TimTec Featured Plant Extracts collection gathers extracts from plants with known medicinal properties or the history of the traditional use.
Information is compiled using regional print and online plant registers and reference materials.  

TimTec Plant Extracts is the collection of crude mixtures extracted from different parts of plants sampling the flora of Eastern Eurasia.

Plant Extracts are subdivided into four collections:

1. Featured Extracts from traditionally used plants. The following info is largely available for each extract:

•                 Plant Name  
•                 Botanical Info
•                 Geography
•                 Chemical Content    
•                 Traditional Use and Activity  
•                 Plant Images

2. Extracts available from US stock. About 130 extracts are randomly selected to represent geographical diversity and include different plants and also different parts of the same plants.

3. Custom Extraction from stock material. 2,600 plants (dried material) available for custom selection extraction

4. Custom Extraction from plants to-be-collected. 9,000 plants are on this list.

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.

How Plant Extracts are Collected

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
