Isolation of a number of bioactive compounds from medicinal plants such as acetylcholinesterase inhibiting steroidal alkaloids, homomoenjodaramine and moenjodaramine from Buxus hyrcana, anti-epileptic terpenoids delphadienones I and II from Delphinium denudatum, and potent leishmanicidal compound ajoene from Allium sativum have been achieved through bioactivity-guided isolation.

Louis Pasteur was the first to describe the antibacterial effect of onion and garlic juices. Historically, garlic has been used worldwide to fight bacterial infections. Allium vegetables, particularly garlic (Allium sativum L.) exhibit a broad antibiotic spectrum against both gram-positive and gram-negative bacteria. Noteworthy results published include the following: 1) raw juice of garlic was...

OBJECTIVE The schistosomicidal properties of garlic (Allium sativum) and onion (Allium cepa) powder were tested in vitro against Schistosoma mansoni miracidia, schistosomula, cercaria and adult worms. Results indicate their strong biocidal effects against all stages of the parasite and also show scavenging inhibitory effect on 2,2-diphenyl-1-picrylhydrazyl (DPPH) and nitric oxide (NO). MATERI...

Application of most antibiotic growth promoters as feed additives has been banned in a lot of countries due to cross-resistance against pathogens and residues in tissues. Therefore, scientists are searching for alternatives to antibiotics nowadays. Medicinal plant extracts are one of the alternatives that have anti-microbial and growth promoting effect on poultry. In this paper, the benefits of...

Thirty strains of mycobacteria, consisting of 17 species, were inhibited by various concentrations of garlic extract incorporated in Middlebrook 7H10 agar. The concentration required ranged from a low of 1.34 mg/ml to a high of 3.35 mg/ml of media. When there were multiple strains of a species, a mean inhibitory concentration was determined for that species. Six strains of Mycobacterium tubercu...

background & aim: allium sativum commonly known as garlic is an herb used over years to prevent from various ailments such as cardiovascular diseases, cognitive disorders and also enhances the immune system. the aim of the present study is to study the in vitro antiarthritic and antihemolytic potential of garlic in aqueous and methanolic extracts. fourier transform infrared spectroscopy was per...
