As mentioned above 500 glucovance overnight delivery, development of standards for plant-based drugs is a challenging task and it needs innovative and creative approaches glucovance 400 on-line, different from the routine methods [6] buy glucovance 500 cheap. Starting from sourcing of the raw material, standard- ization, preparation of the extracts, to formulation of the extracts into suitable dosage form, the problems vary with each plant species and part of the plant that is being used. At each and every step, phytochemical profles have to be generated and a multiple-marker-based standardization strategy needs to be ad- opted to minimize batch-to-batch variation and to maintain quality and ensure safety and effcacy. Of these, the phytochemical profle is of special signifcance since it has a direct bearing on the activity of the herbal drugs. This is generally because there are a myriad of factors mentioned above that affect the quality of the herbal raw material. The government of India also brought out the Ayurvedic Pharmaco- poeia of India [13]. Kanaki Pharmacopoeias carry monographs for herbs and herbal products to main- tain their quality. Several pharmacopoeias including Indian Pharmacopoeia, European Pharmacopoeia, and British Pharmacopoeia do cover monographs and quality control tests for a few medicinal plants. Over the past 50 years, many changes are being incorporated into the pharma- copoeias, as refected by the availability, development, and subsequent refne- ment of analytical techniques. Although initially most of the aforementioned pharmacopoeias did not describe methods for the phytochemical evaluation of the raw material, more recently, assays of chemical compounds are recom- mended and are being included (e. Plants are complex mixtures of varied chemicals, which pose a problem in stan- dardization and quality control, but that very fact is responsible for imparting them with the feature of being therapeutically effective with the advantage of Chapter 19 Phytochemical Standardization 353 synergistic and additive effects and at the same time having less side effects [20]. Consequently, the herbal drug preparation itself as a whole is regarded as the active substance. Hence, the reproducibility of the total confguration of herbal drug constituents is important. To meet this requirement it is essential to estab- lish the chemoprofles of the samples encompassing the following: 1. Of these, the fngerprint profles serve as guideline to the phytochemical profle of the drug in ensuring the quality, while quantifcation of the marker com- pound/s would serve as an additional parameter in assessing the quality of the sample. Recent advances in chromatographic techniques have enabled reproducible, rapid, and effcient semiquantitative and quantitative analysis of the chemical constituents in complex mixtures [15, 18, 21–25]. Most of the herbal formulations, especially the classical formulations of Ay- urveda and Unani, are polyherbal. Furthermore, the unique processing meth- ods followed for the manufacturing of these drugs turn the herbal ingredients into very complex mixtures, from which the separation, identifcation, and es- timation of chemical components is very diffcult. As in the case of the raw material, parameters can also be defned for polyherbal formulations, where it includes comparison of the phytochemical profle of the formulations with that of individual ingredients (e. However, in case of many other preparations, it is not very easy since the chemical constituents of the herbs undergo complex changes during the unique processing steps involved in traditional preparations (e. In such cases, sample preparation for phytochemical analysis should take into consid- eration the process of preparation of the formulation. Phytochemical standardization encompasses all possible information gener- ated with regard to the chemical constituents present in a herbal drug. Hence, the phytochemical evaluation for standardization purpose includes the following: 1. This is rather diffcult since plants are known to contain many chemical constituents that either directly or indirectly participate in their therapeutic outcome. For sample preparation, some guidance can be taken from the type of extracts used in traditional medicine for each drug. Reports on the pharmacological activity of the specifc plant can also be taken into consideration. The next logical step would be to quantify the major chemical group/s, since this will have a bearing upon the effcacy of the drug. Some examples include total alkaloids [32–35], total phenolics [36], total triterpenic acids [37], and to- tal tannins [38]. Furthermore, pre- or postchromatographic derivatization of the sample with suitable chemical re- agents may be employed for detection of the sample constituents. The potential of the phytochemical profling in quality control can be well appreciated in the reported detailed fngerprint profles generated with or without chemical mark- ers [17, 18, 25, 39]. In this way a lot of information can be generated with re- gard to even the unknown chemical constituents of the drug. The information so generated has a potential application in the identifcation of an authentic Chapter 19 Phytochemical Standardization 355 drug, in excluding the adulterants and in maintaining the quality and consis- tency of the drug [25]. Some examples of reported work include fngerprint profles of oleogum resin of Dorema ammoniacum [25], Rosa damascena [40], Citrus aurantium spp. Such fngerprint profles are usually distinctive and would form a benchmark for the drug, especially when the identity of the active principles is not known or when chemical markers are not available. In this process, it is important to take into account all of the information available in the fngerprint analysis in toto to ascertain the quality of the sample. This phytochemical profle can form an important component of quality-control criteria for herbal drugs.

One absence during the first semester and two absences during the second semester are allowed. In case of further absences practices should be repeated by attending practices of another group on the same week. Requirements for signing the Lecture book: The Department may refuse to sign the Lecture book if the student is absent from practices more than allowed in a semester. Assessment: In the whole year 5 written examinations are held, based on the material taught in the lectures and practicals. At the end of the first semester the written examinations are summarized and assessed by a five grade evaluation. If the student failed - based on the results of written exams - he must sit for an oral examination during the examination period. The student is exempt from written minimum entry test if her/his evaluation based on the 1st and 2nd semester points average is equal to or above 70% of the whole year total points. The final exam at the end of the second semester consists of two parts: a written minimum entry test and an oral exam (1 theoretical, 1 practical topic and 1 practical picture). The practical pictures will be demonstrated on the last lectures of the 2nd semester. Those who fail the minimum entry test, are not allowed to take the oral exam and they have to repeat the minimum entry test part as well. Those who fail the oral exam only, do not have to take the written test on the B or C chance. Requirements for examinations: The examination (written and oral) is based on the whole lecture and practical material (Practicals in Laboratory Medicine, eds.
