Luteolin is a natural flavonoid, belonging to the flavone class of polyphenol compounds. It is widely distributed in various plants, including fruits, vegetables, and medicinal herbs. Some common dietary sources of luteolin include celery, parsley, thyme, peppers, and chamomile tea.
Luteolin
This compound has attracted attention due to its potential health benefits and antioxidant properties. Luteolin has been studied for its anti-inflammatory, anti-cancer, and neuroprotective effects. It is believed to exert these effects through various mechanisms, including the modulation of signaling pathways and the inhibition of inflammatory mediators.
Research suggests that luteolin may help reduce inflammation by inhibiting the activity of pro-inflammatory enzymes and cytokines. Additionally, it has been investigated for its potential to inhibit the growth of cancer cells and induce apoptosis (programmed cell death) in certain types of cancers.
Moreover, luteolin has been studied in the context of neuroprotection, with some evidence suggesting its ability to protect against neurodegenerative disorders. It is believed to exert its neuroprotective effects by reducing oxidative stress, inflammation, and apoptotic processes in the brain.

Case. Exploring the Pharmacological Potential and Flavonoid Composition of Passiflora loefgrenii
Background
Passiflora loefgrenii, a relatively understudied plant species, has been investigated for its pharmacological potential and flavonoid composition. While Passiflora species are known for their diverse bioactive compounds, the specific properties of P. loefgrenii remain largely unexplored.
Sample
Three different extracts were obtained from various parts of the P. loefgrenii plant: young leaves (YL), adult basal leaves (AL), and stems (ST). These samples were subjected to detailed analysis to uncover the flavonoid composition and potential pharmacological applications.
Technical Platform and Procedure
The study employed a combination of High-Performance Liquid Chromatography with Diode Array Detection (HPLC-DAD) and Electrospray Ionization Tandem Mass Spectrometry (ESI-MS/MS) techniques. The antioxidant activity of the samples was assessed using the 2,2'-di-phenyl-1-picrylhydrazyl (DPPH) quenching assay. The evaluation included the determination of IC50 values and the generation of dose–response curves.
Results
1. Flavonoid Composition:
2. Antioxidant Activity:
3. Comparison with Other Passiflora Species:
4. Pharmacological and Therapeutic Implications:
HPLC-DAD (350 nm) chromatograms of flavonoids from P. loefgrenii young upper leaves (YL), basal adult leaves (AL) and stems (ST).
Comparison between HPLC-DAD (350) chromatograms of flavonoids from P. loefgrenii (A) and Passiflorae herba (B).
