The purpose of this study was to examine physical properties of the addition of Plantago powder on bread flour and dough fheology of white pan bread. Four levels(0.3, 0.6, 0.9 and 1.2%) of each Plantago powder with bread flour were tested for their effects in dough mixing using rapid visco analyzer, alveogram, farinogram and sensory test. Addition of Plantago powder(0.3, 0.6 and 0.9% ) showed almost same tendency on the initial pasting temperature but 1.2% increased it. Increment of Plantago powder showed increment of peak viscosity and final viscosity, L(extensibility) and G(swelling index) value in alveogram showed decrement with increasing Plantago powder. In farinogram the use of Plantago powder increased consistency and water absorption but decreased development time and stability. White pan bread using Plantago powder had higher value of Max. G and gardeness in rheometer than without using it. Sensory evaluation of white pan bread with 0.6% Plantago powder had the highest score.

To develop the functional food, methanol extracts of dried plantain (Plantago asiatica L.) was fractionated in hexane, chloroform, ethyl acetate, butanol and aqueous fraction. DPPH radical scavenging effect, reducing power, nitrite scavenging effect and antimicrobial activities of these fractions were investigated. Ethyl acetate fraction among these fractions showed the highest effect of all experiments. Ethyl acetate fraction showed about 60% scavenging effect on the DPPH radicals at 400 $\mu$g/5 mL. Nitrite scavenging effect of ethyl acetate and butanol fraction was more than 70~80% at concentration above of 500 $\mu$g. Among various solvent fractions from methanol extracts of plantain, ethyl acetate fraction showed the highest inhibitory effect on the microorganism such as Staphylococcus aureus, Bacillus cereus and Vibrio parahaemolyticus at 5 mg/disc.

Plantago asiatica L. (P. asiatica) is a perennial plant belonging to the plantaginaceae and is useful in treating a various diseases such as wounds, bronchitis, and chronic constipation. The bioactive effects of P. asiatica extract was evaluated to determine its potential for use as a variety materials in the food, pharmaceutical, and agricultural industries. Polyphenol and flavonoid contents, free radical scavenging, reducing power activity, and reactive oxygen species (ROS) expression were measured to identify the antioxidative activity. Anti-inflammatory effects were evaluated via analysis of nitric oxide (NO) and pro-inflammatory protein expression in LPS-induced RAW 264.7 cell. As a result of measuring the antioxidant activities of the P. asiatica extract, the total polyphenol content was 50.91±0.78 mg gallic acid equivalents/g and the flavonoid content was 100.99±0.44 mg rutin equivalents/g, and both DPPH and ABTS radical scavenging activities and reducing power increased depending on the concentration. Also, intracellular ROS production was inhibited by the P. asiatica extract. No cytotoxicity was observed when P. asiatica extract was treated, and NO and inflammatory protein expression were inhibited, and nuclear factor kappa B (NF-κB) phosphorylation was also inhibited in a concentration-dependent manner. In conclusion, P. asiatica is a functional natural resources of antioxidant and anti-inflammatory agents that can be used in various industries, including food and agriculture.

The purpose of this study is to determine the possibility of using Plantago asiatica as natural health food source. To accomplish this purpose. the contents of proximate and anti oxidative nutrients of P. asiatica were measured. The contents of carbohydrate. crude protein. crude fat and crude ash are 63.71%, 18.75%, 1.67% and 6.48%, respectively And the calories and total dietary fiber of P. asiatica was 466.71 Kcal. Total dietary fiber was 22.68%, respectively. The contents of essential and non-essential amino acids were 4.815.22 mg and 6.591.04 mg, respectively. The K was the largest mineral followed by P, Ca, Mg, and Na, which means P. asiatica is alkali material. The EDA of P. asiatica was 59.32~70.30%, and the activity was dependent on the sample concentration. Total phenolic content of P. asiatica was $79.65{\mu}g/g$, and total flavonoids content was $4.43{\mu}g/g$. The P. asiatica extract showed the highest reducing power (3.5) at a concentration of 25 mg/mL. Based on the above results, we deemed that the P. asiatica might have potential antioxidant activities. The general nutrients and other antioxidant bioactive materials in P. asiatica were also potential materials for good health food.
