Abstract: The present disclosure relates to a composition for antiobesity, which contains a Gynostemma pentaphyllum tea or a Gynostemma pentaphyllum tea extract as an active ingredient. The composition of the present disclosure, which contains a Gynostemma pentaphyllum tea or a Gynostemma pentaphyllum tea extract as an active ingredient, is effective for preventing, alleviating or treating diabetes, obesity, muscle loss, etc. since it exhibits the efficacy of increasing AMPK activity, promoting beta oxidation, promoting glucose uptake, etc. In addition, since the composition of the present disclosure is derived from a natural product, it can be safely used as a drug, food, etc. without side effects.

Abstract: The present invention relates to: an Agrimonia eupatoria extract preparation method for promoting the recovery rate and bioavailability of an active ingredient; and a composition for improving liver functions or treating liver diseases, containing the extract. More specifically, the present invention provides an Agrimonia eupatoria extract preparation method capable of extracting Agrimonia eupatoria by using a solvent in which cyclodextrin is dissolved, thereby increasing the recovery rate and bioavailability of an active ingredient, and provides a health functional food for improving liver functions or an agent for treating liver diseases, the food and the agent containing an Agrimonia eupatoria extract and having enhanced efficacy.

Abstract: The present invention relates to a method for producing an enzymatically treated catechin product with increased contents of gallic acid, epicatechin (EC), and epigallocatechin (EGC), an enzymatically treated catechin product produced by way of the method, and use thereof.

Abstract: The present invention relates to a device and method for reconstructing low-frequency conductivity images using MRI without current injection. In the device according to the present invention, low-frequency conductivity is deduced using high-frequency conductivity obtained using MR-EPT, the calculated directional tensor of ions from the water diffusion tensor in a subject, and the volume fractions and diffusion coefficients of the intracellular/extracellular spaces, and low-frequency conductivity images are reconstructed based on the deduced low-frequency conductivity. According to the present invention, low-frequency conductivity images in a subject to be measured such as the human body and an object may be reconstructed using an MRI device without applying current to the subject.
