Curcumin, a natural compound extracted from turmeric (Curcuma longa), has been extensively studied because of its various pharmacological properties, such as anti-inflammatory, antioxidant, antibiotic, antiprotozoal, immunomodulatory, anti-proliferative, antitumor, and anticarcinogenic effects. However, low solubility in aqueous media has limited its therapeutic applications. To overcome these bioavailability issues, the use of drug delivery systems providing localized or targeted delivery of this drug may represent a more viable therapeutic option. Several drug delivery systems have been shown to significantly enhance the therapeutic efficacy of curcumin. Additionally, a wide variety of analytical methods are available for the qualitative and quantitative analysis of curcumin in different matrices, including plant extracts, biological fluids, and drug delivery systems. There are a variety of methodologies to quantify curcumin, but chromatographic and spectroscopic techniques are th...
A comprehensive review on physicochemical, pharmacological and analytical profile of curcumin
International Journal of Research in Pharmaceutical Sciences, 2021
In the rhizomes of curcuma longa (family zinziberaceae), curcumin is present as a pigment, due to which it has importance in spices, cosmetics and drugs. It shows a variety of biological and physiological activities, like anti-tumour, anti-inflammatory, antiviral, anti-oxidant, anti-HIV etc. It has low toxicity at higher doses and is well tolerated by the human body. In spite of the proven research that supports the medicinal benefits of curcumin, its medicinal uses are countered by its low aqueous solubility and potential to get degraded in the GIT, which ultimately contributes towards its poor bioavailability. The present review summarizes the uses and applications of curcumin in drugs and cosmetics, briefly describing its status in folk medicines. It also mentions the methods of its analysis in drugs and cosmetics formulations and foodstuffs. The use of turmeric in ayurvedic medicines is described with their recipe and references.

Curcuma longa (Turmeric) is used successfully in Ayurvedic formulations from ancient times. It is a rich source of bioactive phytoconstituents like curcuminoids, turmerone and many more. Curcuminoids is the group of chief dynamic components and has number of medicinal uses such as anti-inflammatory, anti-HIV, antitumour, antiviral, anticancer, antifungal and antiparasitic. Different analytical methods have been developed in recent year for the quality control analysis of curcuminoids in Curcuma longa extract including HPLC, HPTLC and UV-Visible Spectrophotometry. While the primary component curcumin from curcuminoids is still lacking for its analytical method development along with validation. Therefore, in the present study, a simple UV visible and HPLC method was developed and validated according to international conference harmonization (ICH) guidelines for the quantitative estimation of curcumin in Curcuma longa extract.

The developed method was validated in accordance with the international conference on harmonization (ICH) guidelines. The developed method was implemented to estimate the amount of curcumin in the curcumin-nanoparticulate formulation. Results: The optimum chromatographic conditions with adequate resolution for curcumin (16.10 min) was achieved when the separation was carried using C18 Conclusion: The developed analytical method is simple, precise, and reproducible and thus can be used for stability-indicating analysis of curcumin in pharmaceutical formulations. column at ambient temperature with an isocratic elution mode of mobile phase composed of a degassed mixture of phosphate buffer pH 3 and acetonitrile (50:50 v/v) at 1.0 ml/min flow rate with a total run time of 20 min. The developed method was validated for system suitability, accuracy, precision, limit of detection (LOD), limit of quantitation (LOQ), linearity and range. The LOD and LOQ were found to be 0.018 and 0.056 μg/ml respectively, which indicates that the method was sensitive, and can detect and quantify at lower levels of curcumin. Linearity range was from 5-15 μg/ml for curcumin with regression coefficient 0.997 indicates that at this concentration range curcumin was highly linear. Percent assay of curcumin was found to be 98.7% and curcumin recovered was found to be 0.78 mg which are estimated by using the developed method.

Curcumin is a lipophilic compound which suffers from the poor bioavailability after oral administration. Increasing its dissolution rate can be a successful strategy to improve the bioavailability. Along with the formulation developments, a rapid and simple analytical method to determine curcumin concentrations in the dissolution medium is required. The aim of this study was to develop and to validate an analytical method based on thin layer chromatography (TLC) to determine curcumin concentrations in a dissolution medium containing 0.5% w/v sodium lauryl sulfate (SLS) and 20 mM sodium phosphate buffer. A polyvinylpyrrolidone K30 based solid dispersion of Curcuma longa extract and its corresponding physical mixture were dissolved in a medium containing 0.5% w/v SLS and 20 mM sodium phosphate buffer (pH 6.0). Dissolution samples were spotted on a normal TLC plate and eluents of various compositions were evaluated. The retardation factor (Rf), resolution (Rs), and asymmetry factor (As...

International Journal of Pharmacognosy and Phytochemical Research
Curcumin, an important phytoconstituent obtained from Curcuma longa L. (turmeric) is used traditionally in the treatment of various inflammatory diseases like arthritis, stroke and bowel diseases, etc. Despite its many health benefits, instability of curcumin in plasma is a major issue. The retention of curcumin in plasma must be properly evaluated in order to establish its stability in biological systems. The current study presents an HPTLC method undertaken for detection of curcumin and determination of its stability in plasma and different tissues of rats. The plasma and tissue samples were appropriately processed to render them suitable for HPTLC analysis. The method employed HPTLC glass plates precoated with silica gel 60F254 as the stationary phase. The mobile phase developed consisted of chloroform, methanol and glacial acetic acid which successfully gave distinct bands for curcumin with a Rf value of 0.95. This newly developed HPTLC method was found to be reproducible and ac...
Comparison of Analysis Methods for Curcumin Determination: A Literature Review
Medical sains : jurnal ilmiah kefarmasian, 2023
Curcuminoids such as curcumin, demethoxycurcumin (DMC), and bisdemethoxycurcumin (BDMC) are the major bioactive components found in Curcuma species, including turmeric (Curcuma longa L.). Curcumin is a polyphenol that is used as an antioxidant. Various analytical methods have been developed for the detection of curcumin, each with its advantages and limitations. Selection of an appropriate analytical method is crucial for obtaining accurate results. Although critical reviews on the chemical, biological, and pharmacological properties of curcumin are widely available, reviews specifically focusing on the different analytical methods for curcumin are limited. This review article aims to provide an overview of several analytical methods for the determination of curcumin. This is expected to encourage readers to choose a suitable analytical method for their specific needs. The articles used in this review were sourced from international English-language publications obtained from Science Direct, PubMed, and Google Scholar. The search was performed using keywords such as "Instrumental analysis of curcumin" and "Analytical techniques for curcumin analysis." The results reveal that spectrophotometric methods are simple techniques used to estimate curcumin content; however, their utility is limited to cases where the concentration of each curcuminoid is not a critical quality parameter. Accurate quantification and detection of trace amounts of curcuminoids and metabolites require the use of chromatographic separation methods combined with mass spectrometry detection (LC-MS/MS) because of their high accuracy, reproducibility, and sensitivity with low limits of detection (LOD) and lower limits of quantification (LLOQ).
