“…AM inhibited mitochondrial oxygen consumption and malondialdehyde (MDA) production [14]. Recently, most of the constituents including triterpene saponins, isoflavonoids, and polysaccharides were isolated from AM, and their bioactive effects were also investigated [15,16]. As an important bioactive component of AM, Astragalus polysaccharides (APS) have immunoregulatory, antiviral, hypoglycemic, antioxidant, and antitumor properties [17–20].…”

The current study was performed to investigate mitochondrial protection and anti-aging activity of Astragalus polysaccharides (APS) and the potential underlying mechanism. Lipid peroxidation of liver and brain mitochondria was induced by Fe2+–Vit C in vitro. Thiobarbituric acid (TBA) colorimetry was used to measure the content of thiobarbituric acid reactive substances (TBARS). Mouse liver mitochondrial permeability transition (PT) was induced by calcium overload in vitro and spectrophotometry was used to measure it. The scavenging activities of APS on superoxide anion (O2•−) and hydroxyl radical (•OH), which were produced by reduced nicotinamide adenine dinucleotide (NADH)—N-Methylphenazonium methyl sulfate (PMS) and hydrogen peroxide (H2O2)–Fe2+ system respectively, were measured by 4-nitrobluetetrazolium chloride (NBT) reduction and Fenton reaction colorimetry respectively. The Na2S2O3 titration method was used to measure the scavenging activities of APS on H2O2. APS could inhibit TBARS production, protect mitochondria from PT, and scavenge O2•−, •OH and H2O2 significantly in a concentration-dependent manner respectively. The back of the neck of mice was injected subcutaneously with D-galactose to induce aging at a dose of 100 mg/kg/d for seven weeks. Moreover, the activities of catalase (CAT), surperoxide dismutase (SOD) and glutathione peroxidase (GPx) and anti-hydroxyl radical which were assayed by using commercial monitoring kits were increased significantly in vivo by APS. According to this research, APS protects mitochondria by scavenging reactive oxygen species (ROS), inhibiting mitochondrial PT and increasing the activities of antioxidases. Therefore, APS has the effect of promoting health.

“…Other components existing in BS or AM could also affect enzymatic activities for the biosynthesis of the major components, including trace elements, phenolic compounds, isoflavones, anthocyanins, saponins, etc. [434445464748] Therefore, our study will be as an interesting reference for future investigators to study the change of the active compounds in the fungi fermentation products cultivated in a medium containing BS and AM.…”

The antihepatoma activity and liver protective function of the fermentation products (5 L fermenator) of Ganoderma lucidum (GL; 靈芝 Ling Zhi) cultivated in a medium containing black soybean (BS; 黑豆 Hēi Dòu) and Astragalus membranaceus (AM; 生黃耆 Shēng Huáng Qí) at different fermentation temperatures were investigated in this study. Hep 3B cells pretreated with lovastatin were used to study the antihepatoma activity, and possible active components were analyzed by reverse-phase high-performance liquid chromatography. Carbon tetrachloride (CCl4)-induced primary rat hepatocyte injury was further used to evaluate the liver protective activity of the fermentation products. While all the GL broth filtrates do not inhibit the growth of Hep 3B cells, the ethanolic extract from GL-2 mycelia (GL-2-mE), cultivated in the medium containing BS (50 g/L) and AM (20 g/L) at 24°C for 11 days showed the best antihepatoma activity (IC50 26.6 μg/mL) than the other ethanolic extracts from GL mycelia, GL fruiting body, BS, and AM did. The antihepatoma activities were correlated with some unknown active components in these samples. Furthermore, GL-2-mE (100 μg/mL) without harmful effect on the growth of normal primary rat hepatocytes significantly maintained cell viability, reduced lactate dehydrogenase leakage, lowered lipid peroxidation, and increased glutathione peroxidase and glutathione S-transferase activities in the CCl4-induced damaged primary rat hepatocytes.

From the 95% EtOH extract of dried aerial parts of Clematis tashiroi, eight new and four known phenolic (caffeic acid, coumaric acid, ferrulic acid) glycosides were isolated and characterized. The structures of the new isolates (clematisides A-H) were elucidated by spectroscopic data interpretation as trans-4-O-(6-O-trans-caffeoyl-β-D- glucopyranosyl)-9-O-β-D-glucopyranosyl caffeic acid (1), trans-4-O-(6-O-trans-feruloyl-β-D-glucopyranosyll)-9-O-β-D-glucopyranosyl caffeic acid (2), trans-4-O-(6-O-trans-p-coumaroyl-β-D-glucopyranosyl)-9-O-β-D-glucopyranosyl caffeic acid (3), trans-4-O-(6-O-trans-caffeoyl-β-D-glucopyranosyl)-9-O-β-D-glucopyranosyl p-coumaric acid (4), trans-3-O-(6-O-trans-caffeoyl-β-D-glucopyranosyl)-9-O-β-D-glucopyranosyl caffeic acid (5), trans-3-O-(6-O-trans-p-coumaroyl-β-D-glucopyranosyl)-9-O-β-D-glucopyranosyl caffeic acid (6), 6-(3',4'-dihydroxystyryl)-2-pyrone-4-O-(6-O-trans-caffeoyl)-β-D-glucopyranoside (7), and 6-(3',4'-dihydroxystyryl)-2-pyrone-4-O-{6-O-[4-O-(6-O-trans-caffeoyl)-β-D-glucopyranosyl]-trans-caffeoyl}-β-D-glucopyranoside (8), respectively. In a DPPH radical-scavenging test, compounds 1, 7, and 8 showed more potent antioxidant activity than that of the positive control, vitamin E. In addition, compound 7 also showed inhibitory activity in an antinitric oxide release assay.
