In vitro effect of azadirachtin-A, a tetranortritarpinoid of neem seed kernel, on rat spermatozoa
Since, there is only few documented evidence referring to assessment of the clear specific actions of medicinal plant source or active constituents in rodent model, the present study is undertaken to evaluate the effective concentration of technical azadirachtin-A, a tetranortritarpinoid of neem seed kernel, to immobilizes the cauda epididymal spermatozoa within 20 seconds and effectively inhib...
متن کاملSpecies Sensitive Electrochemical Method for Enrichment of Azadirachtin-A from Neem Seed
Azadirachtin the active principle of Azadirachta-indica J. Juss. (Neem) ranges from 0.3 to 0.6 percent. A simplified procedure, when compared to established methods, has been developed to enrich azadirachtin-A to 50 percent using minimum possible steps without resorting to chromatographic techniques. It involves additional partition with CCl4 before final extraction which removes most of nimbin...
متن کاملEvaluation of the composition of Carica papaya L. seed oil extracted with supercritical CO2
Among the most important tropical fruit grown in the world today and in Brazil, papaya occupies a prominent place. Native to tropical America, papaya has spread to several regions of the world, and Brazil accounts for 12.74% of the world production, followed by Mexico, Nigeria and India. The culture reached a harvested area of 441,042 ha and production of 12,420,585 t worldwide. The largest int...
متن کاملSeparation of phenolic compounds from plant materials using supercritical CO2
In the present work supercritical fluid extraction (SFE) using CO2, was applied for the pre-treatment of mandarin peels. Two-step extraction, combining SFE and conventional extraction, was investigated. During the first extraction step supercritical CO2 at temperatures 25, 40 and 60°C and pressures from 100 to 300 bar was applied to remove the non-polar components from the extracting material. ...
متن کاملMeasurement and Modeling of Acridine Solubility in Supercritical Carbon Dioxide
Supercritical carbon dioxide has gained increasing attention in food and pharmaceutical processing owing to the fact that it is environmentally inexpensive, not flammable, essentially non-toxic, and it has a convenient critical point. Also, it has been attracting much attention in many fields, such as extraction of sensitive materials and pharmaceutical processing and polymerization processes. ...
