Spectrophotometric Studies of Indolic Compounds from <i>Vinca Minor</i> L.

Abstract The most medically representative plant in the Apocynaceae family is Vinca minor . a perennial, herbaceous plant, commonly known as Saschiu. In present research we aimed to isolate indole compounds from L. and carry out some physico-chemical studies on these compounds: UV-VIS spectroscopy determination of polyphenols content using Folin-Ciocâlteu method. spectrophotometric study alcoholic extracts obtained leaf stem was performed method VWR UV-630PC double beam spectrophotometer. Both samples had specific absorption maxima detected range 225-350 nm absorbance maximum both cases 3.5 (u.a- absorbency units). total determined by different concentrations: 40%, 70%, 96% (T40, T70, T96, F40, F70, F96) spectrophotometer model JASCO- 550 UV VIS. Regarding L., concentrations were between 812.50 mg / 100g pv 1737.50 case strain, results 1525.00-3962.50 GAE 100 g pv, that accordance with literature.
