The Short Answer
Loquat seed extract contains triterpenes like ursolic acid and oleanolic acid that inhibit NF-κB and p38 MAPK inflammatory pathways while enhancing antioxidant enzymes. Clinical studies demonstrate significant reductions in cholesterol, triglycerides, and blood glucose at 40-400 mg/kg daily dosing.

Health Benefits
Supports respiratory health by acting as an expectorant and reducing bronchial inflammation.
Enhances immune resilience through triterpenes and polyphenols that modulate immune responses.
Provides potent antioxidant protection by neutralizing free radicals and reducing oxidative stress.
Optimizes metabolic health by promoting liver detoxification and improving insulin sensitivity.
Supports skin health by reducing inflammation and promoting collagen synthesis
Offers neuroprotection by combating oxidative damage in neural tissues
Promotes digestive wellness by soothing inflammation and supporting gut microbiota.
Origin & History
Loquat Seed Extract is sourced from the seeds of Eriobotrya japonica, a tree native to Southeast China and widely cultivated across Asia, the Mediterranean, and parts of the U.S. Revered in traditional Chinese medicine, this botanical concentrate is known for its potent antioxidant, antimicrobial, and anti-inflammatory properties, supporting respiratory, digestive, metabolic, and dermatological health.
“In traditional Chinese medicine, Loquat seed has been prized for generations as a soothing respiratory and digestive remedy, celebrated for clearing heat, moisturizing lungs, and detoxifying the liver. Now gaining recognition in modern herbal therapeutics and skincare, it bridges ancient botanical wisdom and science-backed wellness.”Traditional Medicine
Scientific Research
Scientific research affirms Loquat Seed Extract’s bioactive profile, highlighting its antioxidant, anti-inflammatory, hepatoprotective, and antimicrobial actions. Studies support its potential in immune modulation, skin health, and metabolic balance, with ongoing research exploring its broader therapeutic applications.
Preparation & Dosage
Common Forms
Standardized extract (powder, capsules), tinctures.
Traditional Use
While the fruit and leaves were traditionally used in Chinese and Japanese medicine for respiratory and digestive ailments, the seed extract is a modern concentration.
Modern Use
Incorporated into respiratory supplements, blood sugar-regulating formulations, antioxidant-rich teas, and dermatological products.
Dosage
400–800 mg standardized extract daily
Nutritional Profile
- Phytochemicals: Triterpenes (ursolic acid, corosolic acid), Polyphenols, Flavonoids (quercetin, kaempferol), Saponins
- Bioactives: Amygdalin (Vitamin B17), Polysaccharides
- Minerals: Potassium, Calcium, Magnesium
How It Works
Mechanism of Action
Triterpenes including ursolic acid and oleanolic acid inhibit pro-inflammatory cytokines TNF-α, IL-6, and IL-8 by suppressing NF-κB, p38 MAPK, and ERK signaling pathways. The extract upregulates antioxidant enzymes superoxide dismutase, catalase, and glutathione peroxidase while modulating Nrf2 and CYP2E1 expression. Pentacyclic triterpenes induce apoptosis in cancer cells and suppress Th17 cell differentiation for immune modulation.
Clinical Evidence
Animal studies using 40-400 mg/kg daily for 6 weeks showed significant decreases in total cholesterol, LDL, and triglycerides with onset at 2-3 weeks. In vitro studies demonstrate >66.7% antioxidant inhibition at 1000 ppm, nearly matching pharmaceutical-grade TBHQ. Liver enzyme suppression (GOT, ALP, GGT) and body weight reduction were observed in high-fat diet animal models. Human clinical trial data remains limited, with most evidence derived from animal and cell culture studies.
Safety & Interactions
No specific safety data, adverse events, or contraindications are documented in current research literature. Potential interactions with cytochrome P450 enzymes (particularly CYP2E1) suggest caution with medications metabolized through these pathways. No pregnancy, lactation, or pediatric safety data is available. Healthcare provider consultation is essential before use, especially for patients on pharmaceutical medications or with chronic health conditions.

Frequently Asked Questions
What is the effective dosage of loquat seed extract?
Animal studies demonstrate efficacy at 40-400 mg extract per kg body weight daily for 6 weeks. Human equivalent dosing has not been established in clinical trials.
Which part of the loquat plant is most effective?
Research indicates fruit extract shows the highest potency for cholesterol and LDL reduction compared to leaf and seed extracts. Leaf extract demonstrates superior anti-inflammatory and neuroprotective effects.
How long does loquat seed extract take to work?
Animal studies show metabolic benefits including cholesterol and glucose reduction begin at 2-3 weeks of daily administration. Antioxidant effects may occur more rapidly based on enzyme activity studies.
Can loquat seed extract interact with medications?
The extract modulates CYP2E1 enzyme expression, potentially affecting medications metabolized by cytochrome P450 pathways. No specific drug interactions have been documented in clinical studies.
Is loquat seed extract safe during pregnancy?
No safety data exists for pregnancy, lactation, or pediatric use. The lack of human clinical trials makes safety assessment impossible for these populations.
