人类暴露研究/迄今为止报告的最大爆发发生在阿富汗西北部赫拉特省的古兰区,靠近苏联边境。...据估计,疫情影响了大约35,000人,分布在98个村庄。对受影响村庄的7,200名居民进行检查,发现22.6%有疾病证据,其中15%情况严重。因此,估计大约有8,000人患有这种疾病,包括5,000人严重受影响。所有年龄组的人都受到影响,但46%的受试者年龄在14岁以下。然而,在2岁以下的儿童中没有发现疾病的迹象。关于从14个肝脏活检和8个尸检中获得的病理材料的详细报告已经完成.../尽管/没有指出症状发作和活检/尸检之间的时间间隔。病理发现具有特征性,从具有特征性静脉闭塞的急性疾病到非门脉性肝硬化,这在上述22例中有5例观察到。疫情被归因于小麦的大规模污染,小麦是主要粮食作物,在连续两年干旱之后,与Heliotropium popovii H. Riedl subsp. gillianum H. Riedl的种子混合,这种植物在小麦作物中大量生长。这些种子含有吡咯烷生物碱,两个实验室报告的浓度分别为7.2和13.2-14.9 g/kg,主要被识别为heliotrine的N-氧化物(74%)...,还有一两种其他与lasiocarpine性质相似的化合物。来自几个村庄的小麦样本平均每千克含有40颗种子,即重量的0.03%。据估计,成年人每天至少消耗700克面粉,含有大约2毫克生物碱(基于种子分析的平均值)。/吡咯烷生物碱/
/HUMAN EXPOSURE STUDIES/ The largest outbreak reported to date occurred in the Gulran district of Herat Province in northwest Afghanistan, close to the border of the USSR. ...The outbreak, was estimated to have affected a population of approximately 35,000 in 98 villages. Examination of 7,200 inhabitants of the affected villages showed evidence of disease in 22.6%, which was more serious in 15%. Thus, it was estimated that approximately 8,000 subjects suffered from the disease including 5,000 who were seriously affected. All age groups were affected, but 46% of subjects were below 14 years of age. However, no sign of disease was found in children below 2 years of age. A detailed report concerning the pathological material obtained from 14 liver biopsies and 8 autopsies was made... /although/ the time interval between the onset of symptoms and the biopsy/autopsy was not indicated. Pathological findings were characteristic, ranging from acute disease with characteristic veno-occlusion to non-portal cirrhosis, which was observed in 5 of the above 22 cases. The outbreak was ascribed to massive contamination of wheat, the staple food crop, following 2 years of drought, with the seeds of Heliotropium popovii H. Riedl subsp. gillianum H. Riedl, which had been growing profusely among the wheat crop. The seeds contained pyrrolizidine alkaloids at concentrations reported by 2 laboratories to be 7.2 and 13.2-14.9 g/kg, identified mainly as the N-oxide of heliotrine (74%)..., and one or two other compounds similar in character to lasiocarpine. Samples of wheat from several villages contained an average of 40 seeds/kg, i.e., 0.03% by weight. It was estimated that an adult consumed at least 700 g flour/day, containing approximately 2 mg alkaloid (based on a mean of the seed analyses). /Pyrrolizidine alkaloids/

Identification of Adducts Formed by Reaction of Purine Bases with a Mutagenic Anthraquinone, Lucidin: Mechanism of Mutagenicity by Anthraquinones Occurring in Rubiaceae Plants.
A mutagenic anthraquinone, lucidin (1), occurring in Rubiaceae plants, reacted with nucleic bases under physiological conditions to form adducts. The order of the reactivity is as follows: adenine > guanine >> pyrimidine bases approximately 0. By spectroscopic analyses, the isolated purine base adducts were identified as condensed reactants at the benzylic position of 1 with a nitrogen atom of a purine

Abstract From Galiummollugocell suspension cultures, 1,4-dihydroxy-3-prenyl-2-naphtholic acid methyl ester diglucoside was isolated along with anthraquinones and mollugin. Production of the diglucoside was much increased by administering 2-succinylbenzoate to the cultures. The incorporation of 2-succinylbenzoate into lucidin-3-primeveroside, mollugin and the diglucoside in the mode so far proposed
In a series of searches fot DNA topoisomerase II inhibitors from naturally occurring compounds, a wood extract of Neonauclea calycina MERR. (Rubiaceae) showed a moderate effect in vitro. Purification of the extract resulted in the isolation of seven known anthraquinones. The structures were characterized as damnacanthal, rubiadin 1-methyl ether, nordamnacanthal, morindone, damnacanthol, lucidin 3-O-primeveroside and morindone 6-O-primeveroside by spectral analysis, respectively. Damnacanthal and morindone showed an intensive inhibitory effect against topoisomerase II (IC50 : 20μg/ml and 21μg/ml).

with 37% hydrochloricacid: methanol: water (2:1:1, v/v/v), but this solvent system hydrolyses dye glycosides and may also induce chemical reactions. One of the primary components in Dyers' madder (Rubia tinctorum L.) is lucidin primeveroside, but it is rarely seen in artefacts, nor is the corresponding aglycon lucidin. It has been demonstrated that the hydrochloricacid method causes hydrolysis of anthraquinone
存在于不同茜草物种中的着色剂的复杂混合物可以提供有关使用哪种植物物种或技术对历史纺织人工制品的纤维进行染色的重要信息,因此,从纺织人工制品中提取和分析着色剂时,应尽可能多地获取这些信息。保留。历史悠久的纺织品通常使用37%的盐酸:甲醇:水(2:1:1,v / v / v)萃取,但是这种溶剂系统会水解染料糖苷,还可能引起化学反应。Dyers'madder(Rubia tinctorum)的主要成分之一L.)是lucidin primveroside,但在人工制品中很少见到,相应的糖苷配基糖苷也没有。已经证明,盐酸方法使蒽醌糖苷水解成它们的糖苷配基。在此证明,在这种酸性条件下,lucidin不稳定,并迅速降解为黄嘌呤嘌呤。HPLC,LC-MS和1 H NMR证实了这一点,这也提供了降解机理为逆醛醇缩过程的证据。
