Botany
Luyang-pula is a rhizomatous perennial, leafy herb forming large clumps, growing to 3-4 meters tall. Leaves are lanceolate, glabrous. Inflorescence is a terminal spike, often pendulous, showy, up to 90 centimeters long. Flowers are small, white, 1-2 , arising from the red bracts of the spike, to 2.5 centimeters long. Fruit is a capsule. Pseudostems formed by leaf sheaths emerge from underground rhizomes.

Luyang pula2

Constituents
Luyang pula4– Subextracts of leaves yielded a mixture of C28-C32 fatty alcohols, a 3-methoxyflavone and two steroid glycosides. The two latter metabolites were identified as kumatakenin, stiosteryl-3-O-6-palmitoyl-ß-D-glucoside and ß-sitosteryl galactoside.

Properties
– Studies suggest antioxidant, antimicrobial, antimycobacterial, anticancer properties.

Parts used
Bark, fruit, leaves and seeds.

Uses
Folkloric
– No reported folkloric medicinal use in the Philippines.
– In the West Indies, used for stomach complaints.

Study Findings
• Flavonoids: Study yielded flavonoids kaemferol-3-0-glucoronide and rutin. The butanolic extract contained the highest flavonoid percentage.
• Volatile Oils / Leaves and Flowers: The major components of leaf oil of A. purpurata were 1,8-cineole, ß-pinene and (E)-methyl cinnamate; the oil from the flowers was dominated by ß-pinene and a-pinene.
• Vasodilator Activity: Study showed A purpurata had a better vasodilator effect than control, results in agreement with the quantification of phenolic compounds in the extracts. It presents a possible natural source for bioactive compounds useful for the treatment of hypertension.
• Antimycobacterial: Study evaluated hexane and dichlormethane subextracts of leaves for antimycobacterial activity. In addition to anti-inflammatory activity, study also describes the phytochemical potential to treat tuberculosis.
• Antimicrobial: Study evaluated three solvent extracts of leaves, roots, and rhizomes for in vitro activity against six strains of bacteria and four pathogenic fungi. Ethanolic extract of rhizomes showed wide spectrum of activity against all tested bacteria, with notable activity only with Candida albicans.
• Anticancer / Antioxidant: Study evaluated an ethylacetate extract of AP for potential in-vitro antioxidant and anticancer activity. Results showed antioxidant and anticancer activity which may be due to the presence of alkaloids, flavonoids and terpenoids in the leaves.
• Antioxidant / Antioxidant: Study evaluated the enzymatic and non-enzymatic antioxidants of leaf extract of Alpinia purpurata. Results showed the potential to scavenge free radicals and protect against oxidative stress causing diseases.

Caution !
• Ginger supplements should be avoided by those with known allergy to ginger or other Zingiberaceae family members, including Alpinia purpurata.
• It has been suggested pregnant women should avoid ginger in the excessive amounts (more than 1 gram dry weight per day). The German Commission E recommends avoidance during pregnancy due to its possible inhibition of testosterone binding in the fetus. It should not be used for nausea of pregnancy and should be avoided by pregnant women with a history of bleeding disorders and miscarriages. (see:Luya)
• Ginger decreases platelet adhesiveness and should be used with caution by people on anticoagulant therapy.
