Histochemistry and identification of condensed tannin precursors in root of cotton seedlings. A similar study was carried out simultaneously on the secretory activity of two generations of calluses produced from leaf tissue.

Little-differentiated callus cells are synthetically active and produce, as do its leaf cells, numerous polar compounds that could be of pharmaceutical interest. The nucleus is well preserved.

Various types of inclusions, indicated by the various densities, in the vixcosa of this cell. Glandular trichomes of Calceolaria adscendens Lidl. They can clearly be demonstrated in both light Figs 6, 8 and electron micrographs Figs 12, In vitro propagation of lavandin: Callus cells treated with histochemical reagents refer to Table 1 for details. Arrows indicate compounds present in the leaf yet giving no visible sign in the callus.

Spongy parenchyma is rather compact, leaving only a few intercellular spaces Figs 6, 8, This presupposes that callus cells or cell suspension cultures are able to produce active secondary compounds in the same way as are differentiated cells Zenk,and from which an additional advantage becomes evident. Leaf and callus extracts tested together.

Numerous mitochondria, indicating an energy-demanding cell, and osmiophilic granules in the chloroplast on inual right-hand side. It is an important plant in Catalan traditionoften mentioned in adages and proverbs.

Inula viscosa Honey

Attached to this stem is the swollen edge of a slim, elongated cell. In cross-sections the mesophyll appears compact and bilateral Figs 6, 8. Dittrichia viscosa is a highly branching perennial common throughout the Mediterranean Basin. Eventually, the leaf piece deteriorates.


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. Among the 11 plant taxa recorded to grow wild on the European continent, more than grow in Greece Flora Europaea, and about of them, such as Artemisia annuaAconitus spp. A generalization of the retention index system including linear temperature programmed gas—liquid partition chromatography.

Yeasts attack a piece of leaf before the callus develops inulla prior to rapid deterioration Fig.

Systematics at different levels. Records indicate that about pharmaceutical preparations of plant origin are on the market in the civilized world, although the active compounds used viscpsa their production are extracted from only plant species Phillipson,that c. Basal cells and the conical stem of a protective hair. Synonymy Erigeron viscosus L. Their cells reacted positively for the same compounds as the primary calluses and produced equally intense staining.

It has long, narrow leaves that are pointed at both ends and have teeth along the edges viacosa glandular hairs on the surfaces. From Wikipedia, the free encyclopedia. Figure 24 shows that callus cells produce almost the whole spectrum of polar compound groups detected in the leaves yet in smaller quantities, as the intensity of staining indicates.

Conyza major Bubani Jacobaea viscosa L. Chasing the enzymes of secondary metabolism: Reagents used are indicated with a label in each picture. The leaves of Inula viscosa possess long protective hairs, numerous glandular viscoaa and stomatal complexes on both the abaxial and the adaxial surfaces Figs 1visdosa, 5.


Inula viscosa traditional medicine

All histochemical reagents used for the leaf were also applied to the cultured cells. In vitro morphogenetic potential of various lavandin and lavender clones: 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.

Our observations revealed that tissue cultures actually produce anti-fungal factors not inhla in the leaves or not released from them because the yeasts, in infected cultures, attack the leaves, which deteriorate before producing calluses.

One plant can produce many yellow flower heads each with as many as 16 ray florets and 44 disc florets. The fact that almost all the major compound groups detected on the TLC of the leaf 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 viscoss are encouraging factors for the possible industrial production of active compounds from mass-tissue cultures.

Viscisa callus cells, no stain added. In tissue cultures Fig. View large Download viscpsa. The complex structural features of the secondary metabolites are difficult to synthesize and, despite advances in synthetic chemistry, we will depend upon biological sources for a number of them, including many drugs Pezzuto, Some of the reactions are presented in Figures 18— Phenolics are abundant mainly in palisade cells. Figs 4, 5, 6, 8, 10 are leaf cross-sections.
