“…The alternative use of folkloric medicinal plants detailed their alternative use in medicine in Jamaican society has been studied 7 . The effective inhibition of the growth of some Gram-positive and Gramnegative bacteria by the chloroform and ethyl acetate extracts of Nyctanthes arbortritis fresh flowers has been reported 8 . Datura stramonium is an erect branched undershrub with long white flowers and spiny spherical fruits 9 .…”

Three medicinal plants -Abutilon mauritianum, Bacopa monnifera and Datura stramonium were assessed for phytochemical components and antimicrobial activity. The results revealed that all the three plant extracts contained saponins, tannins and alkaloids. Only Datura stramonium contained glycosides. The plants exert varying inhibitory effects on Pseudomonas aeruginosa, Klebsiella pneumonia and Escherichia coli. The minimum inhibitory concentration of the plant extracts ranged between 10% (w/v) (Bacopa monnifera) and 25% (w/v) (A. mauritianum and D. stramonium). Extracts of Abutilon mauritianum, Bacopa monnifera and Datura stramonium could be potential sources of chemotherapeutic agents.

“…The aim of the present study is to explore Nyctanthes arbor-tristis (Oleaceae) fruits and seeds as a source of melanins. N. arbortristis commonly known as Night Jasmine or Coral Jasmine is used in traditional medicine [7,8]. Previously we reported antibacterial properties of different parts [9], but this is for the first time we report here the isolation of melanins from this plant.…”

Melanin from Nyctanthes arbor-tristis fruits and seeds was isolated and purified by alkaline extraction, acid hydrolysis and organic solvents. Each, fruit and seed yielded melanin 50 mg/100g tissue weight. The melanins of fruit and seeds were analyzed by UV-visible and infrared (IR) spectroscopy for characterization. The IR spectrum of fruit and seed melanins did not match with each other and the seed melanin could be distinguished by their sharp peat at 285 nm from the fruit melanin in IR spectrum. Two melanins have shown absorptions above and below 1600 cm -1 in their respective IR spectrum. The melanins thus characterized were tested for their stability after incubating at different temperatures and in presence of oxidants (KMnO 4 and K 2 Cr 2 O 7 ) and metal ions (Mg ++ and Zn ++ ) for a specified period. The stability of the melanin was assessed by measuring changes in the absorbance at 285 nm. The results revealed that the fruit melanin was more stable at 50 ºC while the seed melanin was quite stable at 25 ºC. However, their stability was markedly affected by oxidants and metal ions.

“…It is mainly characterized by the presence of phenylethanoid derivatives and iridoid derivatives 5 . It is used in traditional medicine as stomachic, carminative, intestinal astringent, expectorant, in biliousness, piles, and various skin diseases and as hair tonic 6 . It has also been reported to possess hepato-protective, anti-viral, antifungal 7 and analgesic, anti-pyretic, ulcerogenic activities 8 .…”

Ayurveda is one of the oldest systems of medicine that uses plants and their extracts for treatment and management of various diseased states. Nyctanthes arbour -tristis Linn. (Family Oleaceae), which has long been used traditionally for various medicinal purposes in the Indian sub continent. Each part of the plant has some important medicinal value and is thus commercially exploitable. It is now considered as a valuable source of several unique products for the medicines against various diseases and also for the development of some industrial products. The present study is to focus on the potential phyto-chemicals and pharmacological activity of plant N. arbor -tristis. In view of this, the study was designed to investigate for chemical constituents, anti-cancer and anti-inflammatory activities of solvent leaf extracts. Phytochemical screening revealed the presence of alkaloid, steroids etc. The extract exhibited significant anti-cancer and antiinflammatory properties and the observed biological activities in this study provide scientific validation of ethnomedicinal use of this plant.
