[Effect of growth period, storage time and varieties on the contents of main active constituents of Curcuma longa L. in rhizome] [Article in Chinese] Li L, Fu S, Qing S. Chongqing Academy of Chinese Materia Medica, Chongqing 400065. OBJECTIVE: To provide criteria for selection, storage and cultivation of the rhizome of Curcuma longa. METHOD: Field observation and sample analysis on the rhizome. RESULT: The contents of curcuminoids and essential oils in mother and daughter rhizome went up with the progress of plant development. The contents of curcuminoids reached the maximum in early September and early October. The contents of essential oils in mother rhizome reached the maximum in early September. The contents of curcuminoids and essential oils in the rhizome varied with the species and went down with the increase of storage years. CONCLUSION: The rhizome should be collected when leaves of the plant have just withered. The suitable storage time is three years.

[Wound management with coconut oil in Indonesian folk medicine] [Article in German] Sachs M, von Eichel J, Asskali F. Klinik für Allgemein- und Gefässchirurgie, Klinikum der Johann-Wolfgang Goethe-Universität, Theodor-Stern-Kai 7, 60596 Frankfurt am Main. The medical plants which are used to treat wounds and injuries by the ethnic group of Ngada on Flores, an Eastern Indonesian island, will be presented. Additionally, the coconut oil used to treat wounds and to conserve medicinal plants will be analysed biochemically. The people of Ngada use the following plants for wound treatment: seeds of the betel nut (Areca catechu L.), fruits of papaya (Carica papaya L.), leaves of the Indian Hydrocotyle (Centelle asiatica L.), the rhizome of turmeric (Curcuma domestica Val. and Curcumara xanthorrhiza Roxb.), leaves of betel (Piper betel L.). Coconut oil is particularly useful because of its biochemical structure: unlike olive oil and animal fatty tissue, it consists of short-chained and saturated fatty acids. These qualities in coconut oil prevent it from becoming oxidized and rancid, thus making it suitable for the preservation of medicinal plants and for wound treatment.

Essential oil extracted from the leaves of turmeric, Curcuma longa L., was investigated for contact and fumigant toxicity and its effect on progeny production in three stored-product beetles, Rhyzopertha dominica F. (lesser grain borer), Sitophilus oryzae L. (rice weevil), and Tribolium castaneum Herbst (red flour beetle). Oviposition-deterrent and ovicidal actions of C. longa leaf oil were also evaluated against T. castaneum. The oil was insecticidal in both contact and fumigant toxicity assays. The adults of R. dominica were highly susceptible to contact action of C. longa leaf oil, with LD50 value of 36.71 microg/mg weight of insect, whereas in the fumigant assay, adults of S. oryzae were highly susceptible with LC50 value of 11.36 mg/liter air. Further, in T. castaneum, the C. longa oil reduced oviposition and egg hatching by 72 and 80%, respectively at the concentration of 5.2 mg/cm2. At the concentration of 40.5 mg/g food, the oil totally suppressed progeny production of all the three test insects. Nutritional indices indicate >81% antifeedant action of the oil against R. dominica, S. oryzae and T castaneum at the highest concentration tested.

[Growth regularities of yujin (Curcuma longa L.)] [Article in Chinese] Wu H, Yang H, Yin G, Chen S. Sichuan Institute of Chinese Materia Medica, Chongqing. Based on the characteristics of leaf, root and tuber growth as well as dry matter accumulation, the ontogeny of Yujin is divided into 4 stages. The growth and correlation among the leaf, root and tuber as well as accumulation of essential oils and curcumins have also been studied.

The analysis of essential oils and extracts (oleoresins) from seasonings--a critical review. Salzer UJ. A critical review of the analytical methods employed for the determination of the relevant components of seasonings is presented. Where the available methods were inadequate, new ones have been devised. Particular emphasis has been placed on those methods of analysis that provide a rapid and sufficiently accurate appraisal of seasoning extracts and essential oils from seasonings under routine control laboratory conditions. At the same time, the margin of error of these methods has been determined. The individual seasoning extracts were assessed according to the following criteria: (1) essential oil--cardamom, laurel leaves, cloves, origanum (marjoram), sage, and thyme; (2) essential oil and nonvolatile lipids--dillseed, coriander, caraway, mace, nutmeg, pimento (allspice), and celery seed; (3) essential oil and/or pungent ingredients--capsicum, ginger, and pepper; (4) essential oil and/or coloring matter--turmeric (curcuma) and paprika; (5) essential oil and other components--garlic, onion, and cinnamon.
