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.

Background: Aconitum carmichaelii is an industrially cultivated medicinal plant in China and its lateral and mother roots are used in traditional Chinese medicine due to the presence of alkaloids. However, the rootlets and aerial parts are discarded after collection of the roots, and the non-toxic polysaccharides in this plant have attracted less attention than the alkaloids and poisonous features. In this study, five neutral and 14 acidic polysaccharide fractions were isolated systematically from different plant parts of A.

Aging is a biological process of progressive deterioration of physiological functions, which poses a serious threat to individual health and a heavy burden on public health systems. As population aging continues, research into anti-aging drugs that prolong life and improve health is of particular importance. In this study, the polysaccharide from stems and leaves of was obtained with water extraction and alcohol precipitation, and then separated and purified with DEAE anion exchange chromatography and gel filtration to obtain CVP-AP-I.

The industrial processing of Aconitum carmichaelii roots for use in Traditional Chinese Medicine generates a high amount of waste material, especially leaves. An acidic polysaccharide fraction isolated from these unutilized leaves, AL-I, was in our previous work shown to contain pectic polysaccharides. This study aimed to investigate the protective effect of AL-I on ulcerative colitis for the possible application of A.

Roots of Aconitum carmichaelii are used in Asian countries due to its content of bioactive alkaloids. In the production of root preparations, tons of leaves are usually discarded, leading to a huge waste of herbal material. The aim of this study is to investigate the polysaccharides in these unutilized leaves.

Ethnopharmacological Relevance: The root of Angelica sinensis, has been commonly used in gynecology for centuries, and is normally applied divided into different parts in various clinical applications. At present, the majority of existing studies focus on the volatile oil and ferulic acid extracted from different parts of A. sinensis, but there is a dearth of scientific information on its water-soluble polysaccharides.

Ethnopharmacological Relevance: Aconitum carmichaelii, belonging to the Ranunculaceae family, is a widely used traditional herbal plant in Asian countries, especially in China. The lateral ("Fuzi") and mother ("Chuanwu") roots are the two main plant parts used in Traditional Chinese Medicine (TCM), where they are used in the treatment of acute myocardial infarction, heart failure, rheumatoid arthritis, and as analgesics.

Aim Of The Study: In order to further guide the research direction and application of A.

An inulin (CPPF), isolated from a traditional Chinese herbal medicine , was characterized and demonstrated with potential prebiotic activity before. Based on its non-digested feature, the intestinal mucosa and microbiota modulatory effects on immunosuppressed mice were investigated after oral administration of 200, 100 and 50 mg/kg of CPPF for 7 days. It was demonstrated that the secretions of sIgA and mucin 2 (Muc2) in ileum were improved by CPPF, and the anti-inflammatory activities in different intestine parts were revealed.

Article Synopsis
  • * PGP-I-I is primarily composed of 1,5-α-L-arabinan, and includes arabinogalactan chains linked to a rhamnogalacturonan I backbone, which is further connected to longer galacturonan chains.
  • * In vitro studies indicate that PGP-I-I enhances intestinal cellular antioxidant defenses under hydrogen peroxide stress by increasing the expression of antioxidant genes, thereby mitigating oxidative damage.

Article Synopsis
  • Codonopsis pilosula and C. tangshen are two traditional Chinese medicinal plants, primarily known for their active polysaccharides, which were characterized in this study.
  • The study confirmed that the neutral polysaccharide fractions (CPPN and CTPN) are inulin-type fructans with different degrees of polymerization, affecting their biological activities.
  • Results showed that CPPN and CTPN enhance antioxidant defenses and promote the growth of beneficial Lactobacillus bacteria, indicating their potential as sources for intestinal health applications.

We have carried out the investigation on a sponge-derived fungus,which was identified as Emericella variecolor from the south sea of China. Two new chemical constituents,(+)-2-acetyl-dihydroterrein (1) and (+)-3-acetyl-dihydroterrein (2),with four known compounds,anditomin (3),andilesin A (4),andilesin C (5) and andilesin B (6),were isolated from this fungus by column chromatography over silica gel, Sephadex LH-20, and ODS. The structures of 1 and 2 were elucidated by spectroscopic methods including NMR,HR-ESI-MS,and CD.

Two polysaccharides, GCP-I-I and GCP-II-I, were obtained from 100°C water extracts of Gentiana crassicaulis roots by DEAE anion exchange chromatography and gel filtration. The results from methanolysis, methylation, FT-IR and NMR, indicated that these two fractions are typical pectic polysaccharides, with HG and RG-I regions and AG-I/AG-II side chains, and some of the galacturonic acid units of fraction GCP-I-I were methyl esterified. Fractions GCP-I-I and GCP-II-I, both exhibited potent complement fixation, and fraction GCP-I-I was more potent than positive control BPII.
