The application discloses a new compound in Pteris wallichiana and an extraction, separation and purification method and application of the new compound. The compound is wallichiana A, 2,3-dihydro-2-[(beta-D-xylosyl) methyl]-5,7-dimethyl-6-(2-chloroethyl)-2(S)-1H-inden-1-one (wallichiana B), which is obtained through extraction and crude separation of medicinal materials, separation and purification of an ethyl acetate part. The compounds obtained through the separation and purification are subjected to anti-tumor activity screening experiments, and the results show that the two compounds have half-inhibition activity on in-vitro tumor growth of breast cancer MCF-7, colon cancer HCT-116, cervical cancer Hela and lung cancer A549, and can be used for treating anti-tumor diseases, and provide a reference for continuing to strengthen the chemical component and activity screening research of the plant and the research on structure modification of the compounds with good activity in the plant.

The utility model discloses a gynura divaricata floating cultivation device, which relates to the technical field of plant hydroponic devices and comprises a cultivation pool, a cultivation area and floating control areas are divided on the cultivation pool, the cultivation area is positioned between the floating control areas, and a plant cultivation device is placed in the cultivation pool. The plant cultivation device comprises a main body frame, a planting part and a floating part, the planting part is placed on the main body frame, a plant is planted in the planting part, a root system extends out of the bottom of the planting part, the floating part is installed on the main body frame, the planting part corresponds to the cultivation area, the floating part corresponds to the floating control area, and the floating part is arranged in the floating control area in a floating mode. The floating height of the floating part is adjusted through the amount of water injected into the floating control area, so that the degree of soaking the plant root system in the culture area is adjusted (the soaking depth of the plant root system is adjusted), oxygen deficit and root rot caused by excessive soaking of the plant root system are avoided, and meanwhile the situation that growth is affected by insufficient soaking of the plant root system is avoided.
