TL;DR: Several flavonoids were isolated from the leaves of Polygonum filiforme var. neofiliforme, flaccidum, P. senticosum as mentioned in this paper.
Abstract: Several flavonoids were isolated from the leaves of Polygonum filiforme var. neofiliforme, flaccidum, P. Blumei, P. Y o kusaianum, and P. senticosum. Their structures we re identified as myricetin 3-rhamnoside, quercetin 3-(2-O-galloylrhamnoside), quercetin 3-rutinoside, quercetin 3-rhamnoside, kaempferol 3-glucoside, isorhamnetin, quercetin, and apigenin 7(glucuronide 6-methyl ester) by the comparison of their TLC, HPLC, and spectroscopic data with those of the authentic samples. It was clarified that quercetin 3-(2-O-galloylrhamnoside)is distributed in P. filiforme var. neofiliforme and P. flaccidum.

TL;DR: 본 연구는 하수오 표고균사(Lentinula edodes JMI-10079) £25^{\circ}C$, pH 5~8의 탐색을 목적으로 수행하 무기�
Abstract: This study was performed to determine the optimal condition for Lentinula edodes JMI-10079 mycelium cultivation on the root of Polygonum multiflorum. We also analyzed the proximate composition, total amino acids, and minerals in the root of P. multiflorum cultivated with L. edodes JMI-10079 mycelia. The optimal temperature and pH for L. edodes JMI-10079 mycelium cultivation on the P. multiflorum root were 25oC and pH 5–6 respectively, whereas the optimal carbon and nitrogen sources were glucose and maltose, respectively. The content of crude protein, crude fat, and ash in the P. multiflorum root cultivated with L. edodes JMI-10079 mycelia was higher than that in the uncultivated P. multiflorum root. The content of crude fiber was the highest in the control. Total amino acid analysis revealed that the contents of total amino acids and total essential amino acids were increased by higher root of P. multiflorum concentration.

TL;DR: This is the first systematic study on the chemical constituents of Polygonum cuspidatum and its metabolic profile in vivo, which contributes to finding its bioactive components and seeking its therapeutic targets.
Abstract: Polygonum cuspidatum Sieb. et Zucc. is a traditional and popular Chinese medicine with a wide spectrum of pharmacological effects such as anti-bacterial, anti-inflammatory, and anti-tumor activities together with other health effects like lowering lipids, preventing diabetes, and regulating the immune system. It is of great significance to explore the complex chemical constituents and metabolic process of Polygonum cuspidatum in vivo to further clarify the effective substances. However, studies on its metabolism in vivo were not comprehensive in previous literature. In this study, ultra-high performance liquid chromatography coupled with Quadrupole-Exactive Orbitrap mass spectrometry was used to comprehensively identify the chemical constituents in Polygonum cuspidatum and further analyze its metabolic profile in rats. Compared with reference substances, various databases, and literature retrieval, 62 compounds were inferred from the Polygonum cuspidatum extract. Furthermore, a total of 119 compounds, including 44 prototype compounds and 75 metabolites, were annotated in rat plasma, urine, and feces. The main metabolic pathways of Polygonum cuspidatum in rats included hydrogenation reduction, hydroxylation, dehydration, methylation, sulfation, and glucuronidation. This is the first systematic study on the chemical constituents of Polygonum cuspidatum and its metabolic profile in vivo, which contributes to finding its bioactive components and seeking its therapeutic targets.
