The aim of this study was to determine the qualitative and quantitative phytochemicals Napoleona imperialis stem bark. Methods: Extractions Phytochemical analysis bark were done using standard procedures. Result: Aqueous extract had yield 76.9g (7.69%) methanol also yielded 58.5g (5.85%) when 1000g pulverized used for each. Qualitative phytochemical exhibited moderate quantities alkaloid, stero...

Ultrasound and microwave techniques were used to extract tobacco alkaloids, and response surface methodology was used to optimize extraction conditions. Ultrasonic technique factors were temperature, 30-85 degrees C; time, 3-45 min; solvent volume, 8-80 mL. Microwave extraction factors were pressure, 15-75 psi; time, 3-40 min; power, 30-90% of the maximum magnetron power of 650 W. Soxhlet and s...

Elettaria cardamom (Alaichi) is a spice available in Nepal, from the bark of which alkaloid can be extracted to use as corrosion inhibitor. The inhibition methanolic extract (EC) for mild steel (MS) 1M H2SO4 was studied using weight loss method. effect time immersion and concentration EC on investigated. result showed that efficiency increased with an increase extract. maximum 1000 ppm 93.36% 3...

The present study was aimed to evaluate the phytochemical, antidiabetic, and cytoprotective properties of Berberis aristata DC. (Berberidaceae) root extracts. After phytochemical evaluation of various extracts of B. aristata roots, the ethanol extract was found to be rich in phytochemicals with the presence of alkaloid determined by the thin layer chromatography; hence ethanol extract was selec...

Papaya leaves have a number of alkaloid compounds (carpaine, pseudocarpaine, dehydrocarpaine I, dehydrocapaine II and emetine. Carpaine is piperidin alkaloid. The activity antiplatelet. This study aims to determine the antiplatelet papaya leaf extract againts male mice. Desain this research pure experimental with pre test – post control group design. Subjects consisted 4 groups mice each 5 was ...

Two tetrahydroisoquinoline alkaloids were extracted from the alkaloid fraction of a methanol extract of the seeds of Calycotome Villosa Subsp. intermedia. Their structures were established as (R)-1-hydroxymethyl-7-8-dimethoxy-1,2,3,4-tetrahydro- isoquinoline (1) and (S)-7-hydroxymethyl-2-3-dimethoxy-7,8,9,10-tetrahydroisoquinoline chloride (2) by spectroscopic techniques and X-ray diffraction a...

A new pentacyclic stemona alkaloid, stemocurtisine (2), with a novel pyrido[1,2-a]azapine A,B-ring system, has been isolated from a root extract of Stemona curtisii. The structure and relative stereochemistry was determined by spectral data interpretation and X-ray crystallography.

Four alkaloids, annocherine A, annocherine B, cherianoine, and romucosine H, along with one known alkaloid, artabonatine B, were isolated from the MeOH extract of the stems of Annona cherimola. Their structures were identified on the basis of both analysis of their spectral data and from chemical evidence.

opium poppy (papaver somniferum l.) has two major products: alkaloids in the capsules and the seeds. it is known that opium poppy today contains alkaloid in great quantities. opiate alkaloids and their synthetic derivatives are widely used in medicines which are produced in hundreds of tons for the medicine industry. the study aimed to screen the capsules of six turkish opium poppy lines to eva...

The seeds of Lupinus termis are used in the Middle East and Africa as food and in folklore medicine. In traditional medicine, the seeds are reputed to be effective for diabetes. Topically, the powdered seeds are used to treat acne, and in clinical studies performed outside the U.S.A., the ethanolic extract demonstrated efficacy in the treatment of chronic hand and foot eczema. In order to evalu...
