Problems solved by technology

However, most of the studies so far are limited to the flavonoids in flowers and flower buds, and there is little research on other parts, such as roots, stems, leaves and seed coats. It is believed that the stems and leaves after removing flowers and flower buds are relatively old and have no edible value. waste or fuel

Abstract

The invention provides an abelmoschus manilhot stem and leaf high-efficiency comprehensive utilization method. The method comprises extracting flavone from abelmoschus manilhot stem and leaf, preparing different dosage forms of health foods from the extract, and preparing animal feed or a feed additive from the extraction residues. The method can efficiently extract flavonoids in the abelmoschus manilhot stem and leaf and realize recycle of the extraction residues thereby fully improving a utilization rate of the abelmoschus manilhot stem and leaf.

Description

technical field [0001] The invention relates to the field of agricultural product processing, in particular to a high-efficiency comprehensive utilization method of hollyhock stems and leaves. Background technique [0002] Abelmoschus manihot (L.) medic, also known as wild hibiscus, yellow sunflower, okra, cotton sunflower, etc., belongs to Malvaceae malvaceae, and okra belongs to Abelmoschus medicus. Annual or perennial herb. The original ecology grows in the valley grass, field edge or ditch side shrubs in the Taihang Mountains of Hebei. It has strong adaptability and is not strict with the soil, but it is suitable for well-drained and loose sandy loam. [0003] The pharmacological effects of hollyhock have been clearly recorded in medical records of all dynasties, and the history of folk consumption has been more than a thousand years. Modern pharmacological research shows that the pharmacological efficacy of marshmallow comes from bioflavonoids. The content of bioflavo...
