 The use of assay methods with different test conditions for determination of anthracene derivatives in herbal substances and herbal medicinal products requires adjustment of the established limits for total anthracene derivatives content based on the test method used.The aimof the study was to compare different pharmacopoeial methods of quantitative determination of anthracene derivatives, and established limits for the active substance content, and to analyse the possibility of adjusting the limits based on the test method used.Materials and methods: the total content of anthracene derivatives was measured in the samples of frangula bark (fragmented bark and powder) and senna leaves (fragmented leaves and powder) using the test methods described in the State Pharmacopoeia of the Russian Federation (XI and XIII editions), and the European Pharmacopoeia.Results:the analysis of Russian and foreign pharmacopoeial requirements for determination of anthracene derivatives in laxative herbal medicinal products demonstrated differences in extraction solvents, extraction conditions, and calculation methods used. The experiments showed that the optimal extraction solvent was 70 % alcohol solutions, and that an indirect cobaltic chloride reference standard should be replaced by specific absorbance of glucofrangulin A and sennoside B. It was shown that the limits for total anthracene derivatives content should be chosen based on the extraction conditions used.Conclusions:comparative theoretical research and experimental studies helped to determine optimal assay conditions and respective limits for total anthracene derivatives content to be used in quality control of herbal substances and herbal medicinal products.

The relevance of this study stems from the need for alignment of test methods used for identification and assay of anthracene derivatives in herbal preparations and herbal medicinal products. The aim of the study was to analyse Russian and international quality standards and to identify the most specific and sensitive test methods that could be used for herbal medicines containing anthracene derivatives. The comparative analysis of requirements in the Identification, Determination of major classes of bioactive compounds, and Assay parts of the Russian and foreign pharmacopoeial monographs for herbal preparations and herbal medicinal products containing anthracene derivatives, demonstrated that the main test method used for identification is thin layer chromatography, while assays most often rely on spectrophotometry. The so-called “consistent standardisation” principle is implemented in the Russian quality standards as regards alignment of methods used for anthracene derivative determination in herbal preparations (i.e. active pharmaceutical ingredients, APIs) and herbal medicinal products containing these APIs. The comparative analysis of requirements in the Russian and foreign quality standards for herbal medicines containing anthracene derivatives demonstrated the need for elaboration of two general chapters: Qualitative analysis of anthracene derivatives in herbal medicines and Quantitative analysis of anthracene derivatives in herbal medicines.

Heavy Metals And Arsenic

Herbal medicinal products (HMPs) are widely used in medical practice due to their availability, ease of use, and relatively safe pharmacological profile. However, medicinal plants are capable of accumulating heavy metals and arsenic which can have toxic effect on the human body when found in HMPs. The aim of the study was to summarise and analyse requirements of the Russian and foreign pharmacopoeias for the limits of heavy metals and arsenic in HMPs. National and regional pharmacopoeias have limits for the content of the major toxic elements (lead, cadmium, mercury, chromium, and arsenic) in HMPs. The study showed that the Indian and Japanese pharmacopoeias include only semi-quantitative methods for determination of heavy metals and arsenic, while the Russian and Chinese pharmacopoeias allow for the use of both quantitative and semi-quantitative methods. It was demonstrated that the limits for heavy metals and arsenic are the same for herbal substances and HMPs. The development of consistent approaches to determination of heavy metals and arsenic content, a systematic transition to quantitative methods of analysis, and establishment of individual limits for toxic elements in different HMP dosage forms, will make it possible to achieve the so-called consistent harmonisation, ensure reliable assessment of the content of heavy metals and arsenic, and minimize the risk of their entering human body with HMPs.

The article provides the results of a comparative analysis of requirements laid out in the State Pharmacopoeia of the USSR, XI ed. (SPh XI) and the State Pharmacopoeia of the Russian Federation, XIII ed. (SPh XIII) concerning  quality evaluation and standardization of herbal substances, herbal medicines and other herbal products. The article discusses requirements  for the criteria of herbal substances and herbal medicines quality control described in general chapters and monographs that were previously in force and that have recently been adopted. The article mentions new herbal substances that were included into the State Pharmacopoeia of the Russian Federation for the first time as well as herbal substances included into the State Pharmacopoeia of the USSR, X ed., not included into SPh XI, but included into SPh XIII. The article analyses the requirements described in the new general chapters that were recently included into SPh XIII: “Herbal substances. Herbal preparations”, “Determination of heavy metals and arsenic content in herbal substances and herbal medicinal  products”, “Determination of water absorption  factor for herbal substances”,  “Buds”, “Cut-pressed granules”. The article suggests ways to improve methods of analysis of herbal substances and herbal medicinal products in view of recent advances in pharmacopoeial analysis and the increasing requirements for its quality.
