Synthesis of Chlorogenic Acids and Chlorogenic Acid Lactones

open access: yes, 2011
The chlorogenic acids are a family of esters formed between certain trans-cinnamic acids and quinic acid. Chlorogenic acids are among the most abundant polyphenols, which are naturally occurring in plants, with various biological activities beneficial to

Integrated phytochemical and bioactivity profiling of Xanthium strumarium fruits from Korea and China: Implications for origin‐specific quality specification

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Geographic origin influences the phytochemical composition and biological activities of medicinal plant resources. Xanthium strumarium L. (XS) fruit is widely used in East Asian traditional medicine. However, current pharmacopeial standards primarily recognize Chinese‐derived material, despite the availability and traditional use of

Testing optimal defense theory: Root resistance selection in chicory (Cichorium intybus) reduces foliar defense and alters aphid performance and feeding behavior

open access: yesPest Management Science, EarlyView.
Root‐focused resistance in chicory reduces defenses in leaves, impairing root aphids but enhancing foliar aphid performance. Selecting root resistance can create unintended trade‐offs across plant organs. Abstract BACKGROUND Plants are constantly exposed to a wide range of herbivores at both aboveground (AG) and belowground (BG) levels, involving ...

Harnessing Natural Compounds in Psoriasis: Targeting Cellular Pathways for Effective Therapy

open access: yesPhytotherapy Research, EarlyView.
Natural compounds act on key cellular pathways in psoriasis by suppressing keratinocyte hyperproliferation, modulating Th17/IL‐17‐mediated immune responses, and reducing oxidative stress. These multi‐target effects highlight their potential as safer adjunctive therapies alongside conventional treatments.

Ashwagandha: Is It Safe? Part 2: A Preclinical Evidence Review

open access: yesPhytotherapy Research, EarlyView.
ABSTRACT The preclinical evidence for the safety of ashwagandha (Withania somnifera (L.) Dunal, AS) is reviewed, and its preparations (extracts) and constituents, from the general toxicity in animal models to in vitro and cell culture studies, which may elucidate mechanisms of action and explain clinical case reports.
