Composition of Volatile Oil of Iris pallida Lam. From Ukraine

Abstract

Iris pallida Lam kurutulmuş rizom ve yapraklarından elde edilen esansiyel yağın nitel ve nicel bileşimi Ukrayna'dan ilk kez okundu. Gereç ve Yöntemler: Buhar distilasyonuyla elde edilen uçucu yağlar, gaz kromatografisi-kütle spektrometresi ile araştırıldı. Bulgular: Uçucu yağlar, sırasıyla %0.03 ve %0.20 verimle yapraklardan ve köksüzlerden elde edildi. Yağ analizleri yapraklarda 26 bileşen ve rizomlarda 18 bileşenin tanımlanmasına neden oldu. I. pallida yapraklarının uçucu yağdaki baskın terpenler skualen (%6), hekzahidrofarnesilaseton (%8) ve neofitadien (%6'ya kadar) idi. I. pallida rizomlarının temel yağlarının baskın bileşikleri arasında miristik asit (%56), kaprik asit (%14.50), lorik asit (%15.42) ve α-irone (%2.85) bulunmuştur. İris esansiyel yağının ticari kalitesinin en önemli kriteri olarak α-irone ve γ-irone içeriği kabul edilmektedir. β-Damaskenon, skualen gibi bileşikler, ilk kez İris cinsindeki bitkilerde tanımlandı. Sonuç: Ukrayna I. pallida'nın florası, rizomlardan esansiyel yağ için ham maddelerin ek bir kaynağı olarak ve biyoaktif maddeler kaynağı olarak tavsiye edilebilir.

Evaluation of Allelopathic Potentials from Medicinal Plant Species in Phnom Kulen National Park, Cambodia by the Sandwich Method

“…Additionally, many compounds were also reported from the leaf and rhizome of iris essential oil. The major compounds were fatty acids, alkanes, aromatic compounds, sesquiterpenes, and triterpenes [14]; however, its allelochemicals were yet to be reported. On the other hand, Eleutherine bulbosa, known as an exotic ornamental and medicinal plant, is native to South America.…”

“…In this process, chemicals-called allelochemicals-are released from plants that impose allelopathic influences (stimulatory or inhibition) into the environment through volatilization, leaching, root exudation and decomposition of plant residues in soil [12]. Allelopathic substances from either specialized or varying amounts of different plant organs are consisted in a vast array of seemingly disconnected structures and possess different modes of action which are mostly interpreted in ecology as a defence against other plants, pests, or diseases [13,14]. Allelochemicals can also stimulate or inhibit the germination, growth, and development of plants [15,16].…”

The medical importance of Iris pallida – A review

“…Orris oilderived from the dried root, was used as a flavouring in soft drinks, sweets, chewing gum etc. It was much used as a fixative in perfumery, as an ingredient of toothpastes, for the treatment of coughandas breath fresheners [21,[24][25][26].…”

The Comparative Analysis of Carboxylic Acid Composition of Four Iris Species from Ukraine

“…Rhizomes of irises are rich sources of secondary metabolites such as flavonoids, [16,17] isoflavonoids and their glycosides, [9,10,14,15] xanthones, [15,16,18] quinones, [19] triterpenoids, [20,21] carboxylic acids, [22–24] and stilbene glycosides [16] . Recent studies confirmed presence of various secondary metabolites in leaves of species of this genus: xanthones, hydroxycinnamic acids, isoflavonoids, [16,17] flavonoids, [15,16,25] fatty acids, [11] quinones, tannins, saponins and terpenoids [21,26] .…”
