ABSTRACT: Ficus cyathistipula Warb. growing in Egypt is an evergreen tree, reaching up to six meters high. The macro- and micromorphological characters of the stem, leaf and fruit of the plant have been studied with the aim to find the diagnostic features and pointed towards their identification in both entire and powdered forms: partly united, leafy and conspicuous stipules, numerous ca-oxalate crystals, collateral vascular bundles with group of intraxylary phloem, mucilage and tannin cells, laticiferous vessels were the most significant. A total of 60 RAPD fragments have been recorded when DNA of the plant under investigation was amplified using eleven decamer primers designed for the genetic characterization. Furthermore, proximate analysis for the leaves was carried out to facilitate the detection of the quality and uniformity of the plant where the results (g %) showed a total ash (13.06), acid insoluble ash (0.58), water soluble ash (12.39), crude fiber (38) and moisture content (47.5).

Introduction: Family Moraceae is known as the mulberry family or the fig family. It comprises about 40 genera and 1000 species. They are deciduous or evergreen, monoecious or dioecious shrubs, trees, or rarely herbs with milky latex 1. Some Ficus species are grown for their edible fruits referred to as figs, while others for providing shade and as ornamental plants, all of them possess a white to yellowish sap known as latex 2. Ficus comprises about 800 species of deciduous or evergreen trees, shrubs, herbs, climbers and creepers 3, 4.
Dioecious trees are with male and gall flowers separated from female flowers in different receptacles. The female flowers with short style get consumed by their inhabitant wasp larvae. The long styled female flowers usually do not harbour wasps but produce seeds. In unisexual species, male trees produce no seeds as all female flowers are short-styled and infested by wasp larvae. The wasps entering the female tree syconia are unable to lay eggs as all the flowers are long styled. Thus, the female trees produce seeds 5. The fruit is produced by the union of the cymose inflorescence to form a hollow, fleshy axis bearing the flowers on its inner surface. The young fruit is rich in latex, while no latex is found in the mature ones and the fleshy axis is filled with sugar 6.
Traditionally, certain Ficus species were reported to have hypotensive, antidiabetic, mild laxative, antirheumatic and digestive activities. They have been used as anti-inflammatory in urinary tract infections and as anthelmintic against intestinal parasites 7. Medicinally, Genus Ficus is also well documented for its anti-oxidant, antihepatotoxic, antimicrobial and anticancer activities 8. Ficus cyathistipula Warb. is an ornamental tree widely spread in Tropical Africa 9. The genus Ficus is distinguished by its characteristic fruit 10. Herbal drugs play an important role in health care programs in the developing country, however these drugs aren't accepted because of the lack of standardization, the achievement of the process of standardization can be done by pharmacognostic studies 11. A literature survey indicated that no data is available on the anatomical studies on the plant under investigation. This study includes the morphological and the anatomical features, as well as the DNA fingerprinting of the plant. Proximate analysis was also done which could be useful criteria in quality control for the identity and purity of the leaves of the plant.
MATERIALS AND METHODS:
Plant material:
Samples of F.cyathistipula Warb. were collected during the years 2011-2012 in the fruiting stage from El-Orman Botanical Garden, Giza, Egypt.
Botanical study
Specimens for morphological studies were dried according to standard herbarium techniques and voucher samples (No. 13.5.2013) were deposited at the herbarium of the Department of Pharmacognosy, Faculty of Pharmacy, Cairo University. Anatomical investigations were performed on cross-sections of the fresh samples of the young and old stems, the leaf and the fruit and on air-dried finely powdered samples. The photographs were taken by a Leica DFC500 digital camera.
Genetic profiling:
DNA fingerprinting:
Entire fresh leaves of the plant under investigation were freeze-dried and ground to fine powder under liquid nitrogen prior to DNA isolation 12.
DNA extraction:
The frozen leaves (100 mg) were powdered in liquid nitrogen, lysed with 400μl of lysis buffer AP1. Cell debris, proteins and polysaccharides are precipitated by 130μl of buffer AP2. 1.5 volumes of binding buffer AP3/E is added to promote binding of DNA. Contaminants are removed by two wash steps. Pure DNA is eluted in small volume of low-salt buffer or water 13.
Oligonucleotide primers:
A set of 11 primers were used for RAPD analysis: TTCCGAACCC (OPA-15), GACCGCTTGT (OPA-17), CAATCGCCGT (OPA-11), CCACAGCAGT (OPB-18), TTCGAGCCAG (OPC-01), GTCCCGACGA (OPC-07), GTTGCCAGCC (OPC-19), AATCGGGCTG (OPA-04), GTGATCGCAG (OPA-10), CAGCACCCAC (OPA-13), GTTGCGATCC (OPA-20).
Polymerase Chain Reaction (PCR):
The amplification reactions in 25 μl reaction volume containing 1X PCR buffer, 1.5 mM MgCl2, 0.2mM dNTPs, 1 μM primer F, 1μM primer R, 1 U Taq DNA polymerase and 25 ŋg template DNA were carried out following a thermal cyclic program. PCR amplification was done in a Perkin-Elmer/GeneAmp® PCR System 9700 (PE Applied Biosystems) programmed to complete 40 cycles after an initial denaturation cycle for 5 min at 94ºC. Each cycle consisted of a denaturation step at 94ºC for 1 min, an annealing step at 36ºC for 1 min, and an elongation step at 72ºC for 1.5 min. The primer extension segment was extended to 7 min at 72ºC in the final cycle.
Gel electrophoresis and staining:
Amplified products were analysed by electrophoresis on 1.5% agarose gel and stained with ethidium bromide. A molecular size marker of 1 Kbp was used as standard marker.
Proximate analysis:
Determination of moisture and ash contents:
Proximate analysis of the leaves was carried out by adopting the procedures of the Association of Official Analytical Chemists (A.O.A.C., 2000) 14. The determined analytical standards included the total ash, acid- and water-insoluble ashes, crude-fiber and moisture contents. All values were determined gravimetrically and expressed as % w/w with respect to the air-dried material.

Genetic profiling:
DNA fingerprinting:
The banding profile produced by the eleven decamer primers used in RAPD analysis of Ficus cyathistipula Warb. showed distinguishable bands and illustrated in Fig. 11 and Table 2. A total of 60 different RAPD fragments have been recorded showing 8 bands by each of OPA-11 and OPA-04 primers ranging from (1.25-0.28 Kbp) and (2-0.3 Kbp), respectively, 7 bands by OPC-07 primer ranging from (1.1- 0.42 Kbp), 6 bands by each of OPA-15 and OPA-17 primers ranging from (1.25- 0.42 Kbp) and (1.5-0.28 Kbp), respectively, 5 bands by each of OPB-18 and OPC-19 primers ranging from (1.25- 0.45 Kbp) and (1.6-0.55 Kbp), respectively, 4 bands by each of OPC-01, OPA-13 and OPA-20 primers ranging from (1- 0.4 Kbp), (1.1-0.58 Kbp) and (0.7-0.23 Kbp), respectively and 3 bands by OPA-10 primer (1.5-0.7 Kbp). The analysis of RAPD data, under the experimental conditions, can thus be helpful in the control analysis for differentiation and quality assurance of the plant.

Proximate analysis:
The results (g % w/w) of proximate analysis of Ficus cyathistipula showed a total ash (13.06), acid insoluble ash (0.58), water soluble ash (12.39), crude fiber (38) and moisture content (47.5).

CONCLUSION: A study on Ficus cyathistipula Warb. growing in Egypt was performed: It included the botanical identification, the genetic characterization and the determination of total ash, acid insoluble ash, water soluble ash, crude fiber and moisture content. This is the first report on authentication and quality control of the plant.
