aristolactam/aristolochia

We performed a sequestration study of aristolactams (ALs) from Aristolochia chilensis in Battus polydamas archidamas (Lepidoptera: Papilionidae) by examining the AL content of the plant, fifth instar larvae, osmeterial secretion, pupae, exuviae and feces. Aristolactam-I (AL-I) and aristolactam-II

A new aristolactam, aristolactam 9-O-β-D-glucopyranosyl-(1→2)-β-D-glucoside, and two alkamides, N-cis- and N-trans-p-coumaroyl-3-O-methyldopamine, were isolated from stems of Aristolochia gigantea, together with the known compounds allantoin, E-nerolidol, β-sitosterol, (+)-kobusin, (+)-eudesmin,

Phytochemical investigation of 85% ethanol extracts from the roots of Aristolochia fangchi yielded a new aristolactam derivative named 6-methoxyl aristolactam I N-β-glucoside (1), together with four known compounds, aristolactam IVa (2), aristolactam I-β-D-glucoside (3), aristolactam I (4), and

Astragalin was isolated for the first time along with (-)hinokinin, aristolactam I and aristolochic acids (I & II) from the extracts of Aristolochia indica L. using a new, efficient preparative HPLC method. A reversed-phase HPLC method of analysis was developed to analyse the isolated compounds. The

Fourteen aristolochic acid derivatives: ariskanins A-E, 3-hydroxy-4-methoxy-10-nitrophenanthrene-1-carboxylic acid methyl ester, aristolochic acid-II methyl ester, aristolochic acid-IV methyl ester, aristolochic acid-C, -I, -II, -III, -IV, -IVa; nine aristolactam alkaloids: aristolactam,

There is accumulating evidence that Balkan endemic nephropathy (BEN) is an environmental disease caused by aristolochic acids (AAs) released from the decomposition of Aristolochia clematitis L., an AA-containing weed that grows abundantly in the Balkan Peninsula. AA exposure has also been associated

OBJECTIVE To study the chemical constituents of the fruit of Aristolochia debilis. METHODS The compounds were isolated by chromatographic techniqcue and crystal methods, the structures were elucidated by spectrum analysis. RESULTS 8 compounds were isolated from the dry fruit of Aristolochia debilis

From the fruits of Aristolochia contorta Bge, beside the known aristolochic acids IVa and VII, aristolactam-N-beta-D-glucopyanoside, aristoloctam Ia N-beta-D-glucopyanoside, pinitol and daucosterol, a new biflavonoid was isolated. Its structure was determined as

Six new compounds, aristoloxazine A (1), aristoloxazine B (2), 7-methoxytaliscanine (3), humul-7-en-1,4,11-triol (4), 8-hydroxy-β-logipinene (5), and 1β-hydroxy-4(14)-eudesmene (6), corresponding to two sulfur-containing aristoloxazines (1 and 2), an aristolactam (3), and three sesquiterpenes (4-6)

A new acylated glycoside isolated from the roots of Aristolochia contorta (Aristolochiaceae), has been characterized as aristolactam N-(6'-trans-p-coumaroyl)-beta-D-glucopyranoside [2]. Aristolactam-N-beta-D-glucopyanoside [1] was also isolated from the same source. Compound 2 showed relatively

Two new aristolactams, aristolactam E (1) and aristolactam-AIIIa-6-O-beta-D-glucoside (2), three novel benzoyl benzyltetrahydroisoquinoline ether N-oxide alkaloids, aristoquinoline A (3), aristoquinoline B (4), and aristoquinoline C (5), and a new biphenyl ether, aristogin F (6), together with 62

OBJECTIVE To study the chemical constituents of the fruit of Aristolochia contorta. METHODS The compounds were isolated by chromatographic techniques and crystalization, the structures were elucidated by spectrum analysis. RESULTS Fifteen compounds were isolated from the dry fruit of A. contorta,

An international symposium, held in Zagreb, Croatia, in October 2006, brought together basic scientists and clinical investigators engaged in research on endemic (Balkan) nephropathy, a chronic renal tubulointerstitial disease of previously unknown cause that often is accompanied by upper urinary

Aristolochiae Fructus, a Chinese herbal medicine derived from the fruit of Aristolochia contorta Bge., contains nephrotoxic aristolochic acid analogues (AAAs). According to ancient medical texts, various medicinal parts of the fruit of A. contorta were ever used. In order to reveal which part could
