Jojoba [Simmondsia chinensis (Link) Schneider] is evergreen, perennial and drought resistant shrub belongs to the family of Simmondsiaceae. It is a multipurpose oil seed crop mainly grown in desert regions of world. This plant has unique oil among plant kingdom which is chemically a liquid-wax. The liquid-wax is made up of an ester of long chain fatty acids and alcohols. The liquid-wax is unique in nature because have no traces of glycerine and easily modified via hydrolysis, hydrogenation, halogenation, sulfurization, phosphosulfurization and ozonization techniques. The main uses of liquid-wax in various industries like cosmetics, pharmaceuticals, petrochemicals and lubricants. It is a potential seed oil crop for desert region so it is well known as the gold of desert. The main purpose of this chapter is to review the complete information about this plant so that it can produce and utilized maximally. Moreover, the review focuses on biology, biogeography, physico-chemical properties of jojoba oil and propagation techniques of the plant of desert regions.

SummaryA factor recently described and for which the designation Stuart-Prower Factor is proposed, was investigated. It is detected by the usual Factor VII assay but differs from this factor (Matching experiments with plasma and serum of Owren’s Factor VII deficient patient). Stuart-Prower factor is necessary for the conversion prothrombin-thrombin with tissue thromboplastin as well as for the formation of blood thromboplastin. Therefore lack of Stuart-Prower factor produces abnormal Quick’s prothrombin time (not normalized with Russell’s viper venom [Stypven]), and also abnormal prothrombin consumption, abnormal recalcification time and abnormal thromboplastin generation with serum. Matching experiments with plasma and serum of the patients of Graham and Hougie, Telfer Denson and Wright, and Beaumont and Bernard show that we are dealing with the same defect. Physiological and physico-chemical properties are indicated. The possible relationship between Stuart-Prower factor and Factor X is discussed. A critical review with 59 cases of the so-called Factor VII deficiency is given. Investigation of the family of our patient Delia B. indicates that the mode of inheritance is an intermediate autosomal one.

Particularly interest on herbs and plant extracts is due to their content of active principles with remarkable pharmacological properties. Different vegetal species contain natural antioxidants (polyphenols) used for their dermatological anti-inflammatory and healing activity, justified by their action on free radicals. The aim of this paper was to obtain selected phytopharmaceuticals formulations type gels with an increased antioxidant potential based on a mixture of fluid extracts from seaweeds species in the phylum Chlorophyta, Cladophora vagabunda (L.) C. Hoek, in the family Cladophoraceae, Ulva lactuca (L.) syn. Ulva rigida (L.), in the family Ulvaceae (sea lettuce) and species in the phylum Rhodophyta, Ceramium rubrum C. Agardh, in the famiy Ceramiaceae, frequently presents along the Romanian Black Sea coast. Fluid extracts concentration 10 percent were obtained using cold maceration extraction method, in solvents ethylic alcohol 40 percent and 70 percent. The obtained vegetal extracts were mixed in different ratio and analysed for physico-chemical properties, for the content of total phenols, chlorophylls, cartenoids, flavonoids and antioxidative capacity by photochemiluminescence method (ACL, Analytik Jena AG procedure). The selected mixed fluid extracts with greatest content of polyphenols and antioxidant activity were used for obtaining pharmaceutical forms type gels which were analyzed for the physical-chemical properties appearance, pH, spredability and total antioxidative capacity. Preliminary results emphasized that proposed pharmaceutical forms type gels had an appreciable antioxidant activity correlated with a good stability, an increased polyphenols content and would represent a possible new dermatological anti-inflammatory and healing preparation.

Fracturing under ultrahigh vacuum (UHV, p ≤ 10-9 Torr) produces membrane fracture faces devoid of contamination. Such clean surfaces are a prerequisite foe studies of interactions between condensing molecules is possible and surface forces are unequally distributed, the condensate will accumulate at places with high binding forces; crystallites will arise which may be useful a probes for surface sites with specific physico-chemical properties. Specific “decoration” with crystallites can be achieved nby exposing membrane fracture faces to water vopour. A device was developed which enables the production of pure water vapour and the controlled variation of its partial pressure in an UHV freeze-fracture apparatus (Fig.1a). Under vaccum (≤ 10-3 Torr), small container filled with copper-sulfate-pentahydrate is heated with a heating coil, with the temperature controlled by means of a thermocouple. The water of hydration thereby released enters a storage vessel.

SummaryPhysico-chemical properties of recombinant desulphatohirudin expressed in yeast (CIBA GEIGY code No. CGP 39393) were reinvestigated. As previously reported for natural hirudin, the recombinant molecule exhibited abnormal behaviour by gel filtration with an apparent molecular weight greater than that based on the primary structure. However, molecular weight estimation by SDS gel electrophoresis, FAB-mass spectrometry and Photon Correlation Spectroscopy were in agreement with the theoretical molecular weight, with little suggestion of dimer or aggregate formation. Circular dichroism studies of the recombinant molecule show similar spectra at different pH values but are markedly different from that reported by Konno et al. (13) for a natural hirudin-variant. Our CD studies indicate the presence of about 60% beta sheet and the absence of alpha helix in the secondary structure of recombinant hirudin, in agreement with the conformation determined by NMR studies (17)

Tomato Ketchup

The aim of this study is to use of karkede (Hibiscus sabdariffa L.) byproduct as raw material to make ketchup instead of tomato. Ketchup is making of various pulps, but the best type made from tomatoes. Roselle having adequate amounts of macro and micro elements, and it is rich in source of anthocyanine. The ketchup made from pulped of waste of soaked karkede, and homogenized with starch, salt, sugar, ginger (Zingiber officinale), kusbara (Coriandrum sativum) and gum Arabic. Then processed and filled in glass bottles and stored at two different temperatures, ambient and refrigeration. The total solids, total soluble solids, pH, ash, total titratable acidity and vitamin C of ketchup were determined. As well as, total sugars, reducing sugars, colour density, and sodium chloride percentage were evaluated. The sensory quality of developed product was determined immediately and after processing, which included colour, taste, odour, consistency and overall acceptability. The suitability during storage included microbial growth, physico-chemical properties and sensory quality. The karkede ketchup was found free of contaminants throughout storage period at both storage temperatures. Physico-chemical properties were found to be significantly differences at p?0.05 level during storage. There were no differences between karkade ketchup and market tomato ketchup concerning odour, taste, odour, consistency and overall acceptability. These results are encouraging for use of roselle cycle as a raw material to make acceptable karkade ketchup.
