Leaves of Lycium barbarum are widely used as medicine vegetables and functional tea in China. The main flavonoids present in the leaves were separated and identified by high performance liquid chromatography (HPLC), liquid chromatography-atmospheric pressure chemical ionization mass spectrometry (LC-(APCI) MS) and ultraviolet-visible spectra with shift additives. The predominant flavonoid was identified as rutin. Leaves are the rutin-rich parts (16.03–16.33 mg/g). In the wild and cultivated L…

Comparative studies on antioxidant activity and polyphenolic content of Lycium barbarum L. and Lycium chinense Mill. leaves.
TLDR
In the antioxidant assays, both extracts exhibited important antioxidant activities, as witnessed by the three methods, both correlated with their total polyphenolic content.
Chromatographic Determination of Phenolic Acids and Flavonoids in Lycium barbarum L. and Evaluation of Antioxidant Activity
Polyphenols are the important active compounds present in the fruits of Lycium barbarum L. The objectives of this study were to develop an ultra-high performance liquid chromatography with UV…
Polyphenolic Content, Antioxidant and Antimicrobial Activities of Lycium barbarum L. and Lycium chinense Mill. Leaves
TLDR
The results suggest that L. chinense extract was more active than L. barbarum against both Gram-positive and Gram-negative bacterial strains and these species are valuable sources of flavonoids with relevant antioxidant and antimicrobial activities.
Selenium increases chlorogenic acid, chlorophyll and carotenoids of Lycium chinense leaves.
TLDR
Rutin, quercetin, kaempferol and apigenin-7-O-(6'-O-acetyl) glucose-rhamnose proved to be not significantly influenced by selenium, hence increasing the medicinal value of L. chinense leaves.
Potential of galled leaves of Goji (Lycium chinense) as functional food
TLDR
In infected Goji leaves, the polyphenol content was significantly increased and the level of chlorogenic acid was increased by 36% in galled leaves, and the content of rutin in galling leaves was also elevated.
Biologically Active Compounds from Goji (Lycium Barbarum L.) Leaves Aqueous Extracts: Purification and Concentration by Membrane Processes
TLDR
Evaluating the potential of a sustainable process for the recovery of phenolic compounds from Goji leaves through a combination of aqueous extraction and membrane-based operations found a 1 kDa membrane exhibited the best performance in terms of purification of polyphenols from the clarified aqueously extract.
Phenolic Constituents of the Chilean Herbal Tea Fabiana imbricata R. et P.
TLDR
The health-promoting properties reported for this herbal tea can be associated with the presence of several phenolics with known antioxidant, diuretic and antiinflammatory activity.
