2. Chemical constituents in cane of Pueraria lobata
Chinese Traditional and Herbal Drugs 2011;42(4):649-651
Objective: To study the chemical constituents from the cane of Pueraria lobata. Methods: The compounds were isolated by column chromatography over silica gel and purified by Sephadex LH-20 column chromatography and preparative TLC. The structures were elucidated by means of physicochemical properties and spectroscopic analyses. Results: Eleven compounds were separated and identified as: dehydrovomifoliol (1), blumenol A (2), 3β-hydroxy-5α,6α- epoxy-7-megastigmen-9-one (3), liquiritigenin (4), garbanzol (5), ferulaldehyde (6), 2,4-dihydroxybenzaldehyde (7), 4-hydroxy-2-methoxybenzaldehyde (8), (-)-tuberosin (9), coumestrol (10), and β-sitosterol (11). Conclusion: Compounds 1-3 are sesquiterpenoids, which are firstly isolated from the plants of Pueraria DC., and compounds 4-8 are obtained from the plants of Pueraria DC. for the first time.

One hundred and fifty-seven cases of Graves' disease were divided into three groups according to their clinical features and thyroid functions: Group A, untreated; group B, treated but uncontrolled or relapsed; group C, treated and remitted. The positive rates of TSH receptor antibody (TRAb), anti-tnyroglobulin antibody (TgAb), anti-microsomal antibody (TmAb), anti-DNA antibody and anti-nuclear antibody (ANA) were 91.2, 79.4, 79.4, 70.6 and 23.5% respectively in group A. The positive rate of TRAb and TBII were significantly different between group C and group A or B (both P
