callus and suspension cultures of lavandula angustifolia mill. (lamiaceae) were established and the effect of different culture media on growth rate was investigated. terpenoids added to suspension culture to investigate their biotrans-formation. all samples were analyzed by gas chromatography (gc) and gc-mass spectroscopy (ms). octan-1-ol, citronellol, linalool, borneol and geraniol were biotr...

The purpose of the present study was to synthesize some novel terpenoids substituted N-(1Hbenzimidazol-2-yl) hydrazine-carboxamide derivatives for possible antimicrobial activity. The synthesized compounds were tested against a panel of Gram-negative (Gm-ve), Gram-positive (Gm+ve) bacterial and fungal strains. The results of MIC tests against both type of bacteria revealed that compounds 5a and...

Background: β-Hematin (Hemozoin) was synthised inside human erythrocyte by malaria parasite. The parasite avoids the toxic effects by polymerizing heme molecules into insoluble crystalline β-Hematin. C. botrys and A. annua used for the treatment of diseases like malaria, hepatitis, cancers, and inflammations. Objective: Determine of antimalarial and anti-protozoa effects of A. anuuae and C. bo...

A new method for determination of volatile terpenoids in wine is proposed. An off-line solid phase extraction—gas chromatographic method has been used for the determination. The influence of several extraction variables was studied, including the solid phase employed (C-18 versus divinylbenzene-based), eluting solvent (n-pentane, dichloromethane, ethanol and methanol), volume of eluting solvent...

The terpenoids constitute the largest family of natural products; over 22,000 individual compounds of this class have been described (Connolly and Hill, 1991), and the number of defined structures has doubled every decade since the 1970s (Devon and Scott, 1972; Glasby, 1982). The terpenoids play diverse functional roles in plants as hormones (gibberellins, abscisic acid), photosynthetic pigment...
