Catharanthus roseus is an important medicinal plant, which produces a variety of indole alkaloids of significant pharmaceutical relevance. In the present study, we aimed to investigate the potential stress-induced increase of indole alkaloid biosynthesis in C. roseus using proteomic technique. The contents of the detectable alkaloids ajmalicine, vindoline, catharanthine, and strictosidine in C....

Kodiveli is an important Siddha drug used in the formulations such as Podi, Ennai, Thylam, Chithramoola Kuligai and Kudineer. The HPTLC a simple method to differentiate closely related species. profiling of ethanolic extracts roots three species Plumbago (Plumbago zeylanica L. (Venkodiveli), P.indica L., (Senkodiveli) P. auriculata Lam. (Karunkodiveli)) has been carried out using Toluene: Ethyl...

The Plumbago genus belongs to the Plumbaginaceae family and it is known due to its variety of biological uses, most of them attributed to the presence of naphthoquinones. Plumbagin is a naturally occurring naphthoquinone that can be obtained from roots of Plumbago scandens L. In order to find out the better technique for plumbagin extraction, were applied: static maceration, dynamic maceration,...

Plumbago scandens L. is a Brazilian tropical/subtropical species that occurs along the coast. Chemically it is mainly represented by naphthoquinones, flavonoids, terpenoids and steroids. The aim of the present work is to study quantitative changes in the root metabolic production of Plumbago scandens during different physiologic developmental stages relative to floration. The results indicated ...

OBJECTIVE To develop a simple rapid procedure for bioreduction of silver nanoparticles (AgNPs) using aqueous leaves extracts of Catharanthus roseus (C. roseus). METHODS Characterization were determined by using UV-Vis spectrophotometry, scanning electron microscopy (SEM), energy dispersive X-ray and X-ray diffraction. RESULTS SEM showed the formation of silver nanoparticles with an average ...

The effect of phonophoresis was assessed using Frund’s complete adjuvant (FCA) induced arthritis in rats. Plumbago zeylanica (0.5g) root extract was prepared to obtain 0.5% gel. The animals were divided into four groups. Group I serves as normal. Group II to IV served as arthritis animals induced by FCA. Group III and IV treated with ultrasound and phonophoresis (Application of ultrasound along...

Abstrak : Tapak dara (Catharanthus roseus)merupakan obat tradisional, dimana ekstrak baik dari daun ataupn bunga digunakan sebagai oleh masyarakat pedesaan. Perlu dianalisis sifat gel etanol yang dihasilkan yaitu penampakan etanol, viskositas, uji pembakaran, nilai kalor, panas dipindahkan, dan analisis warna api sehingga bisa kelihatan sediaan terbaik untuk menghasilkan etanol. Penelitian bers...

Forty five plumbago rosea accessions collected from different parts of Kerala state were evaluated for variability in morphological and yield related characters and plumbagin content. Highly significant variation was evident for all the characters studied except leaf size indicating wide variability in the accessions. Accessions PR 25 and PR 31 appear to be promising with respect to root yield ...
