Inula viscosa Honey

It should be pointed out that at least some of the compounds secreted through the activity of the hair cells are volatile; a specific scent is characteristic in the air of all the Aegean islands on which I. Their cells reacted positively for the same compounds as the primary calluses and produced equally intense staining. Receive exclusive offers and updates from Oxford Academic. Structures or cells with secreting activity were localized and a spectrum of products was histochemically identified within them.

Glandular hair of Salvia officinalis: Yeasts attack a piece of leaf before the callus develops and prior to rapid deterioration Fig.

The fact that almost all the major compound groups detected on the TLC of the viscowa extracts can also be detected in the callus extract and the retention of the cell’s ability to produce secondary metabolites by the second generation of calluses are encouraging factors for the possible industrial production of active compounds from mass-tissue cultures. Spongy parenchyma is rather compact, leaving only a few intercellular spaces Figs 6, 8, Inuula interesting observation on developed callus masses is related to the well-known phenomenon of the clear zone appearing round knula colonies of antibiotic-producing bacteria or fungi when they are approached by expanding colonies of other susceptible micro-organisms.

Active compound extraction would permit conservation of the species in the wild because raw material will originate from the laboratory. Cross-section of a leaf. Botanical Society of Britain and Ireland.

All tissues were viewed with a Zeiss Axioplan optical microscope. Histochemical investigations led to the localization of the synthetically active sites or cells and contributed to the identification of the major compound groups secreted. Their cells are rod-shaped, elongated and virtually transparent prior to staining Fig. This page was last edited on 22 Marchat Even though these reactions could not be localized in certain cellular components of callus cells, it is important that non-differentiated cells retained their ability to synthesize and accumulate secondary metabolites of pharmaceutical value terpenes, steroids, alkaloids.

Multicellular protective hairs have a complex structure Figs 1, 2 being composed of about ten basal cells arranged as a rosette. The use of lead citrate at high pH as an electron-opaque stain in electron microscopy. A new histochemical method for localization of the site of monoterpene phenol accumulation in plant secretory structures.

Ichthyotoxic sequiterpenes and xanthanolides from Dittrichia graveolens.

For these reasons, this species is of major interest for many pharmaceutical industries and a detailed study of its secreting structures is necessary.

In de-osmicated sections from plastic embedded tissue they appear brownish in colour and seem to be trapped among the grey-coloured phenolic inclusions of the vacuole white arrows in Fig.

Figs 4, 5, 6, 8, 10 are leaf cross-sections. The preservation of cellular ultrastructure and enzymatic activity by aldehyde fixation. Application of GC-MS to callus extracts traced only hydrocarbons and compounds of lipid nature, all of them of minor importance, whereas the volatile compounds present in the leaf extracts were not detected.

Histochemical investigation inupa leaves. Calluses produced from leaf-cell cultures were also subjected to histochemical reagents and tested with GC-MS and TLC to investigate their secreting ability compared with that in leaves. Illuminating the systematics of the Spiranthes sinensis species complex Orchidaceae: White arrow in Fig. Dittrichia viscosaalso known as false yellowhead[2] woody fleabaneviscoaa sticky fleabane and yellow fleabaneis a flowering plant in the daisy family.

Some of the compounds investigated in the fresh leaf and all the compounds of callus extracts of Inula viscosa using GC-MS. It contains an essential oil [7] and has been used in traditional medicine since ancient times, especially in the Levantas an astringent.

Antifungal activity of essential oils from leaves of Inula viscosa Asteraceae by Apulian region. Abstract Leaves of Inula viscosa have been used in medicine from ancient times. Identification of the components was based on comparison of their mass spectra with those of WileyNBS Massada, and NST Libraries and to those described by Adams, as well as by comparison of their retention indices with literature values Adams, Retrieved 18 January Email alerts New issue alert.

One adage says that: Terpenes, phenolic derivatives and alkaloids also detected will be extensively investigated in future studies.

The leaves of Inula viscosa possess long protective hairs, numerous viscoa hairs and stomatal complexes on both the abaxial and the adaxial surfaces Figs 14, 5.

Detailed results are given in Table 1. The cell in the middle arrow has been wrecked owing to phenolic leaching from the vacuole. Various types viscpsa inclusions, indicated by the various densities, in the vacuole of this cell.

It is important as food for the caterpillars of certain butterflies and moths, like Iolana iolas.

Conyza major Bubani Jacobaea viscosa L. Flavonoids, the compounds responsible for the antioxidant effects of I. Little-differentiated callus cells are synthetically active and produce, as do its leaf cells, numerous polar compounds that could be of pharmaceutical interest.

Systematics at different levels. Wikimedia Commons has media related to Dittrichia viscosa. Our observations revealed that tissue cultures actually produce anti-fungal factors not found in the leaves or not released from them because the yeasts, in infected cultures, attack the leaves, which deteriorate before producing calluses.
