People worldwide drink more than one million cups of chamomile tea daily. This ancient herbs popularity makes sense given its high apigenin content.
The latest scientific research reveals fascinating details about how much apigenin in chamomile tea. We’ll talk about the exact measurements and how this compound affects your sleep quality. This knowledge helps to decide how to add this beneficial compound to our daily routine.
What is apigenin? Understanding this powerful flavonoid
Apigenin is one of natures most intriguing compounds that belongs to the flavone subclass of flavonoids. This remarkable molecule forms the foundation for several naturally occurring glycosides and plays a vital role in plant biology and human health.
The body processes apigenin through a complex metabolic path. 5-10% of ingested apigenin gets absorbed in the small intestine. The remaining 90-95% moves to the colon and reaches millimolar concentrations.
Apigenin processing in the liver happens in two distinct phases. Phase one metabolism uses cytochrome P450 enzymes to create monohydroxy derivatives. Phase two metabolism follows with several processes:
- Glucuronidation and sulfation;
- Enteric and enterohepatic cycling;
- Conversion into luteolin;
- Formation of sulfated and glucuronidated conjugates.
Apigenin works through specific pathways to reduce inflammation. It activates different anti-inflammatory mechanisms, particularly p38/MAPK and PI3K/Akt pathways. The compound also stops IKB degradation, reduces COX-2 activity and prevents nuclear translocation of NF-κB.
Measuring apigenin content in chamomile tea
Scientists have made exciting discoveries about how much apigenin different types of chamomile tea contain. Their research gives us exact measurements and shows what affects this beneficial compound’s levels.
German vs. Roman chamomile: Which contains more apigenin?
German chamomile (Matricaria recutita) stands out as the clear winner when it comes to apigenin content. Lab tests confirm that German chamomile has 110 µg/mL of apigenin. This makes it the best choice if you want maximum benefits.
Roman chamomile has value too, but it contains less apigenin. It features compounds like chamamaeloside and other apigenin derivatives instead. That’s why German chamomile remains the top choice for medical uses.
Scientific studies that calculate apigenin in chamomile
Research shows detailed apigenin measurements:
- The ‘Bodegold’ chamomile cultivar produces about 0.704 mg apigenin per gram of dried tissue;
- Ray florets have higher concentrations, Egyptian varieties show 6.7% apigenin content compared to 2.3% in Lebanese varieties;
- Disk florets show different levels, Lebanese origin has 38.5% apigenin-7-O-glucoside while Egyptian varieties have 36.1%.
Factors that affect apigenin concentration in tea
Your chamomile teas apigenin levels depend on several things:
- Temperature plays a vital role in extraction efficiency. Research shows that apigenin extraction increases as temperature rises, reaching its best levels at 100°C. Keeping this temperature longer than 10 minutes doesn’t help much more.
- Storage conditions change how stable apigenin remains. Research shows that:
- Storage at room temperature leads to about 10% breakdown over 120 days;
- Keeping it in the fridge at 4°C shows similar breakdown patterns;
- Freezing at -20°C keeps apigenin content stable with no major breakdown.
- pH levels strongly affect apigenin stability:
- The best stability happens between pH 5-7;
- Breakdown increases at higher pH levels:
- 6% at pH 8;
- 9% at pH 9;
- 11-12% between pH 10-12;
- 48% at pH 13.
- Growing conditions like climate, seasons and harvest timing affect the final apigenin content.
The science behind apigenin’s sleep promoting effects
Scientists have shown great interest in understanding how apigenin helps promote sleep. New research reveals fascinating details about this natural compounds influence on our sleep patterns.
How apigenin interacts with GABA receptors
Sleep inducing properties of apigenin come from its interaction with gamma-aminobutyric acid (GABA) receptors in the brain. Lab studies show that apigenin binds to the benzodiazepine binding site of GABA type A receptors. This binding helps boost GABAs inhibitory effects and creates a calming effect on the central nervous system.
Research on apigenin and sleep quality
Research provides strong evidence that links apigenin to sleep regulation. A newer study, published in 2024 by Frontiers in Nutrition, showed a direct link between dietary apigenin intake and better sleep quality in adults.
The benefits of this compound go beyond just helping you sleep. Studies show that apigenin:
- Lowers stress hormone levels and increases serotonin in the hippocampus;
- Reduces monoamine oxidase activity and increases dopamine levels;
- Keeps BDNF levels high and maintains glial GDNF mRNA.
Comparing apigenin to pharmaceutical sleep aids
Apigenin works differently from regular sleep medications. Clinical trials that tested 270 mg of chamomile extract twice daily for 28 days showed better daytime functioning in patients with primary insomnia. A study also found that 220-1100 mg of chamomile extract taken over eight weeks helped reduce depression and anxiety symptoms, which led to better sleep.
Beyond sleep: other health benefits of chamomile tea
Chamomile is famous for helping people sleep, but this amazing herb contains over 120 chemical constituents that provide many health benefits. Here’s what science tells us about how chamomile tea can boost your wellness routine.
