PHAMACEUTICAL AND HEALTH FOOD COMPOSITION FOR PREVENTING OR TREATING HYPERTENSION COMPRISING DEHYDROABIETIC ACID OR COMMUNIC ACID AS EFFECTIVE COMPONENT

摘要

According to the present invention, fractions derived from pine leaves with an inhibitory activity on an angiotensin converting enzyme are selected, and dehydroabietic acid and communic acid are identified by identifying structures among the selected materials with optimum activity. Provided are a health promotion food composition comprising dehydroabietic acid or communic acid as active ingredients for preventing or curing hypertension, a pharmaceutical composition for preventing or curing hypertension, an angiotensin converting enzyme inhibitor, and a pharmaceutical composition for preventing or curing vascular diseases. According to the present invention, dehydroabietic acid or communic acid derived from pine leaves has angiotensin converting enzyme inhibitory activity, and can be provided as a useful composition for consumer`s health. Since a method for extracting and segmenting is provided specifically in the present invention, the materials with excellent activity which is abundantly contained in pine leaves can be used as an economical raw material with a high function.
