The present study aimed to understand, phytochemistry and antioxidant property of five members belonging to Apocynaceae, Catharanthus roseus (L) G. Don; Plumeria alba L.; Pentalinon luteum (L) B. F. Hanson & Wunderlin; Rauvolfia tetraphylla L and Nerium oleander L. The preliminary phytochemical analysis was carried out using the methanolic extract for protein, carbohydrate, alkaloids, phenol, tannin flavonoids, and saponin. They were quantified using spectrophotometer using different standards and methods like the Bradford method using BSA as standard for protein, phenol-sulphuric acid method using glucose as standard for carbohydrates, Folin-Ciocalteau method by Sidduraju and Becker for phenol using catechol as standard, tannins using Folin-Ciocalteu method using tannic acid as standard, Zhishen et al., modified method for flavonoids using quercetin as standard. Total alkaloids were estimated using the dry weight method. Antioxidant properties were studied using the ability of the Soxhlet extracts of the plant samples to scavenge the DPPH radicals using Blois method with modifications. The highest concentration for protein was found in Rauvolfia tetraphylla, and the lowest concentration was found...

Rheumatoid arthritis is an autoimmune disease that involves inflammation of joints. Diclofenac diethylamine, as well as Curcumin, are widely used for symptomatic relief of pain and inflammation. The present study was aimed at providing a simple, accurate and economical spectrophotometric method for simultaneous determination of curcumin and diclofenac diethylamine from topical gel formulation. Simultaneous determination of both drugs namely, curcumin and diclofenac diethylamine was done by Absorbance correction method using phosphate buffer 5.5: ethanol (1:1) as the solvent. A topical gel containing curcumin microspheres and diethylamine were prepared using carbopo l971 as a gelling agent along with propylene glycol, preservatives, and triethanolamine. Diclofenac diethylamine showed an absorbance maximum at 278 nm whereas curcumin showed at 428.4 nm in phosphate buffer 5. 5: ethanol (1:1). The linearity of both drugs was found in the concentration range 2-26 μg/ml for Diclofenac diethylamine and 1-7 μg/ml for Curcumin respectively. This method was then applied successfully to pharmaceutical dosage form gel and no interference of excipients was found. Recovery for curcumin and diclofenac...

Chemically, rhein is 9, 10-Dihydro-4, 5-dihydroxy-9, 10-dioxo-2-anthracenecarboxylic acid, and use as an intermediate to synthesize diacerein which widely used in the treatment of degenerative diseases like, osteoarthritis, osteoporosis, and rheumatoid arthritis and hence has commercial importance. Rhein occurs in free state in nature in different plant families like Cassia, Rhamnus, and Rheum but in very less concentration and as it is currently subject of interest because of its anti-tumor, anti-viral and anti-oxidant properties, therefore, there is need for simple and efficient isolation and extraction method to obtain rhein from available indigenous plant sources. A modified method developed for the isolation of rhein from Cassia angustifolia leaves is described, the method involves oxidative hydrolysis of sennoside with help of an oxidizing agent followed by the isolation of the rhein from reaction mixture, and with substantial yield improvement is achieved. The objective of this study to optimize yield of the rhein from senna semisynthetically. The isolated rhein was analyzed by spectral analysis for its...

The objective of the present study is to develop, evaluate and compare potent phytoconstituents of curcumin loaded solid lipid nanoparticles (CUR-SLN) and Paclitaxel loaded solid lipid nanoparticles (PTX-SLN) for the treatment of malignancy. Curcumin is an active phenolic compound of Curcuma longa as a promising phytoconstituent has been extensively studied over the past several years. The result of these studies has indicated that the curcumin (CUR) acts on multiple molecular targets to selectively kill tumor cells with low intrinsic toxicity. The well-known anticancer agent Paclitaxel (PTX) is used for its effectiveness in the treatment of a wide range of tumors cells. However, due to the hydrophobic nature of PTX limits its effective application as anticancer drug. This study utilizes the immense potential of nanotechnology, particularly SLNs, in improving safety & bioavailability of CUR and PTX. SLN was chosen due to their excellent lipoidal drug carrier properties, physiological compatibility, and economic standpoint. In this study physical mixture of CUR-SLN and PTX-SLN formulation and PTX-SLN formulation were examined on Ehrlich ascites...

Rice (Oryza sativa L.) is one of the most important cereal crops consumed in Asia and the primary staple food being consumed by nearly half of the world’s population. Black rice is getting popular recently and is consumed as a functional food. Black rice contains relatively high anthocyanin in the pericarp layer which gives the dark purple color. Black rice has a higher content of phenolic compounds as compared to white rice. The total phenolic content was four times higher in pigmented rice than in non-pigmented varieties. Heat Moisture Treatment (HMT) and enzymatic modification are essential processes prior to absorption in the human body as they affect digestibility. On the basis of these considerations, the dual modification applied in this study was a combination of heat-moisture treatment (HMT) and enzymatic modification. The samples used for the study were native and dual modified rice flour of selected white and black rice variety. The samples were termed as Native White Rice Flour (NWRF), Dual Modified White Rice Flour (DMWRF), Native Black...
