preparation example Construction

[0107] The preparation method of 1.10% picroderm mother liquor, emulsion in water

[0108] (1) 10% mother liquor of phatericin

[0109] Weigh the shade-dried roots or / and bark of bitter vine, pass through a 10-24 mesh sieve after crushing, and use 5-7 times the volume of benzene to ultrasonically extract 1-2 times at 45-55°C, each time extracting 35~ After 55 minutes, the filtrates were combined and then concentrated under reduced pressure to an extract with a density of about 1.1 to 1.3 to obtain 10% pharene mother liquor.

[0110] (2) 2% bitter bark vine water emulsion

[0111] After stirring and mixing 10% phaerectin mother liquor and emulsifier according to a certain proportion, add a certain proportion of antifreeze and make up the balance with water, and after shearing and homogenizing, 2% pharene in water emulsion is obtained.

[0112] The mixing ratio of 2% paterogenin aqueous emulsion is as follows:

[0113] 15-20% mother liquor of 10% paterogenin, 8-12% emulsifier...

Embodiment 1

[0272] Example 1: Preparation and control effect of 10% phalaenin mother liquor and 2% phalaetanin aqueous emulsion

[0273] (1) Preparation of 10% mother liquor of pateratine

[0274] After sieving, the root and bark of the bitter vine that meets the requirements (24 meshes) is mixed with 5 to 7 times the volume of benzene (raw material: benzene = kg: L, that is, 5 to 7 L of benzene is used for 1 kg of bitter vine root and bark). ) Ultrasonic cycle extraction at 50°C for 35~55min (ultrasonic power 500W) 1~2 times (extraction conditions are the same for each time), the filtrates are combined and concentrated under reduced pressure to form an extract of 1.1~1.3, that is, 10% paterogenin mother liquor . See the table below for specific data.

[0275]

[0276] (2) Preparation of 2% Paleophyllin Water Emulsion

[0277] Put the qualified 10% phalaetanin mother liquor in the reaction kettle, add the auxiliary materials (emulsifier and antifreeze) in the following table accordi...

Embodiment 2

[0300] Example 2: Quality detection method of 10% paterogenin mother liquor (Xichuan, Henan Province) IGD carbon nuclear magnetic resonance coupled fingerprint

[0301] (1) Preparation of mother liquor characteristic extract

[0302] Select 10% paterogenin mother liquor (Xichuan, Henan), and prepare the characteristic extract of 10% paterogenin mother liquor according to the following method: Weigh 20 g of 10% paterogenin mother liquor, filter and concentrate under reduced pressure at 60°C, Recover the solvent to an extract form, dissolve the extract with 6 times the volume (120mL) of methanol with a mass ratio of 80%, extract once with 3 times the volume (60mL) of petroleum ether, each extraction for 30min, and filter the methanol layer Concentrate under reduced pressure, recover the solvent to dryness, and obtain the characteristic extract of 10% pharene mother liquor (Xichuan, Henan).

[0303] (2) Feature extraction IGD carbon NMR spectrum test

[0304] Take 80mg of the c...

Abstract

The invention relates to celangulin mother liquor and emulsion in water, a preparation method and a quality inspection method thereof. The celangulin mother liquor comprises, by mass, active ingredients of 1.9-3.5% of angulatin A, 3.0-5.0% of angulatin B, 2.5-4.0% of angulatin G and 2.50-4.10% of angulatin E. The celangulin mother liquor is prepared by an ultrasonic recycling extraction method, and the quality inspection method adopts the IGD carbon-13 nuclear magnetic resonance spectroscopy coupling fingerprint technology. The celangulin mother liquor content is increased greatly, and accuracy, stability, repeatability and feasibility of the quality inspection method are high.

Description

technical field [0001] The invention belongs to the technical field of botanical pesticides, and in particular relates to a picroderm mother liquor and its water emulsion, as well as their preparation method and quality detection method. Background technique [0002] Botanical pesticides are a branch of biological pesticides, which use certain types of stable ingredients contained in plants as active ingredients to kill insects and bacteria. Since these active ingredients are derived from the plant itself, they are easy to decompose naturally; and have structural diversity, it is difficult for harmful organisms to develop resistance. Therefore, botanical pesticides will be one of the main directions for the development of green pesticides in various countries in the world in the future. Domestic botanical pesticides include pyrethrum, azadirachtin, matrine, nicotinic insecticides, and pectinoids [①Wei Yanmin. Q&A on biological pesticides and their application techniques. Ch...
