This study explores the traditional knowledge of plants used by traditional health practitioners (THPs) in the treatment of symptoms or syndromes related to mental illnesses in the district of Bamako in Mali, along with the identification of affiliated traditional treating methods. An exploratory and cross-sectional ethnopharmacological survey was conducted in the district of Bamako. The Malian Federation of Associations of Therapists and Herbalists (FEMATH) assisted in the identification and inclusion of the THPs.

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.

One purified neutral polysaccharide fraction was obtained from the rhizome of by DEAE ion exchange and gel chromatography. Structure elucidation was performed by methanolysis, methylation, FT-IR, and NMR. The results indicated that PSP-NP was composed of 1,4-β-D-Gal,1, 4, 6-β-D-Gal, T-α-D-Man,1, 4-α-D-Glc, and T-α-D-Glc with a molecular weight of 43.

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.

Article Synopsis
  • - The leaf polysaccharide (NNLP) was successfully isolated and purified, resulting in a fraction (NNLP-I-I) with a molecular weight of 16.4 kDa, identified as a pectic polysaccharide.
  • - Structural analysis via NMR showed that NNLP-I-I has a backbone primarily made of homogalacturonan, with a combination of short rhamnogalacturonan I and various side chains.
  • - Biological tests indicated that NNLP-I-I has antioxidant properties, enhancing the intestinal cellular defense against oxidative stress, which can benefit aged mice by improving their intestinal function.

Article Synopsis
  • Two pectic polysaccharides, CPP-1 and CTP-1, were extracted from the roots of Codonopsis pilosula and Codonopsis tangshen using boiling water and chromatography.
  • Both polysaccharides share a similar backbone structure but differ in molecular weight and composition, which affects their antioxidant properties.
  • The study suggests that CPP-1 and CTP-1 have potential as natural antioxidants, highlighting their value for future health product developments.

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.

Silver linden flowers contain different pectins (PSI-PSIII) with immunomodulating properties. PSI is a low-esterified pectic polysaccharide with predominant homogalacturonan region, followed by rhamnogalacturonan I (RGI) with arabinogalactan II and RGII (traces) domains. PSII and PSIII are unusual glucuronidated RGI polymers.
