Ficus carica Linn. (Syn: Ficus sycomorous; family: Moraceae) is grows in tropical and subtropical regions of India, used for varity of purpose in traditional medicine. The usefulness of this plant is scientifically evidenced, and different biologically active phytoconstituents were isolated form plant. But no reports are available on morphoanatomy, and phytochemical studies, hence present attempt was undertaken to investigate the microscopical and preliminary phytochemical studies. The study revels the midrib is biconvex and lamina is dorsiventral, shows presence of nonglandular trichome, anomocytic stomata, prismatic calcium oxalate crystals. It shows presence of steroids, triterpenoids, cumarines, flavanoids and glycoside.
Key words: Ficus carica, Morphoanatomy, Phytochemical studies.
Ficus carica Linn. (Syn: Ficus sycomorous; family: Moraceae), which is commonly referred as "Fig", grows in tropical and subtropical regions of India (Anonymous, 2002). In traditional medicine the roots are used in treatment of leucoderma and ringworms and its fruits which are sweet, have antipyretic, purgative, aphrodisiac properties and have shown to be useful in inflammations and paralysis (Kirtikar, 1996; Nadkarni and Nadkarni 1995). F. carica has been reported to have numerous bioactive compounds such as arabinose, -amyrins, - carotines, glycosides, -setosterols and xanthotoxol (Gilani et al., 2008; Vaya and Mahmood, 2006, Ross and Kasum, 2002.). Earlier chemical examination of this plant have shown the presence of psoralen, bergapten, umbelliferone (Seong-Kuk et al., 1995; Louis et al., 2000), campesterol, stigmasterol, fucosterol, fatty acids (Jeong and Lachance, 2001. ), 6-(2- methoxy-Z-vinyl)-7-methyl-pyranocoumarin and 9,19-cycloarlane triterpenoid as an anticancer (Weiping et al; 1997, Weiping et al; 1997.) and antiproliferative agent: 6-O-acyl--Dglucosyl --sitosterol (Shai et al; 2001), calotropenyl acetate, and lupeol acetate (Saeed and Sabir, 2002).
In addition, several therapeutic effects have been shown for different parts of Ficus carica, such as hypoglycemia[Serraclara et al; 1998], cancer suppressive[Rubnov et al; 2000.], anthelmintic [De-Amorin et al; 1999], hypotriglyceridemia [Asadi et al; 2006, Perez et al; 1999a,] hypocholestrolemia[Perez et al; 1999b] and bovine papilomatosis [Hemmatzadeh et al; 2003]. The chloroform extract obtained from a decoction of Ficus carica leaves improved the blood cholesterol status in streptozotocin induced diabetic rats[Canal et al; 2002].
This study was aimed at providing the pharmacognostical standards of F. carica (figs) which will be helpful for distinguish it from other species of Ficus.
Materials and Methods
<![if !supportLists]>1. Plant material collection
The plant material was collected from Botanical garden of R. C. Patel Institute of Pharmaceutical and research, Shirpur, Dhule, India. in Oct 2009. The plant was authenticated (RCP-10) and speciman herbarium were preserved at institute herbarium library. The leaves part were separeted form other parts, washed, cleaned and dried for further use.
<![if !supportLists]>2. Analysis
The external leaf morphology was observed and studied. Fresh mature leaves transverse and longitudinal freehand sections were taken. Whereas dried leaf powder material was used for the determination of ash values, extractive values, and phytochemical constituents. All the reagents used were of analytical grade obtained from Sigma Chemical Co, St. Louis, USA or Fine Chemicals Ltd., Mumbai, India. The results were registered by botanical illustration and photos taken by means of the Motic digital microscope (Motic instrument Inc, Canada) fitted with 1/3 CCD camera imaging accessory with motic image 2000 image analysis software.
Results and Discussion
Ficus carica (Fig. 1) has simple leaves, broadly shape, acute apex and subcordate base, more or less irrgular deeply cut into 3 5 palmate, coarsely irregular margin, measuring 618 cm long and 515 cm wide, petiolate. The lamina texture is rough and the venation is multiconvergent reticulate. In transection (Fig. 2A), the blade epidermis is single-layered (Fig. 2A) and coated with a thin and smooth cuticle. The epidermis shows presence of anomocytic stomata (Fig. 2B), Non-glandular trichomes occur predominantly on leaf epidermal cell surface. The mesophyll is dorsiventral, consisting of about two layers of palisade parenchyma and four strata of spongy parenchyma, prismatic crystals of calcium oxalate are seen The midrib (Fig. 3A and B), in transverse section, is biconvex. The epidermis is uniseriate and has non-glandular trichomes similar to the blade. They are seldom unicellular and uniserrate. The trichome apex is acute and pointed (Fig. 3B). Adjacent to the epidermis, angular collenchyma occur, comprising approximately eight to ten rows on the dorsal side and twelve to fourteen on the ventral one. Embedded in the ground parenchyma, one to two collateral vascular bundles arranged nearly as a closed arc are present. The calcium oxalate prisms are found in spongy parenchymatous tissue.

<![if !supportLists]>b) Fragments of paranchyamatous tissue containing spiral vascular strands measures 25 48 micron in diameter. (fig 3, ii).
<![if !supportLists]>c) Numerous anomocytic stomata meaning thereby that the cells surrounding the stomatal pores are irregularly arranged. (fig 3, iii).
<![if !supportLists]>d) The prismatic calcium oxalate of 7 10 microns in diameter are less abundant and observed as free or in fragments of parenchymatous cells. (fig 2, iv).

The different histo-chemical color reactions were performed on the leaf transverse sections to differentiate the different cell compositions and identification (Trease and Evans, 1986) and results were given in Table 1.

+++ High, ++ Moderate, + Slight, - Negative.
Behavior of leaf powder with different chemical reagents was studied to detect the presence of phytoconstituents with color changes under daylight by reported method (Pratt and Chase, 1949) and the results were shown in Table 2.

Total ash, acid-insoluble ash, water-soluble ash, and sulphated ash values of the fruit powder were done as per the reported methods (Anonymous, 1985) and the results are tabulated in Table 3.

Extracts were prepared with various solvents by reported method (Kokashi et al;1958). Percentages of the extractive values were calculated with reference to air-dried drug (Table 5). Color and consistency of extracts (Pratt and Chase, 1949) are given in Table 4.

All the leaf extracts are examined in daylight, short and long UV to detect the fluorescent compounds by the reported method (Kokashi et al; 1958). The observations are given in Table 5.

Freshly prepared leaf extracts were tested for the presence of phytoconstituents using reported methods (Farnsworth, 1966) and the results are given in Table 6.
