[PMID: 38710561 DOI: 10.1016/j.carbpol.2024.122171] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2024] [Revised: 03/22/2024] [Accepted: 04/15/2024] [Indexed: 05/08/2024]
Abstract
Commercially available mushroom polysaccharides have found widespread use as adjuvant tumor treatments. However, the bioactivity of polysaccharides in Lactarius hatsudake Tanaka (L. hatsudake), a mushroom with both edible and medicinal uses, remains relatively unexplored. To address this gap, five L. hatsudake polysaccharides with varying molecular weights were isolated, named LHP-1 (898 kDa), LHP-2 (677 kDa), LHP-3 (385 kDa), LHP-4 (20 kDa), and LHP-5 (4.9 kDa). Gas chromatography-mass spectrometry, nuclear magnetic resonance, and atomic force microscopy, etc., were employed to determine their structural characteristics. The results confirmed that spherical aggregates with amorphous flexible fiber chains dominated the conformation of the LHP. LHP-1 and LHP-2 were identified as glucans with α-(1,4)-Glcp as the main chain; LHP-3 and LHP-4 were classified as galactans with varying molecular weights but with α-(1,6)-Galp as the main chain; LHP-5 was a glucan with β-(1,3)-Glcp as the main chain and β-(1,6)-Glcp connecting to the side chains. Significant differences were observed in inhibiting tumor cell cytotoxicity and the antioxidant activity of the LHPs, with LHP-5 and LHP-4 identified as the principal bioactive components. These findings provide a theoretical foundation for the valuable use of L. hatsudake and emphasize the potential application of LHPs in therapeutic tumor treatments.

[PMID: 38909825 DOI: 10.1016/j.jep.2024.118481] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/06/2024] [Revised: 05/14/2024] [Accepted: 06/20/2024] [Indexed: 06/25/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Potentilla Anserina Linnaeus, a traditional Chinese herb with ethnic characteristics, is considered a superior material by the people of Qinghai and Tibet. Traditionally, it has been used to invigorate the spleen, quench thirst, tonify the blood, astringing to stop bleeding, and relieve diarrhea. This is the reason for its frequent usage in treating spleen deficiency, diarrhea, and various bleeding disorders. At the same time, P. anserina is often consumed as food by the Tibetan people to obtain nourishment and health benefits. AIM OF THE REVIEW The present review provides a systematic description of P. anserina, covering its botany, ethnopharmacology, phytochemical constituents, and various pharmacological activities of extracts. This overview aims to provide insights into research directions and potential applications of P. anserina. MATERIALS AND METHODS Information on P. anserina was gathered through various sources, including Google Scholar, PubMed, Elsevier, CNKI, and Web of Science. In addition, information was available from native texts and prominent ethnopharmacologists. RESULTS So far, 154 different chemical substances have been isolated and identified from P. anserina, with tannins, flavonoids, and triterpenes accounting for the majority. Polysaccharides and triterpenes are the main material components responsible for the pharmacological activity of P. anserina. Research shows that P. anserina exhibits rich pharmacological activities, including antioxidant, antiviral, blood tonic, immune regulation, cardiovascular system treatment, diabetes treatment, and liver protection. CONCLUSIONS Some traditional applications of P. anserina have been confirmed. However, due to incomplete evaluation indicators and other reasons, further in vitro and in vivo studies are needed to clarify its pharmacological evaluation, which remains a focus of future research. Additionally, we recommend that future studies concentrate on the quality control and safety evaluation of P. anserina to address research gaps and offer theoretical support for the plant's potential functions and clinical applications.

Abstract
INTRODUCTION The traditional Chinese medicine (TCM) Potentilla anserina L. can use both as food and medicine. At present, the market mainly depends on experience to identify the species and determine the production areas of P. anserina. To ensure the quality of P. anserina, it is essential to improve the level of quality control. OBJECTIVE We aimed to establish a rapid and nondestructive discrimination model to identify P. anserina from different production areas by near-infrared spectroscopy. METHODS The spectra of complete P. anserina medicinal materials and their powder of the same variety from four production areas were collected, and principal component analysis discriminant analysis and partial least squares discriminant analysis (PLS-DA) were conducted based on different pretreatment methods and band selection methods. Then, the spectra of complete medicinal materials were converted into the spectra of medicinal powder for nondestructive identification. RESULTS The correct recognition rate (CRR) of the PLS-DA discriminant model was the best after spectral preprocessing using autoscaling and competitive adaptive reweighted sampling for band selection. The CRRs of the calibration set and validation set were 100%, the CRRs of the external test set were 95%, 90%, 82%, and 88%, respectively, and the CRRs of the transfer external test set were 84%, 80%, 82%, and 86%, respectively. CONCLUSION We realized the nondestructive and effective identification of P. anserina from different origins and laid a foundation for the industrialization and upgrading of TCM.

Antioxidant capacity of xylooligosaccharides generated from beechwood xylan by recombinant family GH10 Aspergillus niger xylanase A and insights into the enzyme's competitive inhibition by riceXIP. Enzyme Microb Technol 2024; 179:110456. [PMID: 38754147 DOI: 10.1016/j.enzmictec.2024.110456] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/29/2024] [Revised: 04/21/2024] [Accepted: 05/08/2024] [Indexed: 05/18/2024]
Abstract
In this study, the family GH10 xylanase AnXylA10 derived from Aspergillus niger JL15 strain was expressed in Pichia pastoris X33. The recombinant xylanase, reAnXylA10 exhibited optimal activity at 40 ℃ and pH 5.0. The hydrolysates generated from beechwood xylan using reAnXylA10 primarily consisted of xylobiose (X2) to xylohexaose (X6) and demonstrated remarkable antioxidant capacity. Furthermore, the rice xylanase inhibitory protein (riceXIP) was observed to competitively inhibit reAnXylA10, exhibiting an inhibition constant (Ki) of 140.6 nM. Molecular dynamics (MD) simulations of AnXylA10-riceXIP complex revealed that the α-7 helix (Q225-S238) of riceXIP intruded into the catalytic pocket of AnXylA10, thereby obstructing substrate access to the active site. Specifically, residue K226 of riceXIP formed robust interactions with E136 and E242, the two catalytic sites of AnXylA10, predominantly through high-occupied hydrogen bonds. Based on QTAIM, electron densities for the atom pairs K226riceXIP@HZ1-E136AnXylA10@OE2 and K226riceXIP@HZ3-E242AnXylA10@OE1 were determined to be 0.04628 and 0.02914 a.u., respectively. Binding free energy of AnXylA10-riceXIP complex was -59.0±7.6 kcal/mol, significantly driven by electrostatic and van der Waals forces. Gaining insights into the interaction between xylanase and its inhibitors, and mining the inhibition mechanism in depth, will facilitate the design of innovative GH10 family xylanases that are both highly efficient and resistant to inhibitors.
