Medicinal plants, herbs, spices, and herbal remedies are integral components of the alternative system of medicine since while’s ancient Cassia auriculata Linn is a potential folklore medicinal plant (Caesalpiniaceae) used for Ayurveda and Siddha systems of medicine. Plants contain a wide variety of phytochemical constituents, which are secondary metabolites and are used either directly or indirectly in the pharmaceutical industry. For centuries, man has effectively used various components of plants or their extracts for the treatment of many diseases. The aim of the study was to investigate the phytochemical compounds of Cassia auriculata and GC-MS analysis. The presence of phytochemical compounds was screened by a qualitative method using gas chromatography and mass spectroscopy (GC-MS). An aqueous and ethyl acetate extract obtained were subjected to GC-MS for the determination of bioactive volatile compounds. GC-MS analysis was carried out using claries 680 GC with clarus 600 (EI) MS. The GC-MS analysis of the aqueous and ethyl acetate extract revealed the presence of 26 bioactive compounds with valuable biological activities. The major...

Nanotechnology can be applied to deliver and protect antioxidants in order to control the oxidative stress phenomena in several chronic pathologies. Chitosan (CS) and its carboxymethyl derivatives are smart biopolymers that are non-toxic, biocompatible, and biodegradable, and, hence, suitable for various biomedical applications, such as drug delivery gene therapy and tissue engineering. Vitis vinifera (VV) seeds are the major chemotherapeutic agent with antioxidant, anti-inflammatory, antiproliferative, anticancer, and antimicrobial effects. However, the potential of these leaves as a chemotherapeutic agent is limited by their hydrophobicity and poor bioavailability. The chitosan tripolyphosphate (CS/TPP) nanoparticles have been used in this study as an alternative to encapsulate bioactive flavonoids from ethanolic extract of Vitis vinifera seeds. The Vitis vinifera seeds extract-loaded CS (CS-VVE) nanoparticles were characterized using FT-IR. The Zeta sizer and zeta potential confirmed that the particle has 216nm and 50.3mV. This study also found that the CS-VVE NPs shown anticancer activity in human colon cancer cell lines should be explored further for Cytotoxicity studies using MTT assay and tested drug-induced apoptotic...

The objective of the research work was to design NLCs gel of Acitretin and perform an in-vitro evaluation of different formulations. FTIR and DSC studies revealed that there was no interaction between drug and polymer and with the respective surfactant. A new generation of NLCs consisting of a lipid matrix with a special nanostructure has been developed. These nanostructures improve drug loading and firmly incorporates the drug during storage. The purpose of this study was to prepare Acitretin-loaded NLCs gel effective for topical delivery of Acitretin by using the Hot Homogenization method. Stearic acid as solid lipid, Oleic acid as liquid lipid combination of two types of surfactant: Tween 80 and Sodium lauryl sulphate (SLS) were used to stabilize NLCs dispersion. Physiochemical properties of NLCs gel such as particle size, TEM, entrapment efficiency, and in-vitro release studies were investigated. The formulation in which a combination of ionic and non-ionic surfactant was used to demonstrated good entrapment efficiency, sustained in-vitro release profile. In-vitro release study revealed the biphasic release pattern...

Ganoderma lucidum total triterpenes were evaluated for anti-inflammatory activity using carrageenan-induced acute and formalin-induced chronic paw oedema models in Swiss albino mice. The total triterpenes, at concentrations 10, 50, and 100 mg/kg b. wt. administered orally, showed 36.96%, 54.35%, 76.09% inhibition of acute and 41.86%, 62.79% and 79.07% inhibition of chronic inflammation. Total triterpenes were also assessed for its effect in attenuating the inflammation and modulating the antioxidant status of Freund’s complete adjuvant (FCA) induced arthritis rats. Total triterpenes when administrated orally, at concentrations 10, 50, and 100mg/kg b. wt., showed 58.73%, 73.02%, and 79.37% inhibition of paw oedema in the arthritis rats. Treatment with total triterpenes enhanced the activities of the antioxidant enzymes (SOD, GPx, and catalase) and restored the level of GSH in arthritic animals. Total triterpene treatment also attenuated the enhanced lipid peroxide levels in FCA-induced rats. All these findings support the strong therapeutic potential of Ganoderma total triterpenes against inflammation...

Apremilast, the new PDE4 inhibitor drug, exhibits low solubility and low permeability; therefore, shows variable bioavailability. Effervescent floating tablets of apremilast were developed to sustain the drug release rate by increasing gastric retention time. These tablets were prepared by wet granulation technique, using different polymers like carbopol 934P, hydroxypropyl methylcellulose K4M, tragacanth and sodium alginate, either alone or in combination. Prepared tablets were characterized for physical parameters like floating capacity, hardness, % weight variation, friability, and content uniformity. Additionally, tablets were evaluated for in vitro release characteristics for 24 h. Results of this study exhibited good physical properties within the limit of acceptance. Batches prepared by carbo-pol 934P did not show any initial burst release as compared to other polymers. When polymer concentrations were increased drug release rate was decreased. Drug release from the tablets was followed by zero-order controlled release. Sodium alginate/ tragacanth and HPMC K4 in 1:3 ratio exhibited best drug release for 24 h. Carbopol batches (1:3 ratio ) showed very first floating lag time (52...
