• Recent NIPH Clinical Trials: Safety analysis of luteolin for prostate cancer
• Indications: This product has antitussive, expectorant effect. The antitussive effect is through suppressing the cough center; the expectorant effect of this product is related to its ability of promoting the secretion of the respiratory tract gland and dissolving the acidic mucopolysaccharides in the sputum. It also has anti-inflammatory, anti-allergic and immune enhancement effect. It also has inhibitory effect on Staphylococcus aureus, Streptococcus pneumoniae and Pseudomonas aeruginosa. It can also be used for the treatment of chronic bronchitis and other respiratory diseases sputum. Luteolin compound prescription is mainly used for relieving cough, eliminating phlegm, diminishing inflammation, treating cardiovascular diseases, and treating amyotrophic lateral sclerosis, severe acute respiratory syndrome (SARS), hepatitis, etc.
• Description: Luteolin is a polyphenolic flavone found in many plants including soybeans and perilla leaves. Luteolin is one of the most potent flavanoid inhibitors of soybean and reticulocyte 15-lipoxygenases, with an IC50 of 0.6 μM. Luteolin has also been found to inhibit the release of TNFα from neutrophils, and to inhibit matrix metalloproteinases. Luteolin is a flavone derived from Honeysuckle(Lonicera japonica Thunb). Luteolin is widely distributed in nature. It can be isolated from a variety of natural herbs, vegetables, and fruits. At present, luteolin is found mainly in honeysuckle, chrysanthemum, Schizonepeta, Ajuga, artichokes, Scutellaria, and Callicarpa nudiflora natural herbs. Dietary sources include celery, broccoli, green pepper, parsley, thyme, dandelion, perilla, chamomile tea, carrots, olive oil, peppermint, rosemary, navel oranges, and oregano. It can also be found in the seeds of the palm Aiphanes aculeata.

• Uses: Luteolin has been used:to induce and elucidate the apoptotic pathway in renal cell carcinoma 786-O cellsas an additive in M9 minimal medium to induce nodF gene expressionas a reference standard to qualitatively and quantitatively analyse luteolin using reverse phase-high performance liquid chromatography with diode array detector (RP-HPLC-DAD)as a reaction supplement for β-galactosidase assayto elucidate the anti-inflammatory efficacy of luteolin in pseudorabies virus infected RAW264.7 cell line by measuring the anti-inflammatory mediators production and also cell viability and cytotoxicity assay Hydroxylated flavone derivative with strong anti-oxidant and radical scavenging properties. Suggested to play a role in cancer prevention
• Clinical Use: The natural extract containing luteolin has been used in clinical treatment of many diseases. Lamiophlomis rotata Kudo capsule is made from traditional Chinese medicine Lamiophlomis rotata Kudo, which consists of the medicinal components such as flavonoids, saponins, sterols, amino acids, and many trace elements. Among these components, luteolin content is not less than 0.80 mg/g. This capsule is mainly used for a variety of surgical incision pain, postoperative bleeding, fracture, sprain of muscles, rheumatic pain, dysmenorrhea, uterine bleeding, gingival swelling, and bleeding.
