According to the present invention, provided is a method for manufacturing a plant extract by using concentrated mineral water with high hardness. The method in the present invention can reduce extraction time, and an extract manufactured by the method can be stored at room temperature. Furthermore, according to the present invention, the specific flavor of each low molecular substance included in a raw ingredient is extracted via a non-heating process. Accordingly, the flavor of the raw ingredient can be maximally preserved and extracted. In addition, according to the present invention, the extract is rich in ionized mineral content and can be quickly absorbed into the human body. Moreover, the in vivo absorption rate of a functional ingredient (phytochemical) of a plant extract can be enhanced. A manufacturing method of a plant extract comprises the following steps: (a) mixing a crushed plant and concentrated mineral water with a hardness of 25,000-400,000 mg/L to obtain a homogenized solution (b) keeping the homogenized solution at 3-30°C to extract an ingredient included in the crushed plant and (c) separating a liquid ingredient from an extract obtained in the step (b), and diluting the liquid ingredient with water in a dilution ratio of 1:10-1000 to obtain a plant extract.COPYRIGHT KIPO 2016본 발명은 고경도의 미네랄 농축수를 이용하여 식물 추출액을 제조하는 방법을 제공한다. 본 발명의 방법은 추출시간을 단축시킬 수 있고, 제조된 추출물은 상온 보관이 가능한 저장상의 이점이 있다. 또한, 본 발명은 원재료에 함유되는 각각의 독특한 저분자 물질의 향기를 비 가열에 의하여 추출하므로, 원재료의 향기를 최대한 보존하면서 추출할 수 있다. 또한, 본 발명에 의한 추출물은 이온화 미네랄 함량이 풍부하고, 체내에 신속히 흡수될 수 있으며, 아울러 식물 추출물의 기능성분(파이토케미칼)의 체내 흡수율도 향상시킬 수 있다.
