Effect of Different Interplanting Mode on Main Components from Rhizome of Polygonatum cyrtonema

In March 2021, rhizome segments of Polygonatum cyrtonema were interplanted in 5 sample plots under Camellia oleifera stand, Torreya grandis ‘Merrillii’ and Phyllostachys edulis forest in Longquan, Zhejiang province. In April 2022, rhizomes from different sample plots were harvested and determinations were carried out on contents of polysaccharide, protein, flavone, crude fat, and 9 mineral elements. The results showed that the content of polysaccharide and protein from rhizome under C. oleifera was the highest, 97.50?6.41mg/g and 12.40?0.42 g/100g respectively. The crude fat content from that under T. grandis ‘Merrillii’ forest was the highest, up to 6.10?0.38 mg/g. The content of flavonoids from that under Ph. edulis was the highest, up to 7.22?0.77 mg/g. There was a wide variation in the content of the nine mineral elements in rhizomes from the five sample plots.
