Research on the quality markers of antioxidant activity of Kai-Xin-San based on spectrum-effect relationship

ABSTRACT: Kai-Xin-San (KXS) is one of the classic famous traditional Chinese medicine prescriptions for amnesia, which has been applied for thousands of years. Modern pharmacological research has found that KXS has significant therapeutic efficacy on nervous system diseases, which is related to its antioxidant activity. However, the antioxidant material basis and quality markers (Q-makers) of KXS have not been studied. The objective of this study is to explore the Q-makers of antioxidant activity of KXS based on spectrum-effect relationship. Specifically, the metabolites in KXS extracts were identified by UPLC-Q-Exactive Orbitrap MS/MS. The fingerprint profile of KXS extracts were established by high-performance liquid chromatography (HPLC) and seven common peaks were identified. Meanwhile, 2, 2-diphenyl-1-picrylhydrazyl (DPPH) test was used to evaluate the free radical scavenging ability of KXS. The spectrum-effect relationship between its HPLC fingerprint and DPPH free radical scavenging activity was preliminarily examined by the Pearson correlation analysis, grey relation analysis (GRA) and orthogonal partial least squares discrimination analysis (OPLS-DA). Further, the antioxidant effect of KXS and its Q-makers were validated through human neuroblastoma (SH-SY5Y) cells experiment. The results showed that 103 metabolites were identified from KXS, and the similarity values between HPLC fingerprint of twelve batches of KXS were greater than 0.900. At the same time, the results of Pearson correlation analysis showed that the peaks 8, 1, 14, 17, 18, 24, 16, 21, 15, 13, 6, 5 and 3 from KXS were positively correlated with the scavenging activity values of DPPH. Combined with the results of GRA and OPLS-DA, peaks 1, 3, 5 (Sibiricose A6), 6, 13 (Ginsenoside Rg1), 15 and 24 in the fingerprints were screen out as the potential Q-makers of KXS for antioxidant effect. Besides, the results of CCK-8 assay showed that KXS and its Q-makers remarkably reduced the oxidative damage of SH-SY5Y cells caused by H2O2. However, the antioxidant activity of KXS was decreased significantly after Q-makers were knocked out. In conclusion, the metabolites in KXS were successfully identified by UPLC-Q-Exactive Orbitrap MS/MS, and the Q-makers of KXS for antioxidant effect was analyzed based on the spectrum-effect relationship. These results are beneficial to clarify the antioxidant material basis of KXS and provide the quality control standards for new KXS products development.

Natural synchrony of newborn mouse epidermal cells in vitro.

The Journal of investigative dermatology 19760501 5

Epidermal cells were separated from newborn mouse skin and grown on glass chamber slides or in plastic Petri dishes. Cell proliferation was examined at short intervals during the first 3 to 4 days in culture. DNA synthesis was estimated by the incorporation of [3H]thymidine into epidermal DNA, or by the labeling index. The mitotic rate was estimated by blocking mitotic cells with vinblastine. Reasonable agreement was found with the different methods. The cells grew synchronously with peaks of DN ...[more]

Project description:The information available in the literature concerning the beneficial effects of Dendrobium officinale flowers on the skin is limited. Therefore, the present study aimed to investigate the in vitro biological potency of its aqueous extract and screen its active components. The aqueous extract of D. officinale flowers was found to have potential antioxidant capacity (through 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), the ferric reducing ability of plasma (FRAP) and intracellular reactive oxygen species (ROS) level analyses in primary human epidermal keratinocytes), anti-cyclooxygenase2 (COX-2) effect, anti-glycation potency and anti-aging effects. A total of 34 compounds were identified using ultra-performance liquid chromatography-electrospray ionisation-quadrupole-time-of-flight-mass spectrometry (UPLC-ESI-QTOF-MS/MS). Online ABTS radical UPLC-photodiode array detection (PDA) analysis demonstrated that 1-O-caffeoyl-β-D-glucoside, vicenin-2, luteolin-6-C-β-D-xyloside-8-C-β-D-glucoside, quercetin-3-O-sophoroside, rutin, isoquercitrin and quercetin 3-O-(6''-O-malonyl)-β-D-glucoside are the major potential antioxidants. In addition, 16 components were further analysed using antioxidant assays (DPPH, ABTS and FRAP); COX-2 and advanced glycation end product (AGE) inhibitory activities were assessed. All selected compounds exerted significant ABTS radical scavenging ability and effective AGE suppressive activities. However, only certain compounds, such as rutin and isoquercitrin, displayed selective and significant antioxidant abilities, as shown by DPPH and FRAP, as well as potent COX-2 inhibitory capacity, whereas the remaining compounds displayed relatively weak or no effects. This indicates that specific components contributed to different functionalities. Our finding justified that D. officinale and its active compound targeted related enzymes and highlighted their potential application in anti-aging.

Project description:Metal-catalyzed lipid oxidation is a major factor in food waste, as it reduces shelf life. Addressing this issue, our study investigates the potential of hydrolysates derived from potato protein, a by-product of potato starch production, as metal chelating antioxidants. Through sequential en-zymatic hydrolysis using Alcalase or Trypsin combined with Flavourzyme, we produced various hydrolysates, which were then fractionated via ultrafiltration. Using a combination of peptidomics and bioinformatics, we predicted the presence of metal-chelating and free radical scavenging pep-tides across all hydrolysate fractions, with a trend indicating a higher content of antioxidant pep-tides in lower molecular weight fractions. To validate these predictions, we utilized Surface Plas-mon Resonance (SPR) and a 9-day emulsion storage experiment. While SPR demonstrated poten-tial in identifying antioxidant activity, it faced challenges in differentiating between hydrolysate fractions due to significant standard errors. In the storage experiment, all hydrolysates showed li-pid oxidation inhibition, though not as effectively as EDTA. Remarkably, one fraction (AF13) was not significantly different (p < 0.05) from EDTA in suppressing hexanal formation. These results highlight SPR and peptidomics/bioinformatics as promising yet limited methods for antioxidant screening. Importantly, this study reveals the potential of potato protein hydrolysates as antioxi-dants in food products, warranting further research. The aim of this study was to evaluate the potential of SPR as a screening technique for potato protein hydrolysates (PPH) as metal chelating antioxidants. More specifically, the goal was to correlate the KD of the hydrolysates, determined by SPR, with development of different oxidation markers obtained during a storage experiment where the PPHs were added as antioxidants to 5 % fish oil-in-water emulsions at pH 7. Additionally, the effect of using different combinations of enzymes on antioxidant activity of the hydrolysates was investigated and peptidomics was applied to characterize the composition of the hydroly-sates. With the aim of achieving shorter peptides through a high degree of hydrolysis (DH%), this study utilized sequential hydrolysis, where Trypsin (Try) or Alcalase (Alc) was paired with Flavourzyme (Fla). Owing to its broad specificity as a heterogeneous combination of various endo- and exopeptidases [20], Flavourzyme is known to facilitate high DH% and the production of short peptides [21]. However, it has been reported that when used solely with a denatured substrate protein of limited solubility, Flavourzyme can yield a significantly lower DH% than anticipated [19]. Consequently, this study was designed to include substrate pre-digestion prior to Flavourzyme addition.
