Description

Technical Field

[0001] The invention belongs to the field of biomedicine, and particularly relates to a corn feces silk composition with the efficacy of lowering three highs, a preparation method thereof, and an application thereof. Background Art

[0002] Corn silk, the style and stigma of the grass plant Zea mays, is often harvested during the corn harvest. It is mild in nature, sweet in taste, and enters the kidney, liver, and gallbladder meridians. Its main active ingredients, including flavonoids, polysaccharides, and total saponins, have been shown to have diuretic and detumescent properties, soothe the liver and promote bile secretion, dilate peripheral blood vessels, lower blood pressure, lower blood lipids, and lower blood sugar, promote bile secretion, and accelerate bile contraction. Studies have shown that corn silk extract can reduce glucolipid toxicity in type 2 diabetes and its damage to the pancreas, heart, liver, and kidneys, delaying the progression of diabetes and its complications. It can also be used to reduce appetite, prolong gastric emptying time, improve intestinal motility, increase bowel movements, and ultimately reduce weight.

[0003] The tassel is the part of the corn plant that contains the male stamens. It's light green with red and shaped like an inverted broom. The inflorescence of a corn tassel consists of an upright main axis with branches. Short-stalked male florets, as small as wheat kernels, are densely distributed along the main axis and branches.

[0121] Test Example 2 Investigation of the Effect of the Composition of the Present Invention on Improving Gastrointestinal Motility

[0122] 48 healthy, clean-grade male mice of the Kunming strain weighing 18-22g were selected. During the test, the test animals were free to eat and drink deionized water and were placed in a room temperature of 20°C to 24°C and a relative humidity of 55% to 68%. The test animals were randomly divided into four groups: a control group (gavage of the corn silk composition of comparative example 1 at a dosage of 0.6g / kg.bw, extracted with boiling water for 30min, and then cooled to room temperature and then gavage), a test group (gavage of the corn silk composition of example 1 at a dosage of 0.6g / kg.bw, extracted with boiling water for 30min, and then cooled to room temperature and then gavage), a blank group (0g / kg.bw) and a model group (0g / kg.bw) were given water instead of the test substance. Each group was given a maintenance feed and gavage once a day, with a daily gavage volume of 0.5ml / kg.bw. After the test animals were continuously administered the test substance for 14 days, each group of mice was fasted but not watered for 16 hours. The control group, experimental group, and model group were gavaged with loperamide hydrochloride (5.0 mg / kg.BW), and the blank group was given the corresponding volume of distilled water. 30 minutes after the test animals were gavaged with loperamide hydrochloride, the test group and control group were gavaged with ink (containing 5% activated carbon and 10% gum arabic) containing the test substance, and the blank group and model group were given the corresponding volume of ink. The gavage volume of the test animals was 5 mL / kg.BW. 30 minutes after gavage, the test mice were immediately killed by cervical dislocation, the abdominal cavity was opened and the mesentery was separated, and the intestinal tube from the pylorus at the upper end to the ileocecal region at the lower end was cut. The intestinal length was measured as the "total small intestine length", and the distance from the pylorus to the ink propagation front was measured as the "ink propagation length". The ink propagation rate was calculated according to the following formula: Ink propagation rate (%) = ink propagation length (cm) / total small intestine length (cm) × 100%. Results are shown in Figure 1 .

A blank group (gavage with 0.5ml / kg.bw of normal saline), a control group (the corn silk composition of comparative example 1, 1.2g / kg.bw, extracted with boiling water for 30min, cooled to room temperature and then gavage), and test groups 1-3 (the high dose 1.2g / kg.bw, medium dose 0.6g / kg.bw, and low dose 0.3g / Kg.bw of the corn silk composition of Example 1, extracted with boiling water for 30min, cooled to room temperature and then gavage). Gavage with 0.5ml / kg.bw every day, once a day, for 10 consecutive days. One hour after the last gavage, the animals were anesthetized with ether, blood was collected from the abdominal aorta, anticoagulated with heparin, and the following indicators were detected.
