Variation of ursolic acid content in eight Ocimum species from northeastern Brazil.

Quantification of betulinic, oleanolic and ursolic acids as medicinally important triterpenoids in some Thymus species from Iran

Background and objectives: Betulinic acid (BA), oleanolic acid (OA) and ursolic acid (UA) are well-known pentacyclic triterpenoids (PTs), which are produced by plants. They possess a variety of beneficial effects including anti-inflammatory, hepatoprotective, antitumor, anti-HIV, antimicrobial, gastroprotective, and antihyperlipidemic activities. In the present study, quantitative determination...

Chemical composition and antimicrobial activity of essential oils of Ocimum canum Sims. and Ocimum selloi Benth.

This work describes the chemical composition and antimicrobial activity of the volatile oils of Ocimum canum and Ocimum selloi, both occurring in Jequié/BA, northeastern Brazil. The plants were collected in the winter/2005 and summer/2006, the oils extracted by steam distillation and further analyzed by GC-MS. A total of 30 and 31 compounds was identified from the oils of O. selloi and O. canum...

A Study on the Effect of Ocimum sanctum (Linn.) Leaf Extract and Ursolic Acid on Spermatogenesis in Male Rats

Rapid identification of molecular changes in tulsi (Ocimum sanctum Linn) upon ageing using leaf spray ionization mass spectrometry.

Tulsi or Holy Basil (Ocimum sanctum Linn) is a medicinally important plant. Ursolic acid (UA) and oleanolic acid (OA) are among its major constituents which account for many medicinal activities of the plant. In the present work, we deployed a new ambient ionization method, leaf spray ionization, for rapid detection of UA, OA and their oxidation products from tulsi leaves. Tandem electrospray i...

Ocimum Sanctum Linn. (holy Basil): Pharmacology behind Its Anti- Cancerous Effect

Presently, researchers have been given remarkable attention to complementary and alternative medicine to deal with cancer treatment from medicinal plants mainly due to its fewer side effects and ease availability. Several scientific studies deeprooted the anticancerous property of Ocimum sanctum Linn., a traditional medicinal plant commonly known as Tulsi. The chemopreventive and radiopreventiv...
