Azucena is an evergreen, with a stout and tuberous rootstock. Basal leaves are linear, 40 to 60 centimeters long, less than
1 centimeter wide, those on the stem much shorter. The inflorescence is erect,
0.5 to 1 meter high. Flowers are fragrant, waxy white, in pairs, 5 to 6
centimeters long, and the segments, oblong-lanceolate, 1 to 1.5 centimeters long.
Cultivated for its
- Volatile oil from
the flowers isolated tuberone.
- Methyl anthranilate has been noted in the tuberose oil.
- Inulin has been reported in the bulbs,
- Leaves yielded a 9,11 dehydrohecogenin 3-O glucose xylose galactoside, Kaemferol 3-O, α-D glucoside, Plianthoside B and C.
- Diuretic, emetic, maturative.
• Bulbs have been
used in decoction for gonorrhea.
• Poultice of bulbs employed as maturative in the formation of
pus in boils or abscesses.
• In India, flowers used as diuretic
• In Sind, bulbs are dried, powdered
and used for gonorrhea.
• Perfumery: Volatile oil used in perfumery.
• Aromatherapy: In aromatherapy, the warm and seductive scent is useful as a hypnotic for women suffering from insomnia and depressed with low sexual drive.
• Steroidal Glycosides / Cytotoxic Activity: Study of aerial parts of Polianthes tuberosa isolated a new bisdesmosidic cholestane glycoside and 3 new spirostanol saponins along with known cholestane glycoside. The compounds were evaluated for cytotoxic activity on HL-60 human promyelocytic leukemia cells.
• Immunosuppressive Activity: Study yielded an acidic polysaccharide (ANK-102) from P tuberosa cells. Pretreatment with ANK-102 deteriorated the murine survival against lethal injection of Listeria monocytogenes, eliminated mainly by macrophages through T-cell mediated immune response.
• Spirostanol and Furostanol Glycosides / Cytotoxicity: Study yielded six new steroid glycosides - two spirostanols, polianthosides B and C, and four furostanols, polianthosides D-G - from the fresh tubers of PT, together with seven known spirostanols and a known furostanol saponins. The cytotoxic activities against HeLa cells are reported.
• Mosquito Larvicide: Study evaluated the larvicide and biting deterrence activity of buds of Polianthes tuberosa against Culex quinquefasciatus and Anopheles stephensi. Both crude and methanol extract showed efficient activity against Cx. quinquefasciatus suggesting use as a mosquito larvicide agent.
• Antibacterial: The methanol extracts of the flower of Qiusqualis indica, Calothrophis gigantea and Polianthes tuberose showed significant antibacterial activity against microbes K. pneumonia, P. aeruginosa, P. mirabiilis, E. coli, MRSA and B. subtilis. Flower extracts of both dry and wet flowers of P. tuberose showed impact only on Proteus mirabilis and E coli at higher concentrations only.
