摘要

This study focused on polysaccharides from Camellia sinensis L., a tea plant, examining their bioactivities in various clones. These tea polysaccharides (TPS) are valuable for their diverse biological functions in humans, including immunomodulatory, hypoglycemic, hypolipidemic, antitumor, and gastrointestinal benefits. Polysaccharides were extracted from different plant parts, including young meristematic leaves, stems, mature leaves, and roots, from cultivars like TRF-1, UPASI-9, and UPASI-28 in southern India. The study analyzed the morphological variations and fundamental composition of TPS across these cultivars. The purification process involved size and shape analysis using SEM, quantification of total polysaccharides through GC-MS, and quality assessment via assay methods. Additionally, bioactive compounds were characterized using FTIR spectroscopy, total phenolic content analysis, and antioxidative property assessment. This study aims to identify TPS variations among tea clones and plant organs, contributing valuable insights into their potential commercial and health benefits.
