Embodiment

[0015] 1. Extraction method

[0016] Weigh 20g of Chinese Torreya torreya in a 500ml Erlenmeyer flask with a stopper, add 200ml of 90% ethanol, extract at room temperature for 24h, and then extract with ultrasonic vibration for 1h. Continuously extract 3 times according to the above method, combine the 3 extractions, and then concentrate under reduced pressure below 50°C to form an extract. Use 90% ethanol to disperse the extract and settle to 80ml, and prepare the active test solution to be tested with a concentration equivalent to 0.25g dry sample / ml solvent.

[0017] 2. Bioassay method

[0018] Spread two layers of filter paper of appropriate size in a 9cm petri dish first, then add 2ml Chinese Torreya extract, after the solvent evaporates to dryness, add 3ml deionized water, and spot freshly germinated wild oats, barnyardgrass, retroflexus and 20 seeds of Artemisia persicae, each treatment was repeated 3 times, and 90% ethanol was used as a control. All treatments were ...

Abstract

An application of Chinese cephalotaxus in preparing herbicide includes extracting the herbiciding component in organic solvent, separating and preparing herbicide. Its advantage is high herbiciding activity to weeds including wild oats, barnyard grass, etc.

Description

1. Technical field: [0001] The invention relates to the application of a plant with herbicidal activity, which can be applied to agricultural herbicides. 2. Background technology: [0002] Chinese torreya, also known as torreya, is a plant of the genus Tricuspidaceae, which is a unique tree species in my country. Chinese Torreya is an important raw material of harringtonine anticancer drugs, widely distributed in my country, produced in Jiangsu, Anhui, Fujian, Jiangxi, Henan, Hunan, Hubei, Shaanxi, Gansu, Sichuan, Yunnan, Guizhou, Guangxi And 14 provinces including Guangdong. [0003] The literature shows that the research on Torreya chinensis mainly focuses on the anti-cancer aspect, and there are also sporadic reports on the anti-plant virus activity of the alkaloid synthetic analogues of this plant. However, there are very few reports on the antibacterial and herbicidal activities of Chinese Torreya sinensis. Researchers from the Pollution-Free Pesticide Research Servic...
