Bamboo has a noticeable gradient anatomical pattern, with an increasing proportion of vascular bundles from IB to OB and a gradual decrease in the proportion of parenchyma tissues. In terms of chemical composition, the ash, extractives and acid-soluble lignin content gradually decrease from IB to OB. The holocellulose content follows the trend: IB (62.8%)\u2009&lt;\u2009OB (65.9%)\u2009&lt;\u2009MB (66.3%) while the acid-insoluble lignin content exhibits the opposite trend: IB (22.6%)\u2009&gt;\u2009OB (17.8%)\u2009&gt;\u2009MB (17.7%). Pyrolysis products reveal the diversity of carbohydrates and lignin derivatives, with a lignin monomeric composition rich in syringyl and guaiacyl units and lower amounts of H-units: IB has a H:G:S relation of 18:26:55, MB has 15:27:58 and OB 15:40:45; S\/G ratio values were respectively 1.22, 1.46 and 0.99. A comprehensive analysis highlights significant gradient variations in the structure and chemistry of bamboo, providing robust support for the classification and refinement methods of bamboo residues for potential applications.<\/p>","DOI":"10.21203\/rs.3.rs-4372670\/v1","type":"posted-content","created":{"date-parts":[[2024,5,10]],"date-time":"2024-05-10T04:29:56Z","timestamp":1715315396000},"source":"Crossref","is-referenced-by-count":0,"title":["Structural and Chemical Analysis of three regions in Bamboo (Phyllostachys edulis)"],"prefix":"10.21203","author":[{"given":"Shaohua","family":"Gua","sequence":"first","affiliation":[{"name":"International Center for Bamboo and Rattan"}]},{"given":"Ana","family":"Louren\u00e7o","sequence":"additional","affiliation":[{"name":"Universidade de Lisboa"}]},{"given":"Jorge","family":"Gominho","sequence":"additional","affiliation":[{"name":"Universidade de Lisboa"}]},{"given":"Ge","family":"Wang","sequence":"additional","affiliation":[{"name":"International Center for Bamboo and Rattan"}]},{"given":"Haitao","family":"Cheng","sequence":"additional","affiliation":[{"name":"International Center for Bamboo and Rattan"}]}],"member":"8761","reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"100070","DOI":"10.1016\/j.bamboo.2024.100070","article-title":"Investigation and application of different extraction techniques for the production of finer bamboo fibres","volume":"7","author":"Asmare FW","year":"2024","unstructured":"Asmare FW, Liu X, Qiao G, Li R, Babu MK, Wu D (2024) Investigation and application of different extraction techniques for the production of finer bamboo fibres.
