Chemical characterization and comparative analysis of different parts of through UHPLC-Q-TOF-MS.

(L.) DC. () is a medicinal herb valued for its dried roots with anti-inflammatory, analgesic, diuretic, and other therapeutic properties.

Ultrasonic-assisted extraction of polysaccharide from Paeoniae Radix alba: Extraction optimization, structural characterization and antioxidant mechanism in vitro.

Paeoniae Radix alba is used in Traditional Chinese Medicine for the treatment of gastrointestinal disorders, immunomodulatory, cancer, and other diseases. In the current study, the yield of Paeoniae Radix alba polysaccharide (PRP) was significantly increased with optimal ultrasound-assisted extraction compared to hot water extraction. Further, an acidic polysaccharide (PRP-AP) was isolated from PRP after chromatographic separation and was characterized as a typical pectic polysaccharide with side chains of arabinogalactans types I and II.

Characterization and prebiotic activity in vitro of inulin-type fructan from Codonopsis pilosula roots.

The inulin-type fructan was obtained by DEAE anion exchange chromatography from C. pilosula Nannf. var.

[Study on Quality Evaluation of Ophiopogonis Radix in Sichuan].

Objective: To evaluate the quality of Ophiopogonis Radix from produce area, circulation link and clinical application in Sichuan, and to provide the theoretical basis for the quality control of Ophiopogonis Radix in Sichuan.

Methods: 105 samples were collected from different produce area, market, factory of decoction pieces, drugstore in Sichuan. The content of moisture,total ash, extractum, total saponin, heavy metal, harmful element, pesticide residues, sulfur dioxide were measured by the methods which recorded in Chinese pharmacopoeia.

[HPLC simultaneous determination of contents of 5 saponin constituents in Ophiopogonis Radix].

This research is to establish an HPLC method for the simultaneous determination of ophiopogonin D, ophiopogonin D', ophiopogonin C, deacetylophiopojaponin A and ophiogenin-3-O-α-L-rhamnosyl-(1-->2)-β-D-glucoside in Ophiopogonis Radix. HPLC-ELSD analysis was performed on a Kromasil 100-5 C₁₈ column (4.6 mm x 250 mm, 5 µm), with the mobile phase of acetonitrile (A) -water (B) in gradient elution mode (0-45 min, 35%-55% A), at a flow rate of 1 mL · min⁻¹.

[Effects of Different Terrain Farmland on Codonopsis pilosula Growth in Loess Plateau Dry Areas].

Objective: To study the effects of different terrain farmland on Codonopsis pilosula growth in arid regions, and then to provide basis for choosing appropriate terrain for Codonopsis pilosula cultivation in the northwest region.

Methods: Based on the observation of field production,plot cultivation experiment was designed to observe and record the effects of different terrain farmland on Codonopsis pilosula growth period and yeild, and to analyze the terrain effects on Codonopsis pilosula production comprehensively.

Results: There were no significant differences between field production and plot cultivation experiment.
