Abstract
In this exploration of Curcuma longa Linn., commonly known as turmeric, renowned for its therapeutic history, our study focuses on the bioactive compound curcumin. We established and validated an HPLC method for precise curcumin quantification, complemented by an examination of total phenolic and flavonoid content, as well as antioxidant capabilities in a methanolic extract from C. longa rhizomes obtained through a methanol-based Soxhlet extraction. The HPLC analysis utilized a C18 column with a mobile phase of 70:30 V/V Acetonitrile (ACN) to Water (with 1% Glacial Acetic Acid) under an isocratic elution at 1 mL/min, detection at 420 nm, and a reference standard. The method exhibited notable accuracy, precision, and reproducibility. Antioxidant potential, assessed through DPPH, nitric oxide, and hydroxyl radical scavenging assays, unveiled significant total phenol and total flavonoid quantities, highlighting C. longa's potent antioxidant capacity. The study demonstrated a correlation between antioxidant activities and phenolic and flavonoid concentrations, reinforcing the robustness of our method. In conclusion, this method offers an effective means of quantifying curcumin within C. longa rhizomes and holds promise as a valuable tool for maintaining quality control in the production of this botanical material.

Abstract
Curcuma longa L. and Plumbago zeylanica L. are renowned for their antioxidant, anti-inflammatory, and wound-healing properties, primarily attributed to their polyphenolic compounds. However, the limited water solubility of these compounds poses challenges to their effective utilization. Encapsulation within phytosomes offers a solution by enhancing bioavailability and permeability. This study aimed to formulate a phytosome-based polyherbal gel incorporating methanolic extracts of P. zeylanica and C. longa to explore its potential in wound healing. Methanolic extracts of P. zeylanica roots and C. longa rhizomes were encapsulated in phytosomes using the lipid film hydration technique. Various phytosome formulations were developed and characterized for encapsulation efficiency, particle size, polydispersity index and zeta potential. The optimized phytosomal dispersion (F7) was integrated into a carbopol-based hydrogel matrix. In vitro release studies demonstrated prolonged release compared to conventional forms. Stability testing confirmed the robustness of the phytosomal gel at 4 °C/60 ± 5% RH. Wound healing activity was assessed using an excision wound model. The phytosomal gel exhibited enhanced wound contraction and reduced epithelization time compared to conventional gel and control groups, signifying its potent wound-healing effect. In conclusion, the polyherbal phytosomal gel, incorporating P. zeylanica and C. longa, holds promise in promoting wound healing, presenting a novel and effective approach in the realm of topical formulations for wound care.

Abstract
Curcumin (CU) is a polyphenolic compound extracted from turmeric, a well-known dietary spice. Since it has been shown that CU exerts beneficial effects on human health, interest has increased in its use but also in its analysis in different matrices. CU has an antioxidant character and is electroactive due to the presence of phenolic groups in its molecule. This paper reviews the data reported in the literature regarding the use of electrochemical techniques for the assessment of CU antioxidant activity and the investigation of the voltammetric behavior at different electrodes of free or loaded CU on various carriers. The performance characteristics and the analytical applications of the electrochemical methods developed for CU analysis are compared and critically discussed. Examples of voltammetric investigations of CU interaction with different metallic ions or of CU or CU complexes with DNA as well as the CU applications as electrode modifiers for the enhanced detection of various chemical species are also shown.

Abstract
Lakadong turmeric has been outlined for its high content of curcuminoids across the globe. Three significant molecular markers are widely present in turmeric viz, curcumin, desmethoxycurcumin, and bisdemethoxycurcumin, and they are present very high amount in Lakadong turmeric. Curcuminoids have been reported for structural and spectrum similarity of 3 to 4 nm (432, 434, and 436 nm, respectively). Current purification methods are based on recrystallisation where it is difficult to get highly pure material and preparative methods associated with tedious separation with high cost. Lakadong turmeric has not been explored commercially since long time. No reports are available in the literature with highly pure reference materials with in-depth characterization data and purity assessment. Curcumin, desmethoxycurcumin, and bisdemethoxycurcumin were characterized using different analytical techniques viz, UV-Visible Spectroscopy, Fourier Transform Infrared Spectroscopy (FT-IR), Differential Scanning Calorimetry (DSC), Thermogravimetric Analysis (TGA), Proton Nuclear Magnetic Resonance (1HNMR), Carbon-13 Nuclear Magnetic Resonance (13CNMR), High-Resolution Mass Spectrometry (HR-MS) and Inductive Coupled Plasma Mass Spectrometry (ICP-MS). Purified 3 markers has shown High-Performance Liquid Chromatography-Diode Array Detector (HPLC-DAD) purity more than 99.5%. DSC the melting peaks of curcumin, desmethoxycurcumin and bisdemethoxycurcumin were observed at 168 °C, 165 °C, and 210 °C, respectively. These plant-based markers have high commercial potential as reference material for routine Quality Assurance and Quality Control (QAQC) in herbal industries.

Abstract
Curcumin is the principal curcuminoid found in the rhizomes of turmeric. Due to its therapeutic action against cancer, depression, diabetes, some bacteria, and oxidative stress, it has been used widely in medicine since ancient times. Due to its low solubility, the human organism cannot completely absorb it. Advanced extraction technologies, followed by encapsulation in microemulsion and nanoemulsion systems, are currently being used to improve bioavailability. This review discusses the different methods available for curcumin extraction from plant material, methods for the identification of curcumin in the resulting extracts, its beneficial effects on human health, and the encapsulation techniques into small colloidal systems that have been used over the past decade to deliver this compound.

Study of chloroquine susceptibility potential of plants using pseudomonas aeruginosa as in vitro model. 3 Biotech 2022; 12:329. [PMID: 36285247 PMCID: PMC9587148 DOI: 10.1007/s13205-022-03382-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2022] [Accepted: 09/26/2022] [Indexed: 11/05/2022] Open
Abstract
Chloroquine (CQ) is mainly known for antimalarial activity but due to lower sensitivity, it has not been well explored in the microbial disease treatment. In the present investigation, we attempted to enhance the CQ sensitivity in Pseudomonas aeruginosa. Presence of efflux pump is well demonstrated in bacterial system which plays an important role in drug sensitivity and resistance in bacteria and also serves other functions. Taking the advantage of presence of efflux pump in Pseudomonas aeruginosa, we made an attempt to sensitize the Pseudomonas aeruginosa with various plant extracts and phytochemicals for the development of CQ sensitivity. Ten rationally selected plant extracts were screened for the development of chloroquine sensitivity in P. aeruginosa. The chloroquine susceptibility assay was demonstrated by combining CQ and verapamil (a known efflux pump inhibitor) as a standard in an in vitro assay system. Results were quite encouraging as methanolic extracts of Syzygium aromaticum, Zingiber officinale and Curcuma longa were able to enhance chloroquine sensitivity in P. aeruginosa by increasing the zone of inhibition in well-defined assay system. These plant extracts were finally analysed for the presence of various phytochemicals. The Syzygium aromaticum extract showed the presence of phytochemicals, such as quinones, phenol, triterpenoid, saponins, tannins, alkaloids and flavonoids. On the other hand, the methanolic extract of Zingiber officinale and Curcuma longa showed the presence of saponins, tannins, alkaloids and flavonoids in the extract. Towards the identification of active principle of selected plant extract for CQ sensitivity enhancement, thin-layer chromatography was performed and various phytocomponent bands were isolated. Flavonoid (Rf 0.44) in Syzygium aromaticum, alkaloid (Rf 0.43) in Zingiber officinale and phenol (Rf 0.62) in Curcuma longa were found responsible for the enhancement of CQ susceptibility in P. aeruginosa. This interesting finding confirmed the concept that a prior course or combination of plant extracts or phytochemicals with chloroquine can be effective against P. aeruginosa. Present investigation successfully presented the proof of concept for the enhancement of chloroquine sensitivity in bacterial system by modulating an efflux pump. Concept can be explored for repurposing chloroquine for new applications.

Abstract
Curcumin (1,7-bis-(4-hydroxy-3-methoxyphenyl)-hepta-1,6-diene-3,5-dione) is a natural lipophilic polyphenol that exhibits significant pharmacological effects in vitro and in vivo through various mechanisms of action. Numerous studies have identified and characterised the pharmacokinetic, pharmacodynamic, and clinical properties of curcumin. Curcumin has an anti-inflammatory, antioxidative, antinociceptive, antiparasitic, antimalarial effect, and it is used as a wound-healing agent. However, poor curcumin absorption in the small intestine, fast metabolism, and fast systemic elimination cause poor bioavailability of curcumin in human beings. In order to overcome these problems, a number of curcumin formulations have been developed. The aim of this paper is to provide an overview of recent research in biological and pharmaceutical aspects of curcumin, methods of sample preparation for its isolation (Soxhlet extraction, ultrasound extraction, pressurised fluid extraction, microwave extraction, enzyme-assisted aided extraction), analytical methods (FTIR, NIR, FT-Raman, UV-VIS, NMR, XRD, DSC, TLC, HPLC, HPTLC, LC-MS, UPLC/Q-TOF-MS) for identification and quantification of curcumin in different matrices, and different techniques for developing formulations. The optimal sample preparation and use of an appropriate analytical method will significantly improve the evaluation of formulations and the biological activity of curcumin.
