ATCC issues Certificates of Analysis with cultures. Although ATCC Certificate of Analysis do not meet the specific requirements of ISO Guide 31, they do show that the biological RM culture has been authenticated and/or specific characteristics have been verified. Each ATCC Certificate of Analysis is lot-specific and includes expiration dates, the specific seeds used for propagation, and selected biochemical and morphological characteristics that are indicative of the culture. ATCC also aims to provide a Product Sheet for each microbial culture, with instructions for propagation, special features of the organism, and any imusual observations or properties.

Novel pyranoanthocyanins have also been isolated and identified in blackcurrant (Ribes nigrum) seed using HPLC, 2D NMR and ES-MS. Blackcurrant seeds were extracted with acetone-water (70 30, v/v) and the components of the extract were separated in a polyamide column followed by HPLC-DAD. The new pigments were finally separated in an MCI-HP20 column. The chemical structures of anthocyanins 1-2 and the novel pyranoanthocyanins 3-6 with the pyrano[4,3,2-de]-l-bcn/opyrylium core structure are shown in Fig. 2.110. It was stated that the analytical method developed separated well the novel pyranoanthocyanins [245],... 

Effect of Seed Density. Figure 3 shows the results obtained for batch nucleation runs at 70 C for various seed densities. The seeds used were taken directly from alumina trihydrate bags supplied by Alcoa of Australia Ltd.

In a similar application Thomas et al. (1993) developed a process for the separation of stones and sand particles from coriander seeds using a bed fluidized wifh air. Coriander seeds between 2 and 5 mm in diameter, and with a minimum fluidizing velocity of 0.8ms , were separated from denser stones of a similar size range and from sand parficles ranging in size from 0.3 to 1 mm. Fluidization for 5 minutes was sufficient to effect complete separation.

The test seeds used for the bioassays were Mimosa pudica, Achyranthes aspera, Bidens pilosa, and Crusea calocephala (herbaceous species) Ochroma lagopus and Heliocarpus donell-smithil (arboreal species). 

Radon can be isolated from radium by several methods. An aqueous solution of radium salt such as radium bromide is heated, liberating radon. Radioactive bombardment then decomposes water to oxygen and hydrogen. Radon is separated from the gaseous mixture by condensation in tiny tubes placed in liquid air. The tubes then are sealed by melting. A gold or platinum coating is applied to form the radon seeds used in radiation therapy.

The high amoimt of lipids in morama beans is comparable to the content found in seeds used for production of commercial vegetable oils such as sunflower seed (22-36%) and rapeseed (22-49%) and closely approaches that of peanuts (45-55%) (Belitz et al., 2004 Salunkhe and Kadam, 1989). The amoimt of lipids is twice that of soybeans...

Claims to be able to reliably differentiate between opiate and poppy seed use We ve recently heard (8/2001) that many hair tests now check for more than the NIDA 5, and include at least Cannabis, Ecstasy/MDMA, Cocaine, Opiates, Methamphetamine, Amphetamine, Phencyclidine (PCP), Benzodiazepines, Barbiturates. 

OIL CAKE. The residue obtained after the expression of vegetable oils from oil-bearing seeds, used as cattle feed and fertilizer. 

Because animals do not synthesize either the aromatic or branched-chain amino acids, these materials can be applied to kill unwanted vegetation without causing harm to domestic animals or humans. Certain derivatives can often be selectively applied to combat noxious plants without appreciable harm to crops. More promising, however, is the prospect of using biotechnology to incorporate genes for enzymes specifically resistant to one of the herbicides into seeds used for crop production. 

Oils may contain toxic compounds. For example, Myristicin is the compound that flavors nutmeg and mace it is also found in black pepper and carrot, parsley, and celery seeds. Used in culinary quantities, myristicin is only a flavoring. In massive doses, it causes hallucination. Thujone, the anise-flavored oil in wormwood, caused an epidemic of brain disease in drinkers addicted to the now-banned liquor absinthe. Sassafras contains a toxic oil similar to thujone, which is why it is no longer used to make root beer. Very high doses of menthol, from peppermint, may cause dangerous irregularities in the heart s rhythm (Weiss, 1997)...

Certified reference materials offer the chance to limit the impact of most of the factors described above. They are certified to the mass fractions of the plant materials (typically seeds) used [16]. This makes these standards fully traceable to SI units. The materials are produced under highly standardized and well-characterized conditions and their homogeneity is confirmed. Every analyst calibrating his/her method using these standards will have an analytical system that is traceable to SI units. 

Figure 11.12 shows the relative effects of racemization and seeding on the product purity at the end of the batch. At this time, the supersaturation is depleted and the process path is close to the equilibrium double saturation point on the phase diagram. The results are corrected for the amount of seed used. That is ...
