It has been reported that several conifers possess cytotoxic activities on some human tumor cell lines. Taxol as a natural cytotoxic compound has been extracted from this family. In a program to screen the cytotoxic effects of natural resources, male and female branchlets, fruit or bark of two different species of Iranian conifers were collected, identified and the cytotoxic effects of their hy...

The commercial essential oils of Citrus aurantium L., Cupressus sempervirens L., Eucalyptus globulus Labill., Foeniculum vulgare Mill. and Thymus vulgaris L., isolated by steam distillation by a company of Morocco were evaluated in terms of in vitro antioxidant activity through several methods. In vitro acetylcholinesterase inhibitory activity was also determined. Citrus limon (L.) Burm. f. oil...

Five Hesperocyparis (Cupressus) abramsiana groves were analyzed by Inter-Simple Sequence Repeats (ISSRs). ISSRs analyses revealed geographical differentiation among the groves (= Silba's subspecies) with the Butano Ridge grove being the most distinct in both ISSRs and terpenoids. Combined ISSR and terpenoid data support the recognition of Hesperocyparis. abramsiana var. abramsiana and Hesperocy...

A new species of conifer was recently discovered in northern Vietnam. In a preliminary phylogenetic analysis of morphological data a possible sister species, Chamaecyparis nootkatensis (D. Don) Spach, was identified; however, because of the presumed phylogenetic remoteness of these two species to the remainder of the Cupressaceae, a new genus-Xanthocyparis-was described to accommodate both spec...

Abnormal' cones found irt Cupressus sempervirens include bisexual cones and double female and male cones. They are very infrequent, but there are individual trees ~th a tendency· to produce· ~\Jch cones. We, suggest that these cones reflect changes in normal hohnonal balance. keY, words: Cupressus sempervirens, bisexilal con~s, cones.
