  • Angelica gigas Nakai (AGN) is a perennial herb belonging to the family Apiaceae. Its root has been utilized as a traditional medicine in Korea. Also, it contains decursin (D) and decursinol angelate (DA) as major active components. This study was performed to compare the change in content of active components and antioxidant activity between bolting and non-bolting AGN. Bolting AGN (B1) and non-bolting AGN (NB1) were harvested in the end of August. Additional non-bolting AGN (NB2) was harvested in the end of October. The total weight of B1 was 728.7 g, which was 98.5% of NB2 weight. Next, the AGN root (B1, NB1 and NB2) was divided into main root and lateral root. And the AGN aerial part (B1, NB1) was divided into flower, leaf and stem. The two active components, D and DA, and antioxidant activity were analyzed. The D content of B1 was 0.35-1.33% according to the plant parts and the DA content was 0.29-1.07%. In addition, B1 flower and leaf showed higher antioxidant activity than NB2 roots. The results show that B1 contained 15-56% of total major components compared with NB2 main roots, suggesting that B1 could be used as a potential material.

  • Centella asiatica (L.) Urban is a medicinal plant containing madecassic acid, triterpenoids and asiaticoside, and has a wound healing effect. However, since it grows only in some regions of Korea, it is necessary to breed stable varieties. In this study, it were analyzed for the growth characteristics, asiaticoside, anxiodant components and 2,2-diphenyl-1picryl hydrazyl (DPPH) radical scavening activity of C. asiatica collected from domestic natural habitat (Hapcheon, Gyeongnam). In the growth characteristics of each resource, CA9 and CA10 were superior in characteristics of aerial part and in dry weight. In asiaticoside content analysis, CA5 and CA3 were high with 53.96 mg/g and 52.40 mg/g, respectively. CA12 showed the possibility of development because the resource showed high in total flavonoid (7.3 mg/g), total polyphenol (10.64 mg/g) and DPPH activity (11.96 mg AAE/g) among other resources. However, it is necessary to select a resource suitable for each characteristic of C. asiatica and to study charateristics through additional resources collection since the excellent growth characteristics of the collected resources do not necessarily coincide with the content and antioxidant activities.
