JPS59204124A - Preparation of concentrated extract from leaf of sasa albo-marginata - Google Patents

Abstract

PURPOSE:To obtain a concentrated extract of Sasa albo-marginata industrially advantageously without using a specific solvent, by putting dried leaves of Sasa albo-marginata in a pan, immersing them in water, boiling and concentrating them, adding a specific medium to the solution to raise its boiling point, concentrating it further. CONSTITUTION:Raw leaves of Sasa albo-marginata are dried, cut, put in a pan, immersed in water, water-soluble substances are leached, concentrated, and made into a high concentration in a pasty or colloidal state in a condition as it is. A medium (e.g., 0.1wt% sodium bicarbonate solution, air, mixed solution of oxygen and air) is added to the solution in order to raise the boiling point of the leached solution, and the solution is heated at an effective temperature not to reach 200 deg.C caramel modification temperature, in a condensed state until it reaches 120-160 deg.C, for 6-12hr, to give a concentrated extract. By adding the medium to raise the boiling temperature to the concentrated solution of Sasa albo-marginata, the concentrated extract of leaves of Sasa albo-marginata can be mass-produced.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention aims to effectively extract a concentrated extract from the eye level leaves without using any special solvent, and to produce the concentrated extract from the eye level leaves for industrial production in large quantities. In order to improve the method for producing extracts, the raw material is dried and finely sheared fresh leaves at eye level, placed in a pot and submerged in water, exuded water-soluble substances and boiled to form a liquid. A medium to raise the boiling point is charged, and the boiling point is increased within an effective temperature range that does not reach the caramel transformation temperature λθoC, for example, about /2
0 C-'-/lOC and continue heating for about 6 to 12 hours to produce a concentrated extract, or 11. Dry the fresh leaves at the eye level and shear them finely. Take a material as a source material, put it in a pot, soak it in water, exude the water-soluble substances, boil it, concentrate it as appropriate, leave it as it is, and raise the boiling point to the caramelization temperature, The effective temperature range does not reach zooC, for example about l
λo'6~/4071: The process of manufacturing the first concentrated extract by continuously heating it for about 6 to 12 hours in a boiled state until it reaches a degree of Use this as the source material, put it in a pot and submerge it in water to exude the water-soluble substances, boil it, concentrate it as appropriate, and boil it as it is until it reaches about C-/60C. A small amount of the above-mentioned concentrated extract is added to the mixture that has been continuously heated for ~12 hours to make a mixed solution, and the mixed solution is heated within an effective temperature range that does not reach the caramelization temperature of 200 C, for example, about /20 C ~. /1. Boil it down to about OC and heat it continuously for about 1-2 hours, add hot water and boil it, remove the supernatant liquid, boil it again and concentrate it to make the final concentrated liquid. In an embodiment thereof, the paste-like or colloid-like substance is made to have a high concentration and serves as a medium to increase the boiling point of the exudate.
．． /% of baking soda is used, or air or a mixture of oxygen and air is used as a medium to increase the boiling point of the exudate by increasing the paste-like or colloidal concentration to a high concentration. , which is injected into the exudate.

According to this invention, since the viscosity of the extraction solution is high and the solution does not have to be concentrated at high temperature, it is difficult to effectively concentrate the solution and it is difficult to concentrate without using a special solvent. Since the rich extract can be extracted and concentrated from the leaves, the bad side effects caused by solvents are completely removed, and the heating extraction is carried out under high pressure, resulting in a caramelization temperature of 2001: It is now possible to heat the effective extraction temperature of the liquid at the eye level, which does not reach about 100%, to approximately /lOC, so that the extraction process can be completed and concentrated, making the concentrated extract from the eye level liquid even more effective. It can be mass-produced and is extremely useful.

Conventionally, medicinal substances have been extracted from these medicinal herbs by heating.

According to this conventional method, even if a high-pressure cooker is used, the boiling temperature is approximately 110C and cannot be expected to exceed 120C.

Therefore, it is impossible to extract medicinal polysaccharides that are first extracted at an effective temperature range that does not reach the caramelization temperature of 200 i:', for example, about /20 C-#θC.

Focusing on this point, in the invention of prior patent application No. 17-60324' (% Publication No. 17-60324'), in order to extract the concentrated extract from the leaves of Kumazasa without using any special solvent, The raw material is dried and finely sheared fresh leaves, which are placed in a pot and soaked in water to exude water-soluble substances, boiled, and concentrated as appropriate.
Leave it as it is, put a lid on the pot, apply high pressure of about 7 atm, raise the boiling temperature to about /AOC, heat it for about 6 to 1 hours, and then heat the chemical solution. It has been developed to extract

In this prior invention, the extraction process is carried out under particularly high pressure of about 7 atmospheres, so the extraction process inevitably becomes complicated. Therefore, in the invention of this application, instead of the extraction treatment method under high pressure of the prior invention, a medium to increase the boiling temperature of the concentrated leaf liquid at the eye level is charged into the concentrated liquid at the eye level. In many cases, it is possible to boil the concentrated liquid of leaves at eye level to an effective temperature range that does not reach the caramelization temperature of 200 C, for example, about /20 C to /10 C. te, fyi
It is possible to mass-produce a concentrated extract of eye-level leaves with a simple operation.Also, dry and finely sheared fresh eye-level leaves can be used as a raw material, and place this in a pot and submerge it in water to extract water-soluble substances. Exude it, boil it, concentrate it as needed, and use it as it is.
In this state, the exudate is made to have a high concentration in the form of a paste or colloid, and a medium to raise the boiling point of the exudate is charged to raise the willow point.
Effective temperature range that does not reach C
Adding a small amount of the concentrated extract to create a mixed solution, and keeping the mixed solution within an effective temperature range that does not reach the caramelization temperature λθθC, for example, about /,
Boil it until it reaches about 20 C~ito C and heat it continuously for about 6 to 12 hours, add warm water to it, boil it, remove the clear soil liquid, and concentrate it by boiling to obtain the final concentrated liquid. By doing so, the extraction and concentration of the concentrated extract from the leaves at the eye level can be carried out more completely, and the production of the concentrated extract can be carried out effectively, which is extremely useful.
