Benefits of technology

The invention provides a method for reducing the risk factors for cardiovascular disease, treating atherosclerotic plaque, protecting LDL particles from oxidative damage, maintaining normal blood HDL-cholesterol concentrations, decreasing high blood pressure, and maintaining normal haemostatic function. The method includes administering an effective amount of a composition made from olive cells grown in vitro. The olive cells can be derived from various parts of the olive tree such as the cross section, pulp, seed, petiole, or leaf.

Problems solved by technology

Since large scale processes cannot be performed by the same means as small scale processes, specific processes for the large scale production of materials must be designed, even if small scale processes exist.
However, the use of synthetic processes does not provide the natural ingredients along with the active ingredients, which sometimes contribute to the efficiency of the formulation.
However, when plants containing polyphenols, for example, are extracted, the final product may be bitter.
Also, only certain parts of the plant may be successfully extracted since only they contain the desired amounts of the active ingredients.
Small scale processes for the preparation of fruit cells are known in the art; however, large scale processes are more difficult to design since they tend to amplify the production of the primary metabolites, while minimizing the productions of the secondary metabolites.
Since active ingredients, such as polyphenols, are secondary metabolites their production in large-scale processes is complex.
However, it has been shown that the therapeutic effect of fruit extracts is dependent on species, location, year (annual climate), processing etc. and therefore reliance on natural fruits as a source of these regulatory compounds does not lead to a homogeneous or consistent supply of material.
Furthermore, fruits are often contaminated by residual fungicides, pathogens, pesticides and pollutants.

Generation of Olive Cell Lines (Calli) and Suspension Cultures in Erlenmeyer

1. Material and Methods

Plant Material

[0151]Olive cell culture was initiated from olive fruits (Olea europaea L.) of Nabali, Manzanilla, Souri and Barnea cultivars, including all leaves, petioles, fruits and kernels.

Establishment of Calli from Olive Explants

[0152]Olive plant parts: young leaves and their petriols, immature fruits (about 6 weeks from flowering) and kernels from immature olives were rinsed under running water and sterilized by agitation in 70% ethanol for three minutes and then 3% Na-hypochlorite solution for 20 minutes, followed by three washes in sterile water. Plant parts were dried under sterile conditions and further dissected into ˜0.5 cm sections.

[0153]Olive plant explants were plated on MS Murashige and Skoog medium basal medium (Table 1B) supplemented with sucrose and various combinations of the auxines 2,4-dichlorophenoxyacetic acid (2,4-D), 1-naphthaleneacetic acid (NAA) and the cyto...

Expression Polyphenolic Compounds in Olive Cell Calli

Materials and Methods

[0160]Polyphenols extraction for HPLC analysis: Fresh olive Callus cell cultures were extracted for analytical determination of polyphenol content in the olive culture. About 1 gr of callus was harvested and kept at −20° C. for at least 16h before analysis. The callus was extracted by 80% methanol / water solution in a ratio of 0.4 ml methanol per 1 gr of cells. The suspension was sonicated for 10 minutes at 30° C. in a sonicator. The solution was centrifuged and the supernatant was re-centrifuged, filtered through a 0.45 μm filter and used for the HPLC analysis.

[0161]Olive tissues (fruits and leaves) were crushed under liquid nitrogen and extracted as described above, the extract was analyzed by HPLC and used as a reference for olive polyphenols content.

[0162]Olive calli extract was analyzed by LC-MS. The method is described in: Food Chemistry 138 (2013) 1381-1391.

[0163]Olive calli samples were extracted in met...

[0169]Scale Up of Olive Culture in Bioreactors and Testing of the Total Amount of the Polyphenols, including, Hydroxytyrosol, Tyrosol, Oleuropein, Verbascoside and Pinoresinol Content in Olive Cells Grown in Large Scale Bioreactors

Materials and Methods

Stage 1: Cells are Prepared and Grown as Described in Example 1.

Stage 2: Small Scale Bioreactor

[0170]Small scale bioreactor culturing is performed by inoculating a 7 to 16 old day cell suspensions grown in the Erlenmeyer of Stage 1 into a 4-8 liter disposable bioreactor at 25+5° C. The cells were grown in the suspension under continuous fluorescent light (1000 1×) in a growing medium containing modified MS supplemented with sucrose 1-6% and the Kinetin, 2,4,D, NAA, BA, 2iP and casein hydrolysate or a combination thereof

[0171](pH 4.0-6.0)-. The cells were sub-cultured every 5-21 days.

Stage 3: Large Scale Bioreactor

[0172]The cell suspensions grown in a small scale bioreactor were inoculated into a 30-50 liter disposable bioreactor. The c...

Description

FIELD OF THE INVENTION[0001]The invention is directed to olive derived cell cultures, a process for the large scale production of such cell cultures, as well as methods of using the same.BACKGROUND OF THE INVENTION[0002]Large scale processes are known in the art and are necessary for the industrial production of various materials. Since large scale processes cannot be performed by the same means as small scale processes, specific processes for the large scale production of materials must be designed, even if small scale processes exist.[0003]Nutraceuticals are sometimes prepared using synthetic processes that provide the desired active ingredients, e.g., polyphenols, which are naturally found in fruit cells. However, the use of synthetic processes does not provide the natural ingredients along with the active ingredients, which sometimes contribute to the efficiency of the formulation.[0004]Other types of nutraceuticals are prepared from the natural plants; however, all known large ...
