Abstract
The pomegranate fruit is one of the most important horticultural products due to the presence of polyphenolic, antioxidant and anti-fungal compounds. In the present study, morphological and phytochemical compounds diversity was investigated in eight Iranian commercial pomegranate cultivars. Fourteen morphological characters and 10 chemical compounds were measured. Based on PCA analysis the most variable morphological characteristics among Punica cultivars studied were the wood surface, the leaf tip, the leaf incision, growth power and rained condition. High-performance liquid chromatograms of chlorgenic acid, caffeic acid, Para Coumaric acid as well as titrable acidity, total soluble solid, total phenolic contents, antioxidant activity in juice and peel of cultivars differentiated the cultivars studied. Comparing the two UPGMA dendrograms of Punica cultivars based on morphological data and chemical contents indicated certain disagreement between them. The correlation between morphological and chemical compounds and geographical distances of Punica cultivars was not statistically significant by the Mantel test. These findings indicate that Punica cultivars studied differ in their genetic content, however, this genetic difference is not correlated with their geographical distance.

Abstract
The aim of this study was to investigate the effect of cofactor-bearing chitosan-coated and non-chitosan carbon nanotubes on induction of apoptosis of cervical cancer HELAcell line by measuring the expression of Bax and Bcl-2 genes as well as cell growth and proliferation. MTT test was used for cell proliferation assay. Expression changes of Bax and Bcl-2 genes were analyzed by Real Time PCR. The MTT results showed that the carbon nanotube coated with caffeic acid carrier chitosan and without caffeic acid carrier and crude carbon nanotube and caffeic acid induce apoptosis and cell toxicity. The results showed that caffeic acid with a chitosan-coated carbon nanotube carrier increased Bax expression and decreased Bcl-2 gene expression, so that the expression ratio of Bcl-2 / Bax compared to free caffeic acid to significantly increase. The results show that the death of cancer cells treated with caffeic acid with chitosan-coated carbon nanotube carries an increase in Bcl-2 / Bax expression ratio and thus induces apoptosis in HELA cancer cells. . Also, the use of caffeic acid as a drug and carbon nanotube-coated carbon nanotube carriers of caffeic acid can be considered as a promising strategy in the treatment of cervical cancer.
