Abstract:

The stems and leaves growing on the ground of Paris polyphylla var. yunnanensis were sampled from August to November to analysis composition and assess yields in the main planting area Wuding, Yunlong and Maguan County in Yunnan province. The yield of stems and leaves is about 900.0 kg/m2. Saponins content in stems and leaves were equivalent to that in underground rhizome. The main saponins components of underground rhizome were PolyphyllaⅡand Ⅶ, did not contain Polyphylla H and PA, which was the same to the saponins content of underground rhizome and had the same control effect. If stems and leaves were used as medicines, the production value could increase 27000 yuan per hectare. The stems and leaves from the blossom plants have higher saponins content than seedlings. The peels of fruits have similar composition to the traditional medicine part underground stems. The stems and leaves growing on the ground of Paris polyphylla var. yunnanensis could be used as medicines and significantly improved planting benefits.
