摘要: 本研究测定了永州野生绞股蓝中活性物质与稀土元素的含量,并探究了它们在持续煮沸与沸水冲泡两种方式下的释出规律,为永州野生绞股蓝的开发及人们日常保健提供参考。结果发现,(1)所有元素种类的含量极低,其中Sc、Pm、Tm、Lu未被检出,另13种元素含量Ce>La>Nd>Eu>Y>Sm>Gd>Pr>Dy>Er>Tb>Yb>Ho,所有稀土元素的总含量为0.1377 mg/Kg;沸水处理下,各元素在持续煮沸方式释出量均较自然冷却方式高,两种方式下总释放量分别为0.0223与0.0414 mg/Kg。(2)皂苷、黄酮、多糖含量分别为20.8、28.1、52.5 mg/g。三种活性物质在沸水处理下均有释出,且释出量随时间增加呈逐渐增加趋势,但在自然冷却和持续煮沸两种不同方式下,各活性物质的释出规律差异明显。两种方式下三者释出总量分别为26.12与48.94 mg/g。(3)在沸水处理的两种方式下,三种活性物质的释出量间均表现出显著正相关(P<0.01)。结果表明,永州野生绞股蓝活性物质含量较高,且在沸水中释出明显,且稀土元素的含量及其在沸水中的释出量极低,不会对人体健康产生毒害效应,因此具有显著的保健价值。

Abstract: In this study,the content of rare earth elements(REE) and active substances in wild Gynostemma pentaphyllum of Yongzhou and their releasing law in hot water by two ways of continuous boiling and natural cooling were analyzed to provide references for its comprehensive development and daily health care applications.Results showed that,(1) All REE content were extremely low and Sc,Pm,Tm and Lu even could not be detected.Content order of other 13 elements was Ce>La>Nd>Eu>Y>Sm>Gd>Pr>Dy>Er>Tb>Yb>Ho.Total content of all REE was 0.1377 mg/Kg.REE released more in continuous boiling way than in natural cooling way,total release amount in the two ways were 0.0414 and 0.0223 mg/Kg,respectively.(2) The content of saponins,flavonoids and polysaccharide in wild G.pentaphyllum of Yongzhou were 20.8,28.1 and 52.5 mg/g,respectively.All the three kinds of active substances showed a significant releasing in boiling water,and the total releasing content of three kinds of active substances in two ways was 26.12 and 48.94 mg/g,respectively.However,they showed different releasing rule in two treating ways of natural cooling and continuous boiling.(3) There were a significant positive correlation among the releasing content of three active substances (P<0.01).Results indicated that,wild G.pentaphyllum of Yongzhou showed a great value for further development and utilization for the high content and remarkable releasing in boiling water of active substances.Meanwhile,the content of REE and its releasing amount in boiling water was extremely few.

Key words: rare earth elements;active substances;release law, Gynostemma pentaphyllum
