Miris

The aroma of the extracts is floral, fruity, sweet, fig-like, leathery and slightly herbaceous. A blue lotus absolute is described as a sweet, fruity and powdery floral with facets of stone fruit and lilacs. Nymphaea caerulea is described as incorporating mild, honeyed undertones. The same absolute is also described as watery but extremely complex, an aquatic floral.

Detaljno

Botany

Nymphaea caerulea Savigny belongs to the family Nymphaeaceae and is known as blue lotus, water lily and Egyptian lotus. It is an aquatic perennial plant that grows worldwide along rivers and lakes, from sea level to 2700 m. Its floating leaves are round or oval and flat, up to 40 cm in diameter, and arise from a perennial spongy rhizome submerged in the mud. The leaves stay afloat because their top surface is covered with a smooth, waxy cuticle and the margins are slightly rolled up. In the wild it is found throughout most of the eastern half of Africa and in parts of southern Arabia. The name Nymphaea caerulea is a recognized synonym of Nymphaea nouchali var. caerulea. The water lily family contains five genera with about 70 known species.

Composition of the extracts

The volatile fraction makes up 38.7 to 65.1% of the total extract. The three main constituents of the absolute are 6,9-heptadecadiene (11.05 ± 1.53%), benzyl alcohol (10.46 ± 1.42%) and tetradecanol (5.32 ± 0.74%). In the concrete the three main constituents are 6,9-heptadecadiene (11.95 ± 1.65%), n-tricosane (8.03 ± 0.18%) and benzyl alcohol (7.58 ± 0.85%). The vapor phase of a live N. caerulea flower contained mainly 6,9-heptadecadiene (40.1%), pentadecane (15.5%), 8-heptadecene (15.3%) and benzyl acetate (10.4%). A comparison of stamens, pistils and petals reported that the stamens produce the majority of the volatiles.

Alkaloids and safety

The plant contains the psychoactive alkaloids nuciferine and apomorphine. In the authentic extracts, apomorphine and nuciferine were virtually absent. Blue lotus concretes and absolutes were free of apomorphine and held negligible traces of nuciferine (10-72 ppb). For authentic concrete or absolute diluted as a fragrance ingredient, the available information does not indicate major safety concerns for topical application.

Commercial products

Eleven commercial blue lotus products bought online varied greatly in aroma, and none resembled the original aroma. All of the tested samples contained synthetic fragrance components.

Zanimljivosti

Petals of the blue water lily were found in King Tutankhamun's tomb in 1922. At Heliopolis, the origin of the world was taught to have been when the sun god Ra emerged from a lotus flower growing in primordial waters. The flower played a role in the Hathoric Festival of Drunkenness, in which ancient people got drunk, passed out and reportedly saw the face of Hathor, goddess of love, beauty and fertility, when they awoke.

Dobijanje i hemija

Način dobijanja

Authentic blue lotus extracts were made in industrial settings, with average yields of 0.18% for the concrete and 0.09% for the absolute. Fresh flowers are shredded and extracted twice with hexane (1:2, w/v) in an enamel tank with continuous stirring for 12 h. The hexane is drained and filtered, and the extracts are left to settle for 4 h and filtered again. The solvent is recovered and the extract concentrated under atmospheric pressure until all of the hexane has evaporated. The concentrated extract is called concrete. To prepare the absolute, the concrete is dewaxed with 95% ethanol (1:5, w/v), stirred carefully and placed in a freezer for more than 12 h. The extract is filtered, and the filtrate is concentrated under low pressure until all of the solvent has evaporated.

Water lily notes are placed as a middle note, bridging bright citrus openings with deeper floral, musky or woody bases. The note pairs well with bergamot, pear and neroli, and in floral compositions it enhances peony, freesia and jasmine without adding density. A blue lotus absolute from Nymphaea caerulea is also described as a middle note.
