Description

Antioxidant composition containing fine cucumber extract {Antioxidant composition comprising extract of Sanguisorba tenuifolia}

The present invention relates to an antioxidant composition containing a fine cucumber extract.

Reactive oxygen species (ROS), called reactive oxygen species, occur naturally in the body's metabolic processes and are also caused by oxidative stress in the body, such as excessive exercise and environmental hormones (Cho et al. 2011). Examples of reactive oxygen species include hydroxyl radical (OH), superoxide radical (O ^2- ), and hydrogen peroxide (H ₂ O ₂ ). Overexpressed ROS can cause damage to cell membranes, proteins, and DNA in vivo. Causes various diseases such as diabetes, hypertension, obesity, and aging (Gardner & Fridovich 1991; Drooge W 2002; Willcox et al. 2004). Therefore, in the functional food, cosmetics and pharmaceuticals industry, to remove such ROS, propyl gallate (PG), dibutyl hydroxyanisole (BHA), and dibutyl hydroxytoluene (BHT) are used. Although synthetic antioxidants have been used, many studies have reported that these synthetic antioxidants cause side effects such as causing cancer or showing intracellular toxicity (Ito et al. 1986; Safer & al-Nughamish 1999). For this reason, researches have been conducted to find natural antioxidants that are safer and more effective than synthetic antioxidants, and researches on natural antioxidants using terrestrial organisms that have been proven effective in folk medicine or herbal medicine. A total of 205 plants, 1,157 genera and 4,940 plants native to Korea are highly diverse compared to the UK (2,000 species) and Denmark (1500 species), which are similar to Korea. As it is distributed, the development of functional materials using them is essential (Kim et al. 2012a).

Therefore, many researchers are conducting functional studies using domestic native plants, and Jeong et al. (2004) investigated the antioxidant activity of 118 domestic native plants for the purpose of developing natural antioxidants. Three hundred seconds, peony, etc. reported excellent antioxidant activity, Choi et al. (2010) studied the antioxidative and antimicrobial activity using seven native herbs and four introduction herbs. In addition, Hyun et al. (2007) and Jang et al. (2015) investigated the antioxidant activity using plants native to Jeju Island and searched for cosmetic materials. Kim et al. (2015a) studied the antioxidant activity of the roots of elm tree roots in relation to the physiological activities of plants native to the forests in Korea. As such, various studies on the individual functionalities of plants native to the forest area have been conducted in various ways, but comparative studies on the anti-oxidative activity of various species of native plants in the forest area have been rarely performed. However, it is considered that the study of the native plants in forest area is very important for the conservation and utilization of native plants in Korea.

Sanguisorba tenuifolia Fisch.ex Link is a perennial herb that grows in high mountains. Root stock is thick. Stems are branched, 50-120 cm high. Leaves from roots are odd pinnate leaves, 20-45cm long. Petals are 3-7 pairs, without petioles, narrow, long lanceolate, 4-15cm long, 5-13mm wide. Sawtooth at edge of leaf Flower blooms in August-September. It is white in full bloom with ear spikes. The inflorescence is long or thin, 3-9cm long and 4-7mm wide. Stamens come out of calyx long, anther is white, pistil is wrapped in calyx, fruit is achene. It grows wild throughout Korea and is distributed in Russia, Japan, China, and Eastern Europe. However, not much research has been carried out on fine cucumber grass yet.

Thus, the inventors of the present invention, while studying the various physiological activity of the fine cucumber grass, confirmed that the extract of the fine cucumber grass has an excellent antioxidant effect to complete the present invention.
