020 Elsevier B.V.
