چکیده

The paper presents the results of the qualitative and quantitative determination of scopoletin (SLT) in Physalis alkekengi and Solanum dulcamara (Solanaceae) by highperformance liquid chromatography tandem mass spectrometry (HPLC/MS). The plant samples were harvested around Iasi on July 2007, July 2008, August-September 2009. Scopoletin was extracted from dried leaves by two methods: with methanol 70% by reflux and with ethanol 70%. Hydrolyzed samples showed significant levels of scopoletin: for Physalis alkekengy the values were between 83.32 and 267.90 mg/ 100 g product and for Solanum dulcamara: 123.13 and 438.93 mg/ 100 g product. The mean values are lower for Physalis alkekengi compared with those for Solanum dulcamara. Rezumat Lucrarea prezintă rezultatele analizei calitative şi cantitative a scopoletinei din Physalis alkekengi şi Solanum dulcamara, familia Solanaceae. Determinările s-au efectuat printr-o metodă modernă de cromatografie de înaltă performanţă cuplată cu spectrometrie de masă. Probele au fost recoltate din regiuni din jurul municipiului Iaşi în trei perioade (iulie 2007, iulie 2008, august-septembrie 2009). Scopoletina s-a izolat din frunzele uscate prin două metode: refluxare cu metanol 70% şi extracţie alcoolică, cu alcool etilic 70%. În probele hidrolizate s-au găsit concentraţii semnificative de scopoletină. Pentru Physalis alkekengy valorile au variat între 83,32 şi 267,90 mg/ 100 g produs, iar pentru Solanum dulcamara între 123,13 şi 438,93 mg/ 100 g produs. Valorile medii de scopoletină pentru Physalis alkekengi sunt mai mici comparativ cu cele pentru Solanum dulcamara.

Hplc/ms Analysis of Solanine in Physalis Alkekengi and Solanum Dulcamara

We developed a HPLC/MS method for the identification and determination of solanine in plants. This method was applied for samples of Solanum dulcamara (from Iaşi and Vânători Neamţ areas in Romania) and Physalis alkekengi (from Bucium and Breazu, Iaşi, Romania) during August-September 2009. Isolation of solanine was performed by extraction with a mixture consisting of water/methanol/acetic acid...
