-"In the countries of Central and Western Europe, linden flowers are a traditional herbal remedy made into an herbal..., considered to be of value as an anti-inflammatory in a range of respiratory problems: colds, fever, flu, sore throat, bronchitis, and cough."

 "Thus the difference in the composition of the aroma compounds between the headspace and the **essential oil** is clearly shown. This is also the case with **dried lime tree flowers** (Flores Tiliae). The main constituents of the essential oil of this drug are 1,8-cineole, linalol, carvone, thymol and carvacrol (concentration more than 2 %), but all of these volatiles only be detected in the headspace in a concentration below. On the other hand p-cymene, fenchone, and  α- and β-thujone are only trace compounds of this essential oil.\\ "Thus the difference in the composition of the aroma compounds between the headspace and the **essential oil** is clearly shown.

 +Later on, headspace analysis of hyacinth flowers showed that 2,6-dimethylocta-1,3,5,7-tetraenes and 2,6-dimethylocta-3,5,7-triene-2-ols are associated with charcoal as adsorbing material. It was shown that these compounds are artefacts from ocimene which mainly arise during sampling with charcoal. \\

-"More than 45 headspace constituents of the **living lime tree flowers** were detected by gas chromatographic-spectroscopic methods; more than 35 of them were identified. Main components (concentration higher than 3%) of this mixture with an odour impression similar to that of the genuine lime tree flowers' as well as with weak fresh and aromatic side-notes were limonene (22%), p-cymene (22%), δ3-carene (15%), germacrene-D (9%), β-phellandrene (4%) and farnesol (4%). Using a GC-sniffing technique, regions of specific odour impressions were found by means of which the total odour of the headspace sample of the living flowers was determined: the aromatic odour was caused especially by p-cymene, trans-carveol and germacrene-D; the floral part by linalool, 2-phenylethanol, trans-rose oxide, geraniol, nerol, 2-phenylethyl acetate, geranyl acetate and partly, nerolidol; the fresh part by camphene, limonene and camphor; and the narcotic part by 2-phenylethanol, nerol, heliotropin and farnesol. However, indole, 2-phenylethyl benzoate, farnesyl acetate and some other sesquiterpenes had additional odour notes. The headspace sample of the cut flowers was dominated by a strong terpenic and fresh note with coumarin side-notes, while the typical odours of the genuine flowers were less impressive." \\+"More than 45 headspace constituents of the **living lime tree flowers** were detected by gas chromatographic-spectroscopic methods; more than 35 of them were identified.

 +Linden nectar extracts contained compounds of fatty acid degradation (nonanal, decanal, tetradec-1-ene), phenylpropanoids (3-(4-methoxyphenyl)propan-1-ol, 3-(4-methoxyphenyl)propanal, 3-(4-methoxyphenyl)prop-2-enal), isoprenoids (vomifolione, vomifoliol, and 3,5,5-trimethyl-4-(3-oxobutyl)cyclohex-2-en-1-one), alkaloids (caffeine, theophylline, a trace of nicotine), and a complex mixture of monoterpenes, among them linden ether and 1,8-cineole. Main components of ripe linden bee honey were benzoic acid and phenylacetic acid, together with two new monoterpenic acids, 4-isopropenylcyclohexa-1,3-diene-1-carboxylic acid and 4-(1-hydroxy-1-methyl-ethyl)cyclohexa-1,3-diene-1-carboxylic acid. \\
