Cheonggukjang is one of the traditional fermented soy-based foods in Korean diets. Studies in cell cultures, humans have revealed anti-hypertension, anti-stress, anticancer, antioxidant, immune enhancing effects. Angelica gigas, Rehmanniae radix, and Red ginseng are popular medicinal plants and widely used for oriental medicine. In this study a strategy had been developed to mobilize beneficial phenolics from Angelica gigas, Rehmanniae radix, and Red ginseng combined with fermented soy by Cheonggukjang fermentation for antioxidant and Type II diabetes management. The quality and functional characteristics of Chenggukjang fermented with Angelica gigas, Rehmanniae radix and Red ginseng. Cheonggukjang (CKJ), Angelica gigas Cheonggukjang (CKJ-DD), Rehmanniae radix Cheonggukjang (CKJ-RG), Angelica gigas and Rehmanniae radix Cheonggukjang (CKJ-DD+RG) and Red ginseng Cheonggukjang (CKJ-RED) were evaluated. The mobilized phenolic profile was evaluated for antioxidant activity and the potential to inhibit ${\alpha}$-amylase linked to hyperglycaemia. This research has important implications for the development of functional soy-based-fermented foods enriched with Angelica gigas, Rehmanniae radix and Red ginseng phenolics for oxidative stress - induced diabetic complications. Furthermore, Hunter's color values of 5 types cheonggukjang, lightness (L-values), redness (a-values) and yellowness (b-values) were evaluated. Free amino acid content of CKJ-RED (0.993 mg/gd. w.) showed higher than that of CKJ (0.205 mg/g-d.w.).

Angelica gigas Nakai is one of the most widely used herbal medicines and is known to have many pharmaceutical effects including an anti-oxidant, anti-cancer etc. This study was carried out to investigate an effect of fertilization on leaf yield, production of dry-matter and accumulation of pyranocurmarine compounds such as decursin (DE) and decursinol angelate (DA) in Angelica gigas Nakai. Effect of fertilization was determined from response surface regression equation composing of 2 by 3 factorial arrangement of urea, sodium dihydrogen phosphate and potassium chloride. Yield of leaf in Angelica gigas Nakai significantly increased until 100 days after transplanting. Production of leaf also tended to increase with increasing nitrogen fertilization. Model of regression equation showed that leaf production depended upon nitrogen ($Pr>{\mid}t{\mid}$ : 0.087, 0.256 and 0.079). Also, statistical results between nitrogen application level and production of dry-matter showed significant relationship (p<0.05) and contents of dry-matter was highest in 10 kg 10a-1 treatment on 24 Sep. Active compound isolated and purified from leaf and root of Angelica gigas Nakai was identified as DE and DA by gas chromatograph-mass spectrophotometry (GC-MS). Concentration of DA as prevalent compound in leaf was highest on 20 Aug. but decreased on 24 Sep. Amount of DE and DA accumulated in Angelica gigas Nakai significantly increased with growth stages and nitrogen level. The result of our investigation imply that nitrogen fertilization is important factor for production of leaf and accumulation of pyranocurmarine in Angelica gigas Nakai as a medicinal/food materials.

'Angelica' is one of the most traditionally consumed medicinal herbs around Northeast Asia including Korea for treatments of various diseases or health care purposes like hematopoiesis, blood circulation for women, sedative, analgesic, and a tonic medicine etc. Angelica gigas Nakai, a Korean native species of Angelica, is clearly different from the others in containing a high concentration of active ingredients like pyranocoumarines including decursin, decursinol, and decursinol angelate. These compounds have various kinds of positive effects such as anti-tumor activity including the precaution of neutropenia occurred during anticancer drug administration, improvements of metabolic disorders, menstrual irregularity, impairment of renal function, respiration improvement, cognition-enhancement, anti-inflammatory effect, anti-oxidative effect, enhancing fertility and so forth. Thus it implies incredible potentialities in future development for foods and drugs. However, certain purity-related qualities and/or overdose in food products can cause side effects like toxicities; therefore, their safety profiles should also be considered. This review focuses on the positive and negative effects of three pyranocoumarines in Angelica gigas Nakai and some possibilities and considerations for future food and drug products development.
