Water‐soluble polysaccharides (WSP) were secluded from Tamarindus indica (TWSP) and Pithecellobium dulce (PWSP) seeds by hot water method. The physico‐chemical properties revealed that the polysaccharides might be used as a potential food additive. The micrometric properties of TWSP and PWSP possessed a bulk density of 0.64 and 0.68 g/ml, respectively. The isolated polysaccharides were subjected to Fourier transform infrared spectroscopy and Nuclear magnetic resonance spectroscopy for its compositional analysis and exhibited that both the isolates are heteropolysaccharides. The spectra of both the mucilages were resonating at δ 3.00–δ 5.00 ppm which confirmed the presence of polysaccharides. Thermo gravimetric analysis showed that the isolated polysaccharides were thermally stable. Scanning electron microscopy and X‐ray diffraction depicted the morphological characteristics. The radical scavenging ability and antibacterial activity proved that the polysaccharides can be explored as a functional food ingredient. Furthermore, the prebiotic potential of polysaccharides stimulated the growth of Lactobacillus delbrueckii and Lactobacillus fermentum over inulin. PRACTICAL APPLICATIONS: The study provides optimum extraction conditions to obtain TWSP and PWSP seeds using response surface methodology. The isolated polysaccharides can be used as therapeutic agent and as a food additive due to its high purity obtained from Fourier transform infrared spectroscopy and Nuclear magnetic resonance spectroscopic analysis. The excellent flowability and compressibility of polysaccharides can be applied in pharmaceutical formulation as an excipient. The active component present in the isolated polysaccharides can be used as a food preservative. The supplement of TWSP and PWSP as a carbon source accelerated the growth of probiotics which could be used as natural prebiotics. Thus the study concluded that the water‐soluble polysaccharide obtained from the agro‐industrial by product has the wide application in food and pharmaceutical industries.

罗望子和木瓜种子水溶性多糖的提取与表征
通过热水法从罗望子 (TWSP) 和 Pithecellobium dulce (PWSP) 种子中分离出水溶性多糖 (WSP)。理化性质表明多糖可用作潜在的食品添加剂。TWSP 和 PWSP 的测微特性分别具有 0.64 和 0.68 g/ml 的堆积密度。对分离得到的多糖进行傅里叶变换红外光谱和核磁共振光谱分析，结果表明分离物均为杂多糖。两种粘液的光谱都在 δ 3.00–δ 5.00 ppm 共振，这证实了多糖的存在。热重分析表明分离的多糖是热稳定的。扫描电子显微镜和 X 射线衍射描绘了形态特征。自由基清除能力和抗菌活性证明多糖可以作为功能性食品成分进行探索。此外，多糖的益生元潜力刺激了德氏乳杆菌和发酵乳杆菌在菊粉上的生长。实际应用：该研究提供了使用响应面方法获得 TWSP 和 PWSP 种子的最佳提取条件。分离的多糖由于其从傅里叶变换红外光谱和核磁共振光谱分析中获得的高纯度而可用作治疗剂和食品添加剂。多糖优异的流动性和可压缩性可作为赋形剂应用于药物制剂中。分离出的多糖中存在的活性成分可用作食品防腐剂。TWSP 和 PWSP 作为碳源的补充加速了可用作天然益生元的益生菌的生长。因此研究得出结论，从农工副产品中提取的水溶性多糖在食品和制药行业具有广泛的应用。
