Constituents of Helichrysum stoechas variety olonnense

Exploring the antioxidant potential of Helichrysum stoechas (L.) Moench phenolic compounds for cosmetic applications: Chemical characterization, microencapsulation and incorporation into a moisturizer

“…There are some similarities in the phenolic profile identified in H. stoechas flowers from Portugal and samples from Italy (Carini et al, 2001) and France (Lavault and Richomme, 2004). A sample from Turkey (Albayrak et al, 2010) the phenolic acids profile was similar to the Portuguese sample, whereas for flavonoids some differences were found.…”

“…Although antioxidant properties of H. stoechas methanol extract (Carini et al, 2001;Albayrak et al, 2010;Barros et al, 2010) and phenolic compounds (Lavault and Richomme, 2004) have been already investigated, there are no reports neither on the hydroalcoholic extract nor on its most used form, decoction. Moreover, to the best of our knowledge, microencapsulation of such extracts has never been studied.…”

“…Those authors identified flavones, such as apigenin and naringenin derivatives. Lavault and Richomme (2004) and Carini et al (2001) did not 15 present quantification data on these compounds. Albayrak et al (2010) were the only authors that presented quantification data, in which the major component present was chlorogenic acid, followed by apigenin 7-glucoside.…”

Bioassay-guided isolation of anti-inflammatory and antinociceptive principles from a folk remedy, Rhododendron ponticum L. leaves

“…Effects of the compounds against TPA-induced ear edema in mice as measurement swelling thickness and weight measurement of edema 1 was a mixture of two quercetin glycosides, hyperoside, a 3-O-galactoside, (major constituent, 2/3 of the mixture) and isoquercitrin, a 3-O-glucoside, (minor constituent, 1/3 of the mixture) by comparison of the spectral data with those reported in the previous studies (Lee et al, 2003;Lavault and Richomme, 2004). Compound 2 was identified as quercitrin, a 3-O-rhamnosylquercetin, by comparison of its 1 H NMR spectral data with those found in the literature (Pyo et al, 2002).…”

Antinociceptive effect from Ipomoea cairica extract

“…The quinic acid esters were identified by their 1 H and 13 C NMR and UV data (Um et al, 2002;Lavault and Richomme, 2004). KCl was identified by X-ray diffraction analysis.…”
