Achiwa s procedure has been utilized by several authors toward the synthesis of cucurbitine, an aminoacid extracted from pumpkin seeds which share structural features with arginine. Different precursors have been used in chiral and achiral synthetic pathways. First, cucurbitine methyl ester was obtained from an a-amino acrylate.424 Other substituted acrylates were tested and 3,3-dimethyl-2-aminocarboxylate did not react at all. 

Herbal remedies hold a different place in medical practice in many European countries than in the United States. One of the most dramatic examples of the difference is in the treatment of benign prostate disease. This very common condition affects about 25 percent of men in their forties and nearly 80 percent of men who are over 70. In Germany, several hundred million dollars are spent annually on prostate remedies, with 80 percent of that spent on herbal medications. Herbal medications dominate the market for treating nonmalignant prostate disease. They have very few side effects and cost per dose approximately 20 to 35 percent of what synthetic drugs do. Treatment with herbal preparations typically costs under a dollar a day. Four of the most popular in Germany are extracts from the fruit of the saw palmetto, pumpkin seeds, rye pollen extract, and nettle root. 

Several solvents and solvent mixtures have been used for the extraction of tocols. Hexane and a mixture of ethanol and hexane were used to extract tocols from food samples (Kramer et al., 1997 Sundl et al., 2007), acetone from microwave-oven-dried leaves (Gomez-Coronado et al., 2004), methanol from cereal grains (Michalska et al., 2007), and a mixture of methanol and chloroform from pumpkin seeds (Stevenson et al., 2007). A mixture of chloroform and methanol gave 10 20% greater amounts of tocopherols from fresh tree nuts than hexane, indicating that the mixture was more efficient than hexane...

The common pumpkin seed has been extensively studied for its beneficial effect on prostate health. Seed extracts inhibit 5-alpha-reductase conversion of testosterone to dihydrotestosterone. The mechanism of action seems to be different from that of saw palmetto, nettle root, or pygeum. Researchers speculate that betasitosterol (a phytosterol) competes with androgens, thus decreasing esposure of the prostate to hormonal stimulation. Eating pumpkin seeds (1 to 2 ounces per day) or taking gel capsules (2 to 4 per day) has shown benefits in reducing inflammation and other prostatic symptoms.

Salgin and Korkmaz [5] considered the SCFE of pumpkinseed oil. They found that the oil they obtained did not differ significantly from that obtained using hexane extraction in terms of fatty acid content. They came to the conclusion that SCFE is a green process and can be used to recover healthy oil from pumpkin seeds. 

In German phytomedicine, the dried rhizome and its preparations were used for conditions of nervous anxiety, stress, and unrest. Combined with pumpkin seed oil, kava extracts have been used in the treatment of irritable bladder syndrome. Use is contraindicated during pregnancy, lactation, and depression. The German monograph on the plant also notes that continuous use can cause temporary yellow discoloration of the skin, hair, and nails, or rare allergic skin reactions. May interact with alcohol, barbiturates, and other psychopharmaceuticals or interfere with operation of machinery or vehicles (weiss). ... 

Oil from powder of microcapsules was extracted with cyclohexane. The amount of extracted oil from powder of microcapsules containing different oils as a function of SDS concentration in emulsion is shown in Figure 27. In microcapsules containing sunflower and mixture linen seed/sunflower oil (0.2/0.8) the lowest amount of extracted oil was found in the HPMC/SDS interaction region, at 0.35%SDS, which indicates a compact shell which hinders oil extraction from microcapsules. On the other hand, the amount of extracted pumpkin seed oil increases on increase in SDS concentration, indicating more permeable shell of microcapsules. It was shown that oil influences microencapsulation process and thus properties of microcapsules. Therefore, nature of it should be considered as an important parameter during the microencapsulation process by the presented method.

Information on transamination in plants is very incomplete and chiefly of a qualitative nature. Apart from observations by Kritzmann (114, 117) on the transformations GL— AL and AS— AL in pea, lupine and pumpkin seedlings, the presence of transamination activity in plants, especially in Leguminosae, has been demonstrated by Euler and associates (1) and by Virtanen and Laine (160, 162). Cedrangolo and Carandante (53) report that transamination reactions are 1.5-2.5 times more active in dialyzed extracts from seeds and sprouts of Graminaceae than of Leguminosae, but the reported reaction rates were very low and the analytical methods are...
