TimTec Plant Extracts is the collection of crude mixtures extracted from different parts of plants sampling the flora of Eastern Eurasia.
Present advances in screening and separation technologies reveal extracts bioactivity with great efficiency and accuracy. Recently reported method of Direct Screening of Natural Products Extracts Using Mass Spectrometry does not require any preparation or fractionation work. Several hundred crude extracts can be screened per one day. Direct bioaffinity screening mass spectrometry method followed by the use of ligand mass information for mass-directed purification makes screen of crude extracts and identification of active compounds precisely possible.
The collected plant material (plant parts: stems, leaves, flowers, roots, bark etc.) is dried in a ventilated oven at 45 oC for 24 H, and subsequently milled to a fine powder by means of an IKA Universal Mixer M20 (or other type). An amount of 20.0 g of the dried plant powder is weighed in an Erlenmeyer of 100 ml to which 70 ml of hexane (purity grade 99 %) is added (the plant sample has to be submerged with solvent) for pre-extraction. The Erlenmeyer is placed in a sonicator-bath (Branson 8210 or some other type) and sonicated at a temperature 40 oC during 30 minutes. The mixture is filtered using paper filter, followed by washing the Erlenmeyer with 20 ml of hexane and then with 50 ml of hexane. The filtrate is poured in a round-bottomed flask and the solvent is concentrated in vacuo (at about 11 mm Hg) up to 5-10 ml by means of rotavapor, utilizing a water bath at 40 oC. This residue is brought in a 30-ml vessel to let the solvent evaporate. The open vessel is left overnight in a well-ventilated hood in order to evaporate the last traces of the solvent in the hexane pre-extract. The solids, collected on the filter, are broken up and dried in the air overnight in the hood. The dried material is extracted in the same way with methanol-water (90:10). The dried material from the filters placed in an Erlenmeyer of 100 ml to which 70 ml of 90 % methanol is added. The mixture is sonicated as above at 40C during 30 minutes, after which it is filtered, followed by washing the Erlenmeyer with 20 ml of 90 % methanol. The filtrate is poured in a round-bottomed flask and the solvent is evaporated in vacuo completely. The dry 90% methanol extract is dissolved in as little as possible 100 % methanol by using the sonicator-bath and poured in a 30-ml vessel to let it evaporate overnight in the hood.

Red is buy into fashion again this year. You must never forget about the yellow flower when have to mix the color. The Red color must exist in every flower garden. Red flower are also able to attenuate the distances and bring closer the insidious places of the flower garden. The Red can be used in 60 – 70 percents mixed with Yelow, it becomes overwhelming and obsessive when it’s too much. Many red tones send away the monotony: Red- orange, Red-yellow.
Growing your own flower is full luxury, but it’s also a good way to save money. I like flower in the house and comes winter I feel almost need some spring cheer to help me ward off symptoms of sad.flower also remind me that the days are, finally getting longer.I succumb to the bunch of flower from the market,somehow feeling that daffodils from Cornwall are an ethical treat, having not involved so many fossil fuels to growing and transport them.
In recent weeks the weather has been exceptional, a real Pakisatn Summer with extra spice added by the Red Rose.I have loved Red roses for years. They are so easy to grow from seed and can be relied upon to add a dash of red to the border from late August through to the first frosts.
My favourite red rose is Cappucinno. I love it because the flowers are slightly different on each plant with varying hues of yellow, orange through to deep chocolate or should I say Cappucinno!
Many gardeners suffer through the long cold winter, missing the flowers their color,The fragrance, the growth, the warm sunshines and wish desperately for spring. But there is an alternative to the misery to grow indoor flowers garden.
Many of our beloved garden flower do not very well indoors where the light levels are just too low in winter even on the sun of window sills, and many other simply refuse to bloom without specific day length or temperature. This means we must turn to the selected house plants or flowers plants that will servive indoor conditions.
A popular flowering for forcing indoors, gardeners can usually pick narcissus up in ready-to-plants kits as Christmas presents or hostess gifts during the off day season. Paperyellow bulbs flower yellow most of the time, yellow and red varietie can also be found. Fragrant flower will appear within a few short months of planting the bulbs in a shallow dish or container. Paperyellow bulbs do not require a long cooling off period to encourage flowers and will grow fast in a warm, sunny window than a cooler table top.
