preparation example Construction
[0044] The present invention also provides a preparation method of caryophyllic acid, which comprises preparing the compound from a plant of the genus Fusarium (such as Physanthus falciparum). Preferably, caryophyllic acid is prepared from the roots, stems, leaves, and fruits of a plant of the genus Fusarium lentils. Preferably, the method has the steps of:
[0045] (1) extracting with a solvent after drying and pulverizing the lentils, and merging the extract;
[0046] (2) concentrating under reduced pressure the extract in (1) to obtain extractum;
[0047] (3) suspending the extract in (2) in water, extracting with sherwood oil, ethyl acetate and n-butanol successively, and then steaming off the solvent with a rotary evaporator to obtain sherwood oil, ethyl acetate and n-butanol respectively. butanol extract;
[0048] (4) The ethyl acetate extract in (3) was separated by silica gel column chromatography, and 8 components (Fr.1-8 ).
[0049] (5) Purify Fr.2 in (4) by Sep...

[0061] Inhibitory activity of lentil extract on acetic acid writhing response in mice
[0062] Source of material: The lentils of the genus False, the lentils of Lijiang and the lentils of southern Yunnan; they were collected in Kunming, Lijiang and Mengzi, respectively, and identified as Dolicostrilobus L., D.appendiculatus by Associate Professor Yang Qingsong, College of Ethnic Medicine, Yunnan University for Nationalities Hand.-Mazz, and D.junghuhnianus Benth. The specimens are preserved in the Herbarium of the School of Medicine for Nationalities, Yunnan University for Nationalities.
[0063] Preparation of the lentil lentil extract: crush the root of the lentil lentil to obtain the root fragments of the lentil lentil; then extract the lentil lentil fragments with 95% ethanol / water reflux for 3 times, each time for 2 hours to obtain the extract ; Filtrate the lentil extract and concentrate it under reduced pressure with a rotary evaporator to obtain an extract for later u...

[0071] Further experiments with sickle lentils
[0072] Example 1 was repeated using 95% methanol / water, 70% ethanol / water and 70% acetone / water as extraction solvents respectively. The experimental results show that 95% methanol extract, 70% ethanol extract and 70% acetone obtained by using 95% methanol / water, 70% ethanol / water and 70% acetone / water as extraction solvents respectively The extract of / water also has significant inhibitory activity to the mouse acetic acid writhing reaction, so using different concentrations of ethanol / water, methanol / water or acetone / water as the extraction solvent can also obtain the mouse acetic acid writhing in the sickle lentil Components that inhibit body reactions. The results are shown in Table 2.
