The compound of the present invention is extracted and isolated from Ajiugalimota, for example, in the following manner. That is, first, Ajiugalimota is extracted using a polar solvent such as methanol, and the extract is concentrated under reduced pressure to obtain a primary extract. Next, this primary extract is extracted using a solvent such as ethyl acetate, chloroform, or ether by a solvent partition method, and the extract is concentrated under reduced pressure to obtain a secondary extract. Furthermore, the compound of the present invention can be obtained by subjecting the second extract to silica gel column chromatography and eluting with a suitable solvent such as ethyl acetate-benzene (25:75, V/V). The compounds of the present invention thus obtained can be used, for example, for insects belonging to the order Isopoda such as the pill bug, insects belonging to the order Chiliformes such as Lepsis masaracarina, insects belonging to the order Chrysopoda such as the collembolan, and insects belonging to the order Chrysopoda such as the Japanese termite. Insects that belong to the order Isoptera, insects that belong to the order Liceptera such as the hair louse, insects that belong to the order Pyridiae such as the brown hair louse, insects that belong to the order Thysoptera such as the rice thrips, insects that belong to the Order Order Cryptera such as the human flea, insects that belong to the Order Order Pyroptera such as the human flea, etc. Insects belonging to the order Orthoptera, insects belonging to the order Hemiptera such as the bean aphid, insects belonging to the order Lepidoptera such as the green caterpillar, insects belonging to the order Noctuida such as the diptych moth, insects belonging to the order Coleoptera such as the rice beetle, and hymenoptera such as the sawfly. Excellent insecticide against insects belonging to the order of the order, insects belonging to the order of Diptera such as the yellow-bellied gumfly, insects belonging to the fruit fly class such as the rice black fly, insects belonging to the spider mite class such as the citrus spider mite, and nematodes such as the black nematode. Demonstrate activity. The compounds of the present invention can be used in emulsions, wettable powders, aqueous solutions, suspensions, concentrated suspensions, granules, fine granules, granules, powders, wettable powders, liniments, foam spray preparations, and aerosol preparations. , microcapsule preparations, preparations for impregnating natural or synthetic substances, preparations for fumigation,
It is formulated according to conventional methods into various drugs such as smoking preparations and concentrated small-dose spraying preparations. The compound of the present invention is prepared to contain about 0.1 to 95% by weight, preferably about 0.5 to 90% by weight when producing the various drugs mentioned above, and the drug can be used as it is or in a carrier or with a carrier depending on the purpose. It is used after being diluted with water. When used diluted with a carrier or water, the degree of dilution is not particularly limited and can be appropriately selected within a wide range depending on the purpose of use, but it is important to note that the degree of dilution is not particularly limited and can be appropriately selected within a wide range depending on the purpose of use. It is preferable to dilute it so that it is contained in a proportion of . For example, when using a chemical containing the compound of the present invention for agricultural and horticultural purposes, it is usually sufficient to spray the active ingredient in an amount of about 0.1 to 10 kg per hectare, but of course this will vary depending on the plant and the degree of its disease. It can be increased or decreased as appropriate. Examples are given below. Example 1.1 kg of dried Ajiyu Garimota was crushed and extracted with methanol. This extract is concentrated under reduced pressure to obtain a gummy primary extract, to which 1.5 ml of 50% methanol is added and extracted with hexane until the hexane layer becomes colorless. The obtained lower layer is extracted several times with chloroform, ether, etc. The obtained organic layer was concentrated under reduced pressure to obtain 30 g of a secondary extract. 30g of the secondary extract was added to silica gel (Merck,
Kiesel Gel 60, 70~230 mesh) 350g column and ethyl acetate-benzene (25:75V/V)
The 4.5 g eluted in 800 ml was applied to a 150 g column of activity-neutral alumina and eluted with ethyl acetate-benzene (1:9 V/V) to give colorless needle crystals with a melting point of 167.
300 mg of Clerosin was obtained showing a temperature of ~168°C. Using the above neutral alumina column, 2 g of the fraction eluted next to Clerosine with ethyl acetate-benzene (1:9 V/V) was subjected to high performance liquid chromatography [Column: 7.8 mm x 300 mm, μ-Porasil, solvent;
Ethyl acetate-benzene (25:75V/V), flow rate;

I got 71 mg. Then, by collecting the portion eluted at a retention time of 6.2 minutes using the same high-performance liquid chromatography, 60 mg of the compound of formula (3) was obtained as colorless plate crystals.
Obtained. The physical properties of the compound of formula (2) and the compound of formula (3) thus obtained are as follows.
