안동산 두충의 유효성분 및 물성 비교 분석

Backgrounds : Eucommiae cortex is traditionally being used for therapeutic agent. It is commonly known as Du-choong in Korean. Previous reserch has shown that it exerts a various beneficial effects such as anti-oxidant, anti-inflammatory, anti-hypertention, and the other pharmachological efficacy. Although Du-choong has recently been shown to exert various effects, whether the primary component or texture of Du-choong associated with supplier are similar is currently unknown. Objective : The aim of this study is to compare and evaluate ingredient and charicteristics according to supplier of Du-choong which is produced in Andong. Methods : Pinoresinol-diglucoside, which is the bioactive compound of Eucommiae cortex is detected using HPLC. Physicochemical characteristics of Du-choong collected from the different supplier were analyzed nutritional compositions of Du-choong. And physical properties measured by texture profile analyzer. Results : HPLC analysis showed that Pinoresinol-diglucoside content of Du-choong supplied by Boro was the highest of 103.4 ㎍/㎖, otherwise, its content by Daehoon herbal medicine dealer was the lowest of 10.9 ㎍/㎖. The highest protein and sodium contents among general nutrition compositions are Du-choong supplied by Jung woo Dang. Moreover, Du-choong supplied by Daehoon herbal medicine dealer with the highest hardness needed a high energy both gumminess and chewiness. Conclusions : Taken together, the primary component or texture of Du-choong grown at Andong associated with supplier are many derivations. Accordingly, the additional researchs about Du-choong cultivated in different districts are asked. And then, it is necessary to standardize the manufacturing process for harmonious supply of effective Du-choong.
