“九龙甘茶”系福建龙海地区栽培的绞股蓝(Gynostemma pentaphyllum Makino)全草为原料制成的保健冲泡饮料。本文将不同季节采收的“九龙甘茶”与日本同类饮料“甘茶蔓”进行平行比较。经14类成分系统预试,所含成分类同;其皂甙及皂甙元的高效薄层层析色谱图类同。“九龙甘茶”中的15种氨基酸及锌、铁、铜高于“甘茶蔓”,此外均基本一致。“九龙甘茶”的主成分与采收季节无明显关系。 Jiulong Gan Tea is a health-care brewed beverage made from whole plant Gynostemma pentaphyllum Makino cultivated in Longhai, Fujian. This article compares the “Jiulong Gan Tea” harvested in different seasons with the Japanese “Gancha Tea Mango” of the same kind. Pre-tested by 14 kinds of component systems, contained in the same category; its high-performance thin-layer chromatography chromatograms of saponins and saponins are similar. The 15 kinds of amino acids and zinc, iron, and copper in “Jiulong Gancha” are higher than those in “Gancha Tea”, and they are basically the same. The main component of “Kowloon Gan tea” has no obvious relationship with the harvest season.
