Abstract
Authentication of Chinese medicine materials in prescriptions is extremely difficult due to the complicated chemical matrix. A strategy integrating in-depth profiling, chemical marker selection, and selected detection was established and exemplarily applied to authenticate paeony root in ShaoYao-GanCao decoction. First, an ultra-performance liquid chromatography/linear trap quadrupole-Orbitrap method was developed to probe the chemical compositions of the decoction. Second, 20 batches of decoctions prepared from white paeony root and red paeony root were compared by a metabolomics method, and multistep chemometrics analysis distinguished the chemical markers. Third, an ultra-performance liquid chromatography/QDa-selected ion monitoring method was developed to authenticate the paeony root in decoctions. As a result, 161 compounds were characterized, including 84 triterpene saponins, 42 flavonoids, and 10 monoterpenes. Four chemical markers and paeoniflorin were successfully screened out as chemical markers for white paeony root. The selected ion monitoring method easily differentiated authentic decoction (prepared from white paeony root) from fraud decoction (prepared from red paeony root) by monitoring the above five chemical markers. In conclusion, the strategy was proved effective in authentication of paeony root in ShaoYao-GanCao decoction, and it can also be applied to authenticate other Chinese medicine materials in prescriptions, which will greatly avail the quality enhancement of prescriptions.

The Protective Effects of Orthosiphon stamineus Extract Against Intestinal Barrier Injury in High-Fat Diet-Induced Mouse and Oxidative Stress Cell Models. Nat Prod Commun 2021. [DOI: 10.1177/1934578x20985346] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 01/27/2023] Open
Abstract
Orthosiphon stamineus Benth. (Lamiaceae) is commonly used for the treatment of kidney diseases, but its role in intestinal barrier function remains unknown. The present study investigated the protective effects of O. stamineus extract (OE) against oxidative stress-induced injury to the small intestinal epithelium and the possible mechanism. High-performance liquid chromatography fingerprinting was used to analyze OE. Oxidative stress was induced by hydrogen peroxide (1 mM for 1 hour) in an IPEC-J2 cell monolayer model and a high-fat diet in C57BL/6 mice (8 weeks). The malondialdehyde (MDA) content was tested in both models. To evaluate permeability, transepithelial electrical resistance (TEER) was tested in a cell model. Serum diamine oxidase (DAO) and endotoxin contents were determined in a mouse model, and histological sections were analyzed. The messenger ribonucleic acid expression of tight junction proteins was measured by quantitative real-time polymerase chain reaction. Pretreatment with OE (50 µg/mL) increased the IPEC-J2 cell monolayer TEER (12.4%) and decreased MDA (from 6.1 to 4.7 mmol/mg prot). Oral administration of OE (100 mg/kg) decreased serum DAO (34.2%), endotoxin (13.4%), and MDA (from 21.3 to 11.0 mmol/mL) in mice. OE upregulated ZO-1 (42.8% in the cell model and 125.0% in mice) and occluding (127.0% in the cell model and 120.3% in mice) gene expression. These results confirmed the protective effect of OE on the intestinal barrier, which was associated with the antioxidant effect of OE; thus, OE is suitable for the prevention and treatment of intestinal barrier injury.

Genotype selection for phytochemical content and pharmacological activities in ethanol extracts of fifteen types of Orthosiphon aristatus (Blume) Miq. leaves using chemometric analysis. Sci Rep 2020; 10:20945. [PMID: 33262368 PMCID: PMC7708627 DOI: 10.1038/s41598-020-77991-2] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2020] [Accepted: 11/18/2020] [Indexed: 11/30/2022] Open
Abstract
Orthosiphon aristatus (Blume) Miq. of the Lamiaceae family, called as kumis kucing in Indonesia, is a valuable medicinal plant for their pharmacological properties. The present study comprised of fifteen genotypes of O. aristatus was undertaken to evaluate the genotypes based on phytochemical content and pharmacological activities of leaves ethanol extract. Chemometric analysis (correlation and principal component analysis) was also used to investigate the genetic variability based on phytochemical content and pharmacological activities of O. aristatus genotypes. Results of phytochemical characterization showed that total phenolic ranged from 1.48 to 36.08 (maximum in A15) mg GAE/g DW, total flavonoid ranged from 0.10 to 3.07 (maximum in A15) mg QE/g DW, sinensetin ranged from 0.36 to 4.02 (maximum in A11) mg/g DW, and rosmarinic acid ranged 0.06 to 7.25 (maximum in A7) mg/g DW. Antioxidant activity was tested using DPPH and FRAP assay. Antioxidant results showed that DPPH ranged from 1.68 to 15.55 (maximum in A15) μmol TE/g DW and FRAP ranged from 0.07 to 1.60 (maximum in A1 and A7) μmol TE/g DW. The genotype A8 showed the highest cytotoxic activities against HeLa (66.25%) and MCF-7 (61.79%) cell lines. Maximum α-glucosidase inhibitory activity was recorded in genotype A2 with the value of 62.84%. The genotypes A1, A2, A7, A11, and A15 were identified as superior based on their phytochemicals content and pharmacological activities coupled with chemometric analysis. This finding is important for breeding studies and also the pharmaceutical perspective of O. aristatus.
