| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

OBJECTIVE: To study the chemical constituents of the fruit of Aristolochia contorta. METHOD: The compounds were isolated by chromatographic techniques and crystalization, the structures were elucidated by spectrum analysis. RESULT: Fifteen compounds were isolated from the dry fruit of A. contorta, which were six aristolochic acids: aristolochic acid I, aristolochic acid III a, aristolochic acid IVa, aristolochic acid II, aristolochic acid III and aristolochic acid VIIa. Three aristolactams: aristololactam I, Aristololactam II and Aristololactam IIIa. Three phenolic acids syringic acid, vanillic acid and p-coumaric acid. Three other type compounds: pentacosane acid, beta-sitosterol and daucossterol. CONCLUSION: Aristolochic acid III, aristolochic acid VIIa, Aristololactam IIIa, and penfacosane acid were isolated from A. contorta for the first time, and compounds 4-13 were isolated from the furit of A. contorta for the first time.
Studies on morphology and aristolochic acid analogue constituents of Asarum campaniflorum and a comparison with two official species of Asari radix et rhizoma.[Pubmed:20640524]
J Nat Med. 2010 Oct;64(4):442-51.
Dried whole herbs or roots and rhizomes of Asarum campaniflorum have been sold under the trade name Xixin and used as folk remedies in its producing areas for a long time. In order to avoid the misuse of A. campaniflorum as official species of Xixin (Asari radix et rhizoma), a comparative study based on the morphological and phytochemical analysis of the aerial and underground parts was carried out. The usual morphological methods and a microscopic imaging system were used. The results show that A. campaniflorum could be easily distinguished from two official species (Asarum sieboldii and A. heterotropoides var. mandshuricum) by the diameter of thicker roots (1.3-2.7 mm), distinct large parenchymatous cells in phloem of roots, and the size of oil cells in upper leaf epidermises [(40)80-140(174) microm in diameter, where numbers in parentheses are for rare cases], etc. Nine aristolochic acid analogues (AAAs) were identified and estimated by high-performance liquid chromatography-diode array detection (HPLC-DAD). The aerial and underground parts of A. campaniflorum contained 3-4 AAAs, i.e., aristololactam-II-N-beta-D-glucoside (AL-II-Glc), aristololactam I (AL-I), Aristololactam II (AL-II), and aristolochic acid I (AA-I), while only AL-I was detected in underground parts of A. sieboldii and no AAAs were detected in underground parts of A. heterotropoides var. mandshuricum. The respective contents (in mg/g) in aerial and underground parts of A. campaniflorum, were as follows: AL-I, 0.06-0.12, 0.05-0.10; AL-II, 0.03-0.04, 0.01-0.03; AA-I, 0.01-0.02, 0.0-0.0. These data suggest A. campaniflorum has a high risk of causing aristolochic acid nephropathy. All these discoveries can contribute to not only the better understanding of this new resource species, but also the safe use of the crude drug Xixin.
