OBJECTIVE  To analyze the accumulation law of saponins during growth in Paris polyphylla Smith var. chinensis (Franch.) Hara, determine the content of the main saponins in different cultivation years, age groups, cultivation modes and provenances.

METHODS  The content of 5 kinds saponins(I, II, VI, VII, H) was simultaneous determined by HPLC.

RESULTS The total saponins in P. polyphylla Smith var. chinensis (Franch.) Hara were mainly composed of saponin VII and H, supplemented by saponin VI, I and II. The content of saponins(I, II, VII) was significantly different among different cultivation years rhizome, while it reached the standard of Chinese Pharmacopoeia 2020 Edition after 6 years old, 8-year-old rhizome was the highest. The saponins(I, II, VII) content in 4a rhizome and 5a rhizome was significant higher than others, and it ranged from 0.354% to 0.765% in different cultivation modes, from high to low as follows: coniferous forest>bamboo forest>broadleaf forest>greenhouse. In different provenances, it ranged from 0.592% to 0.741%, reached the highest level in Qingyuan Baikan, and was slightly lower than the standard of Chinese Pharmacopoeia 2020 Edition in Sanming Fujian.

CONCLUSION  There are remarkable correlations among saponins accumulation amounts and cultivation years, age groups, cultivation modes and provenances, which can provide reference for the artificial culvication of P. polyphylla Smith var. chinensis (Franch.) Hara.
