| Summary: | 碩士 === 弘光科技大學 === 生物產業研究所 === 99 === Angelica acutiloba belongs to the Apiaceae family and Angelica L.genus, which is a perennial herbaceous plant. People use usually it’s rhizome as a traditional medicine for the producing blood, modulating menstruation, hemostasis and treating constipation. But few studies have
been published on the different parts of Angelica acutiloba. In our study, we analyze the general compositions, essential oil, functional constituents and
antioxidative activity in the different parts of Angelica acutiloba.
The results are as follows the yields of essential oil from , rhizome, steam and leaf are 0.4!, 0.48!and 0.18!, respectively. The numbers of identified compounds are 103, 69 and 87 in essential oil from rhizomes, stems and leaves, respectively, and the major compounds are 3-n-butylphthalide, -terpinene, p-cymene and cis-ocimene. The contents of dietary fiber of leaves,stems and rhizomes are 56.47!, 50.70! and 37.37!, respectively, and the percentage of soluble fiber in the dietary fiber is 10!, 11! and 17!, respectively. In the assessment of organic acid: the
rhizomes and stems don’t have oxalic acid component, but the contents of oxalic acid are 4.05mg per 100g leaves; the contents of tartaric acid in the rhizomes, stems and leaves are per 100g samples including 166.82mg, 214.94mg and 29.01mg , respectively"the contents of malic aicd are per
100g samples including 3.4mg, 25.04mg and 34.61mg , respectively; the contents of citric acid are per 100g samples including 2.33mg, 6.38mg and 22.09mg , respectively; and the contents of succinic acid are 3.86mg,
3.59mg and 1.74mg per 100g samples, respectively. It is only finding the 5’-UMP component in the analysis of nucleotide components and the contents of rhizomes, stems, leaves are per 61.34mg, 184.49mg and 182.89mg per 100g samples, respectively. There are contain the most amounts of sucrose about 30.08g per 100g rhizomes. The leaves contain12.56g sucrose per 100g samples, and no finding is noted in the stems. The leaves contain the most amounts of quercetin about 1.20mg per 100g samples, and the contents are almost to be equal in the stems and rhizomes
about 0.7mg per 100g samples. The contents of rutin in the leaves, stems and rhizomes are per 100g samples including 11.35mg, 1.72mg and 0.80mg, respectively. The contents of total phenol of water extracts in the leaves, stem and rhizome are per 100g including 403.59, 144.03mg and 116.97mg, respectively, and the total phenol contents of ethanol extract are per 100g samples including 870.50mg, 255.29mg and 146.30mg, respectively. The ferulic acid components exist only in the rhizomes. The contents of ferulic acid from rhizomes are 0.23! and there are similar ferulic acid contents between the water and ethanol extracts to be about 0.1!. The leaves have the best antioxidative capacity, followed by stems, while the rhizomes are lowest in all the types of antioxidative tests about the DPPH scavenging capability, the chelating effect of ferrous ions, the total antioxidative capacity and reducing capacity. Every type of antioxidative capacities of the water extractions are better than ethanol extracts. Having a consistency between the quantities of rutin, quertin and total phenol compound and the antioxidative capacity.
