A green study was undertaken for the extraction of plumbagin, an important natural naphthoquinone, from roots Plumbago pulchella Boiss. In first stage, four solvents were comparatively evaluated, acetone, n-hexane, ethyl acetate, and methanol; attending Principle #5, only (ethyl acetate acetone) underscored. a second step, considering # 6, various alternative activating modes assessed: two elec...

Haematococcus pluvialis is one of the potent organisms for production of astaxanthin. Up to now, no efficient method has been achieved due to its thick cell wall hindering solvent extraction of astaxanthin. In this study, four different methods, hydrochloric acid pretreatment followed by acetone extraction (HCl-ACE), hexane/isopropanol (6:4, v/v) mixture solvents extraction (HEX-IPA), methanol ...

Peltophorum africanum (Fabaceae) is a deciduous tree widespread in southern Africa. The plant has many ethnomedical and ethnoveterinary uses. Root and bark decoctions are used to treat diarrhoea, dysentery, sore throat, wounds, back and joint pains, HIV-AIDS, venereal diseases and infertility. Pastoralists and rural farmers use the root and bark extracts to treat diarrhoea, dysentery, infertili...

The present study investigated the physicochemical properties and phytochemical constituents of seed oil of Semecarpus anacardium L. to understand its biopesticidal and therapeutic potential. Preliminary phytochemical studies showed the presence of polyphenolic compounds, flavonoids, tannins, saponins, steroids in seed oil which is extracted using various organic solvents such as n-hexane, petr...

A simplified method for the determination of benzylaminopurine in agricultural products by LC/MS was investigated. Benzylaminopurine in agricultural products was extracted with acetone and the extract was concentrated to below 30 mL. Buffer solution of pH 9.0 and ethyl acetate were added to the residue, and the solution was shaken. The ethyl acetate layer was evaporated to dryness, and the resi...

The In vitro antibacterial activity of Leptadenia pyrotechnica roots and fruits extracts was investigated against Staphylococcus epidermidis and S. aureus by using agar-well diffusion assay. Plant samples were collected from Thal desert of Pakistan and eight different solvents viz. n-hexane, chloroform, acetone, ethylacetate, butanol, methanol, ethanol and water were used for the preparation of...

Coriander (Coriandrum sativum) is one of the medicinal plants which known to contain secondary metabolites such as flavonoids, tannins, terpenoids, saponins, steroids, and alkaloids. Alkaloids have therapeutic effects antimalarials cancer. Research in determining alkaloids coriander was carried out by separating from other substances using soxhlet method extraction with two solvents ethanol n-h...

A headspace gas chromatography (HS-GC) method was developed for the simultaneous determination of seven residual solvents (petroleum ether (60-90 degrees C), acetone, ethyl acetate, methanol, methylene chloride, ethanol and butyl acetate) in bovis calculus artifactus. The DB-WAX capillary column and flame ionization detector (FID) were used for the separation and detection of the residual solve...

Ricinus communis has been utilized traditionally as medicine to treat inflammatory related diseases including wounds, sores, and boils. The leaves of R. communis were sequentially extracted with n-hexane, dichloromethane, acetone, and methanol using serial exhaustive extraction method. Antioxidant activity of all crude extracts was quantitatively measured against 2,2'-azino-bis (3-ethylbenzothi...
