Determination of phenolic compounds in prunus domestica leaves extract

Abstract

Qualitative composition and content of phenolic compounds in the dry extract obtained from plum leaves have been studied. Seven phenolic substances were found, including three hydroxycinnamic acids and four flavonoids. The dominant substances were chlorogenic acid (2436.89 mg/100g) and rutin (926.32 mg/100g). Free monosaccharides, such as glucose and rhamnose, were identified in the extract, and their amount was determined by HPLC. The obtained results showed the prospects of creating a new drug with antioxidant activity on the basis of the plum leaves dry extract.

Cosmetic potentials of Prunus domestica L. leaves

“…In 2015, studies were also carried out on P. domestica leaves, but the authors did not specify the varieties used . The compounds they identified by HPLC are the same as those found in the varieties of our study, i.e.…”

“…Flavonoids such as domesticoside, prudomestin and isorhamnetin have been isolated from bark, heartwood and flowers respectively . Phenolic compounds such as quercetin, isoquercetin, kaempferol, chorogenic acid, quinic acid and caffeic acid are also present in plum leaves, but these are not much exploited …”

“…To date, only a few publications have focused on the characterization of P. domestica leaves. Their chemical composition, rich in phenolic compounds, was correlated with antioxidant and anti‐aging activities as well as photoprotective benefits …”

“…14,17 Phenolic compounds such as quercetin, isoquercetin, kaempferol, chorogenic acid, quinic acid and caffeic acid are also present in plum leaves, but these are not much exploited. 18 Furthermore, the agro-food industry produces about 800 000 tons of waste per year. 19 The by-products plum seed and plum pomace have been studied for possible valorization in biofuel and as dietary food respectively.…”

“…Their chemical composition, rich in phenolic compounds, was correlated with antioxidant and anti-aging activities as well as photoprotective benefits. 18,27 The aim of this study was to evaluate the biological potential of P. domestica leaves, especially their ability to inhibit elastase, hyaluronidase, tyrosinase and lipoxygenase, as well as their antioxidant properties. Characterization of active molecules was performed by high-performance liquid chromatography coupled with mass spectrometry using an electrospray ionization source (HPLC/ESI-MS).…”
