Phlomoides tuberosa

Phlomoides tuberosa (syn. Phlomis tuberosa) is a perennial flowering plant in the family Lamiaceae native to China, Kazakhstan, Kyrgyzstan, Mongolia, Russia; SW Asia and Europe. Enlarged, tuberous roots give rise to erect stems to 150 cm bearing purple-red flowers.[2]

Chemistry

Phytochemical analyses of Phlomoides tuberosa leaves have found flavonoids apigenin, apigenin-7-O-glucuronide, luteolin, luteolin-7-O-glucoside, luteolin-7-О-glucuronide, orientin, isoorientin,[3][4][5][6] phenylpropanoids acteoside (verbascoside), forsythoside B,[7] decaffeoyl-acteoside, leucosceptoside A, marthynoside, neolignanes,[8] iridoids sesamoside, 5-desoxy-sesamoside, shanzhiside methyl ester, lamalbide,[9] 8-O-acetyl-shanzhiside, phloyoside I, chlorotuberoside,[8] sterols, triterpenes oleanolic acid, ursolic acid.[10] Dried leaves of plants collected in Buryatia yielded 0.02% of essential oil with a weak aroma with dominant phytol, linalool, eugenol and caryophyllene oxide.[11] The seed has yielded 11.8% of oil, including 3.3% gadoleic acid and some fatty acids containing the unusual allene group, 25.1% laballenic acid and 2.9% phlomic acid.[12] The roots shown the presence of oligosaccharides raffinose, stachyose, verbascose, flavonoids luteolin, linarin, quercitrin, phenylpropanoids acteoside, isoacteoside (isoverbascoside), forsythoside B, chlorogenic acid, decaffeoyl-acteosyde, iridoids shazhiside methyl ester, 8-O-acetyl-shanzhiside methyl ester, 8-O-acetyl-shanzhigenin methyl ester, floyoside I, phlotuberosides I and II, phlorigidoside C, diterpenes (abietanes, labdanes).[13][14]

Uses

The Kalmyks are said to have eaten the cooked root, calling the plant bodmon sok.[15] Another source for Mongolia has the plant used as a folk restorative medicine against intoxication, tuberculosis, pulmonary and cardiovascular diseases and rheumatoid arthritis.[13] Buryat lamas used some part of the plant to treat diarrhoea, eye and lung disease and as a sedative.[11]

The cultivar 'Amazone' has won the Royal Horticultural Society's Award of Garden Merit. [16]
