Abstract

This research investigates the extraction, quantification and characterisation of tannin from the bark of Neltuma juliflora (Sw.) Raf. (N. juliflora, formerly known as Prosopis juliflora (Sw.) DC.), an invasive species that is widely available but underutilised. Various solvent extraction techniques, including single-phase, combined and sequential extractions, were evaluated. The highest tannin yield (85%) was obtained with 4% NaOH in single-phase extraction, while combined extraction resulted in the highest tannin purity (85.91%). Sequential extraction demonstrated solvent selectivity, with methanol producing the highest extract (93.6%) and acetone yielding a highly purified fraction (83.14%). The presence of essential tannin functional groups was validated by Fourier Transform Infra-red (FTIR) spectroscopy. The analysis of band gap energy indicated values between 4.00 and 5.09 eV, varying with the extraction method. These findings underscore N. juliflora as a promising sustainable tannin source, which offers an eco-friendly alternative to conventional sources and supports invasive species control efforts.

多溶剂提取，定量和表征单宁从木犀草树皮：途径可持续利用。

本研究对Neltuma juliflora （Sw.）树皮中单宁的提取、定量和表征进行了研究。英国皇家空军。（N. juliflora，原名Prosopis juliflora， Sw.）)，一种广泛存在但未被充分利用的入侵物种。对各种溶剂萃取技术进行了评价，包括单相萃取、联合萃取和顺序萃取。在4% NaOH条件下，单宁收率最高（85%），联合萃取单宁纯度最高（85.91%）。顺序萃取证明了溶剂选择性，甲醇萃取率最高（93.6%），丙酮萃取率最高（83.14%）。傅里叶变换红外光谱（FTIR）证实了单宁必需官能团的存在。带隙能的分析值在4.00 ~ 5.09 eV之间，随提取方法的不同而变化。这些发现强调了N. juliflora是一种有前途的可持续单宁来源，它提供了传统来源的环保替代品，并支持入侵物种控制工作。

期刊介绍： The aim of Natural Product Research is to publish important contributions in the field of natural product chemistry. The journal covers all aspects of research in the chemistry and biochemistry of naturally occurring compounds. The communications include coverage of work on natural substances of land and sea and of plants, microbes and animals. Discussions of structure elucidation, synthesis and experimental biosynthesis of natural products as well as developments of methods in these areas are welcomed in the journal. Finally, research papers in fields on the chemistry-biology boundary, eg. fermentation chemistry, plant tissue culture investigations etc., are accepted into the journal. Natural Product Research issues will be subtitled either ""Part A - Synthesis and Structure"" or ""Part B - Bioactive Natural Products"". for details on this , see the forthcoming articles section. All manuscript submissions are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. All peer review is single blind and submission is online via ScholarOne Manuscripts.
