摘　　要：考察4~9 个月移栽月龄的广西金线莲Anoectochilus roxburghii 生物学性状和多糖、多酚、黄酮含量的变化。结果表明,广西金线莲生物量随着移栽月龄的增加呈一定的增长,以移栽9 月龄最高;多糖含量的变化趋势为先下降后上升,近似“V”字形,9 月龄与4 月龄无明显差异,4 月龄含量呈现最高值;多酚和总黄酮含量均以6 月龄最高。This study investigated the biological characteristics and changes of polysaccharide, polyphenols and flavonoids of Anoectochilus roxburghii from Guangxi at four-month to nine-month plants after transplantation. Results were as follows: there was a certain increase in the biomass of A. roxburghii as the increase of transplanted month, and the biomass of nine-month after transplantation was highest. The change trend of polysaccharide content was first decreased and then increased, which was similar to the ‘V’ shape. There was no significant difference between four-month and nine-month after transplantation, and the highest polysaccharide content appeared at 4 months after transplantation. The highest contents of polyphenols and total flavonoids were appeared at 6 months after transplantation.
