Aeollanthus suaveolens Mart. ex Spreng. - syn.Aeollanthus suavis Mart.; Aeollanthus cassawa Taylor; Aeollanthus heliotropioides Oliv.; Aeollanthus glabrifolius De Wild. - Lamiaceae
catinga de mulata (brazil.), cegadinka (brazil.); macassa (brazil.); bwalangino (Nigeria); otek (Cameroon)

Succulent annual herb up to 0.5m tall, native to southern tropical Africa, cultivated in Brazil; stems glabrous to hispidulous; leaves sessile or shortly petiolate; blade lanceolate to elliptic or ovate-lanceolate; flowers secund, single, closely placed, subsessile; corolla blue to purple, 4-5mm long; nutlets ovoid or oblong, smooth. JSTOR

„Cultivated as medicinal plant against skin, ear and eye diseases in Brazil. Used as an important voodoo plant for ritual baths by the Afro-Brazilians. Grown in northern Nigeria for its very aromatic foliage, which is used to flavour soup. Employed as a medicinal plant and soap-substitute in tropical Africa. The essential oil of the plant is of potential value in perfumery. Wild distribution: Tropical Africa (Nigeria to southern Sudan and Kenya in the north to South Africa); naturalized in South America (Brazil).“

The essential oil from flowering material is dominated by linalool (41.8%), linalyl acetate (15.8%) and (E)-β-farnesene (14.0%). Oil from vegetative material contained linalool (35.5%), linalyl acetate (12.4%) and (E)-β-farnesene (17.0%). The distinct coconut-like scent is provided by δ-decalactone (traces-0.01%) and massoia lactone (0.7%) in flowering material; oil from vegetative material contained δ-decalactone (0.4%) and massoia lactone (7.0%).

„Water-distilled essential oils of Aeollanthus suaveolens were analyzed by both GC and GC/MS. The major components identified in the oil of the dried plant (sample A) were (E)-β-farnesene (32.8%), linalool (31.6%), 2-decen-5-olide (massoialactone; 15.0%) and linalyl acetate (8.5%). The main constituents found in the oil of the fresh plant (sample B) were linalool (49.3%) and (E)-β-farnesene (34.9%). The compounds 2-decen-5-olide and linalyl acetate were detected only in minute quantities in the fresh plant.“

„The volatiles found in the headspace of Aeollanthus suaveolens were analyzed by solid phase microextraction coupled with GC/MS. This led to the identification of the 23 compounds. During steam distillation of the oil of A. Suaveolens, the very fragrant lactones, massoia lactone and δ-decalactone, were concentrated in the residue from which they can easily be extracted for perfumery purposes.“

„The essential oils from leaves (sample A) and flowers (sample B) of Aeolanthus suaveolens Mart. ex Spreng were obtained by hydrodistillation and analyzed by GC, GC-MS, and chiral phase gas chromatography (CPGC). Six compounds have been identified from the essential oils, representing ca 94.3 and 93% of the oils corresponding to samples A and B, respectively. The major constituents of samples A and B essential oils were respectively, linalool (34.2%/34.9%), (-)-massoialactone (25.9%/17.0%) and (E)-β-farnesene (25.4%/29.1%). The enantiomeric distribution of the monoterpene linalool was established by analysis on heptakis-(6-O-methyl-2,3-di-O-pentyl)-β-cyclodextrin capillary column.“
