不同采收期黄参茎叶化学成分及生物活性变化

Variation in the Chemical Composition and Biological Activities of Sphallerocarpus gracilis Stems and Leaves among Different Harvesting Time

  • 摘要: 本文分析了不同采收期黄参茎叶(SLSG)的化学成分及生物活性变化,以期为该资源的进一步开发利用提供新信息和科学建议。结果表明对于SLSG中的大多数营养物质,其在秋季采收样品中的含量高于春季采收样品,在次年采收样品中的含量高于同年采收样品。通过体外模拟消化发现,SLSG对于大部分矿物元素有较好的释放率。SLSG对氨基酸的释放率,尤其是色氨酸、甘氨酸、脯氨酸和谷氨酸(约为6%~11%),略低于其他营养物质。L7G和A7O是SLSG中主要的酚类物质,并且在模拟血清吸收中检测出48%~55%的总酚和40%~70%的单体酚。SLSG具有良好的抗氧化能力、α-葡萄糖苷酶抑制作用及体外保肝作用。多酚类物质和氨基酸是这些生物活性功能的主要来源。采收期T4的大多数指标测定结果最优,包括Ca、Zn、Cu、Se、Na、P、酚类物质含量,抗氧化能力,α-淀粉酶及α-葡萄糖苷酶抑制作用等。上述结果加深了对SLSG化学成分及生物活性的认识,并且为该资源的进一步开发利用提供了新信息和科学建议。

     

    Abstract: Variations in the chemical composition and biological activities of a functional food Sphallerocarpus gracilis stems and leaves (SLSG) harvested at different time were investigated, so as to provide new information and scientific recommendations with the best biological activities for the further exploitation of this resource. The samples harvested in autumn in autumn showed higher contents of most nutrients than harvested in spring, and the samples harvested in the second year showed higher contents of most nutrients than harvested in the first year. Following in vitro GI digestion, SLSG showed a good release percentage for most elements; however, the release of amino acids, especially Trp, Gly, Pro and Glu, which showed a very low release percentage (approximately 6%~11%). Regarding polyphenols, L7G and A7O were the main phenolic substances in SLSG, and 48%~55% of TP and 40%~70% of the individual phenolic substances were observed in the serum fraction. SLSG showed a good antioxidant capacity, an inhibitory effect against α-glucosidase and a hepatoprotective effect in vitro. Polyphenols and amino acids were the main contributors to these biological activities. Harvesting time T4 showed the best results in most indexes, including contents of Ca, Zn, Cu, Se Na, P, polyphenols, antioxidant ability, inhibitory effects on α-amylase and α-glucosidase, etc. These results increased the understanding of the chemical composition and biological activities of SLSG and provided new information and scientific recommendations with the best biological activities for the further exploitation of this resource.
