In vitro lipolytic, antioxidant and anti-inflammatory activities of roasted pistachio kernel and skin constituents.

A comprehensive phytochemical analysis was conducted on pistachios to identify the differential contributions of skin and kernel phytochemicals to in vitro bioactivity. Qualitative and quantitative analyses of skin and kernel non-polar extracts (SNP and KNP, respectively) indicated that the major components are fatty acids (696.36 and 879.

Chemical composition, antioxidant and anti-inflammatory properties of pistachio hull extracts.

Phytochemical and bioactivity analyses of pistachio hulls revealed the presence of anacardic acids (3198mg/100g), fatty acids (1500mg/100g), and phytosterols (192mg/100g) as major components. Carotenoids (4.93mg/100g), chlorophylls (10.

Characterization of Phenolic Compounds and Antioxidant and Anti-inflammatory Activities from Mamuyo (Styrax ramirezii Greenm.) Fruit.

Extracts of Styrax ramirezii Greenm., a fruit traditionally valued for health and wellness in Mexico, were analyzed phytochemically and evaluated for antioxidant and anti-inflammatory activity. Six norneolignans were identified by HPLC-TOF-MS, and the two major compounds were isolated for further evaluation.

Phenylphenalenones and oxabenzochrysenones from the Australian plant Haemodorum simulans.

Chemical investigation of the Australian plant Haemodorum simulans (Haemodoraceae) resulted in the isolation of two new phenylphenalenones, haemoxiphidone and haemodordioxolane from the bulbs together with the first report of an oxabenzochrysenone glycoside, haemodoroxychrysenose from the aerial parts of the plant. Also isolated were two previously described phenylphenalenones 5,6-dimethoxy-7-phenyl-1H,3H-naphtho[1,8-cd]pyran-1,3-dione and haemodorone and two oxabenzochrysenones 5-hydroxyl-2-methoxy-1H-naphtho[2,1,8-mna]xanthen-1-one and 5-methoxy-1H-naphtho[2,1,8-mna]xanthen-1-one. The X-ray structure of the phenylphenalenone 5,6-dimethoxy-7-phenyl-1H,3H-naphtho[1,8-cd]pyran-1,3-dione was secured for the first time.

Application of HPLC-NMR in the identification of plocamenone and isoplocamenone from the marine red alga Plocamium angustum.

A combination of on-line HPLC-NMR and off-line chemical investigations has resulted in the identification of the previously reported polyhalogenated monoterpene plocamenone, together with the new structural analogue isoplocamenone from the crude extract of the marine alga Plocamium angustum. On-flow and stop-flow HPLC-NMR analyses (including the acquisition of WET 2D NMR spectra) rapidly assisted in the identification of the major component plocamenone and in the partial identification of its unstable double bond isomer isoplocamenone. Conventional off-line isolation and structural characterization techniques were employed to unequivocally confirm both structures, leading to a structural revision for plocamenone, as well as to obtain sufficient quantities for biological testing.
