Abstract:

The biomass and active ingredients of four cultivars (‘Sanming NL (narrow leaf)’, ‘Sanming RL (round leaf)’, ‘Zhangzhou NL’ and ‘Taiwan AF’) of Anoectochilus roxburghii and Anoectochilus formosanus from different geographical sources were assayed 120 days after transplantation. The polysaccharides content, fresh weight and dry weight per plant of ‘Zhangzhou NL’ were significantly higher than that of the other three cultivars. Also, the total polyphenols and total flavonoids content of ‘Taiwan AF’ were significantly higher than that of the other three cultivars. The dynamic changes of the active ingredients in different collection periods were investigated. Except for ‘Taiwan AF’ cultivar, the variation rules of total polyphenols, total flavonoids and polysaccharides content in the three varieties were roughly the same. The content of total polyphenols and total flavonoids increased and the content of polysaccharides decreased with the extension of transplanting time. The content of total polyphenols and total flavonoids reached the maximum 150 days after transplantation for ‘Sanming NL’ and ‘Sanming RL’. For ‘Sanming NL’, the content of total polyphenols and total flavonoids was (9.81±0.24) and (4.62±0.16) mg/g, respectively. For ‘Sanming RL’, the content of total polyphenols and total flavonoids were (9.27±0.22) and (4.60±0.17) mg/g, respectively. In ‘Zhangzhou RL’, the content of total polyphenols and total flavonoids reached the maximum 120 days after transplantation. The content of total polyphenols and total flavonoids in ‘Zhangzhou RL’ was (7.74±0.05) and (4.63±0.04) mg/g, respectively. The content of polysaccharides reached the maximum 90, 0 and 120 days after transplantation for ‘Sanming NL’, ‘Sanming RL’ and ‘Zhangzhou RL’, respectively. The content of polysaccharides was (26.05±2.11), (24.29±2.33) and (45.90±4.70) mg/g in ‘Sanming NL’, ‘Sanming RL’ and ‘Zhangzhou RL’, respectively. Besides, the analysis of the active components in different parts in the plant of ‘Sanming NL’ and ‘Sanming RL’ revealed that polyphenols and flavonoids were mainly accumulated in the leaves but sugars in the stems.
