Abstract

Summary: To enhance the cycling ability and rate property of carbon anode material for sodium ion battery, an easy, green, and scalable thermal pyrolysis method had been exploited to synthesize the nitrogen, sulfur self‐doped porous carbon anode derived from the walnut shell. The microstructure and electrochemical properties of this synthesized porous carbon materials are investigated by tuning the thermal pyrolysis temperature. When it is at 1000 °C, the porous carbon material exhibits the largest average interlayer distance of about 0.408 nm (d002) and excellent electrochemical performance. The porous carbon electrode material carbonized at 1000°C for sodium ion battery manifests a high reversible specific capacity of about 305 mAh g−1 at a current density of 100 mA g−1 after 200 cycles, and as large as 182 mAh g−1 at 1 A g−1 after 1500 charge/discharge cycles. Nitrogen and sulfur doped biomass carbon anode material with an excellent storage capacity for sodium ion, makes it an appealing candidate as cheap and high‐performance anode materials for sodium ion batteries.

Abstract

The quantitative analysis of multi-components with single marker (QAMS) method was firstly established for simultaneous determination of six triterpenoid saponins (ilexgenin A (C1), ilexsaponin A1 (C2), ilexsaponin B1 (C3), ilexsaponin B2 (C4), ilexsaponin B3 (DC1), ilexoside O (DC2)) in Ilex pubescensby Ultra Performance Liquid Chromatography (UPLC) and High Performance Liquid Chromatography (HPLC). Using C1 as the internal reference, the relative correction factors (RCF) of the other five triterpenoid saponins were calculated and statistically evaluated. The durability of the method was verified with five different LC instruments and five different C18columns under various chromatographic conditions. The external standard method after methodology verification was chosen to check the accuracy and feasibility of the QAMS method. The results showed that the RCFs of all compounds were obtained with good reproducibility (RSD < 5.0%), whether on different chromatography instruments or under various chromatographic conditions. The relative retention value method could be adopted for accurately positioning the chromatographic peak of the six constituents, with their values of RSD ranging between 0.5% and 1.6%. Meanwhile, no significant differences were found in the quantitative results of the six saponins in nine batches of medicines calculated by the QAMS method and external standard method, whether on a HPLC system or UPLC system. The QAMS method established in our research for simultaneous determination of the six saponins is accurate and can be feasibly used to evaluate the quality of Ilex pubescens, especially when the standard substance is inconvenient to obtain.

Abstract

Two new triterpenes and five new triterpene saponins, named ilexpusons A-G ( 1 - 7 ), as well as eight known compounds were isolated from Ilex pubescens . The structures of the new compounds were established by a combination of chemical and spectroscopic methods, including HRESIMS, 1 H-NMR, 13 C-NMR, 1 H- 1 H COSY, HSQC, HMBC, and NOESY. Additionally, the biological activity of compounds 1  -  15 against adenosine diphosphate-induced platelet aggregation in rabbit plasma was determined. Among the tested compounds, 1, 2, 5, 6, 8, 13, 14 , and 15 exhibited significant inhibition of platelet aggregation in vitro ., Competing Interests: Conflict of Interest: The authors declare that no competing financial interests., (Georg Thieme Verlag KG Stuttgart · New York.)
