The present study was conducted to study optimization of green house conditions for Propagation of Stevia rebaudiana cuttings. Stevia rebaudiana belongs to Asteraceae family and this plant is native to the Brazil and Paraguay. Stevia rebaudiana leaves produces stevioside and rebaudioside. The sweetness of stevioside is 150 -300 times greater than sucrose.Seeds of Stevia are very small in size and infertile and production of Stevia through seeds is not beneficial because seeds are not viable for germination.In present study different concentrations of NAA, IBA, IAA and their combinations were...

Nigella sativa is an annual flowering plant, found in south and southwest Asia. Nigella sativa oil contains conjugated linoleic acid, thymoquinone, nigellone (dithymoquinone), melanthin, nigilline, damascenine, and tannins. In present study, a comparison was made among the extraction efficacy of cold maceration, soxhlet extraction and microwave assisted extraction. Cold maceration of black seeds gave maximum extract after 21 hours of extraction. A maximum of 6.75 g of extract was obtained by soxhlet extraction of Nigella sativa. While Microwaves produced maximum extract (15 g/gram of plant...

In the present study a comparison was made between different extractions methods for anticancer drug Vinblastine from Catharanthus roseus. Extraction was carried out by using two different methods i.e., Microwave Assisted Extraction (MAE) and Soxhlet Extraction using ethanol and a few drops of conc. HCl as an extracting solvent. Estimation of Vinblastine was done by using High Performance Liquid Chromatography (HPLC) by using acetonitrile as mobile phase. Microwave assisted extraction was proved to be a better approach for rapid and efficient extraction of Vinblastine from plant material. It...

Microwave assisted extraction is a modern and novel approach for rapid and efficient extraction of the plant material which are of prime importance in herbal medicinal industry. In present study a comparison was made between conventional method of extraction (stove heating) and the modern method of extraction (Microwave assisted extraction) for analyzing the extraction efficiency of both commonly used methods for household herbal products (i.e., Green tea, Vital tea, Supreme tea, Danedar tea, Tez Dam tea, Tetley and Lipton tea), Qehwa (Peshawari Qehwa), Coffee (Nescafe Classic) and Joshanda...
