Comparative analysis of antioxidant activity and structural changes of <i>Gastrodiae Rhizoma</i> polysaccharides between sulfur-fumigation and nonsulfur-fumigation.

ABSTRACT:

Introduction

Gastrodiae Rhizoma (referred to Tianma in Chinese), the dried tuber of Gastrodia elata Bl. (Orchidaceae), is utilized as a medicine-food homology product. Sulfur fumigation is commonly employed in the processing of Gastrodiae Rhizoma (GR). Polysaccharides are a crucial active substance produced in GR, yet the impacts of sulfur fumigation on them remain unelucidated.

Methods

This study aimed to optimize the hot water extraction conditions of polysaccharides from sulfur-fumigated GR (SGCPs) and nonsulfur-fumigated GR (NGCPs). The research explored the effects of sulfur fumigation on the structure and antioxidant activity of GR polysaccharides.

Results and discussion

The results showed that the optimal extraction conditions for SGCPs and
