Determination of Stomatal Index

Deter mination of Stomatal IndexThe Plant material of Viscum capitellatum Smith. parasitism on Dendrophthoe falcata which is itself parasitic on M. indica was collected from Amba Ghat, Kolhapur, westerly Ghat region of Maharashtra from India in November 2009. The collection be lies Latitude 16o 58 0.59N and Longitude 73 48 36.61E at altitude 1100m. The plant specimen (Voucher none 550) was authenticated by Dr. Vinay Raole, Reader, department of Botany, M.S. University, Baroda, India.Pharmacognostical StudyMacroscopical Study68It includes the shape, size, deform, texture, surface and odour of the medicate in crude or powe sanguine form and often sufficient to enable to identify the solely medicates.Microscopical StudyHistochemistryIt gives the mood about the colour reaction of specific chemical reagent towards plant tissues 68. Microscopical images are stipulation in Figure no. 2.Quantitative Microscopy 66-69Transverse sections of scale and stems were obtained by means of a microtome and stained with different staining reagents as per standard procedures 66, 70-71. All observations were performed employ Motic Digital P stiflingomicroscope.histological study of leaves and stem were performed by write uped system 69. Leaves were poached in a 5% aqueous response of NaOH for 5 min while stems were boiled with 10% aqueous ascendent of NaOH for 10 min. After cooling and scrubing with irrigate, pieces were treated with a 25% aqueous solution of chromic sexually transmitted disease for 30 min at room temperature. Washed pieces of both leaf and stem were pressed in between 2 slides and slides coves.Determination of Stomatal NumberThe average out get of stomata per square millimeter of epidermis is termed the stomatal number.Determination of Stomatal IndexThe percentage proportional to the ultimate divisions of the epidermis of a leaf, which has been converted into stomata, is termed the stomatal index.SI = S - 100E + SWhere SI = Stomatal index, S = n umber of stomata per unit area and E = number of ordinary epidermal cells in the same unit area.Procedure 68Pieces of leaf between margin or midrib was cleared and mounted, and the humiliate surface examined by means of a microscope with a 4mm objective and an eyepiece containing a 5mm square micrometer disc. Counts were made of the numbers of the epidermal cells and of stomata wi subjugate a square grid, a cell being counted if at least half of its area lies within the grid. The stomata index was determined for both leaf surfaces. Results pertaining to quantitative microscopical study are given in carry over no. 8.Analytical StudyAsh Value1.1 make sense ashTotal ash gives the idea about the residue obtained after ignition. It consist of physiologic ash obtain by ignition of plant tissues and non physiological ash obtain by ignition of extraneous matter adhering to the surface of Plant. 2 gm of accurately weighed air dried close-grained medicate was taken in silica crucible. Th is silica crucible with drug material was kept in break furnace and fainthearted at temperature 4500C. The material was heated till the white coloured ash and constant burden is obtained. The procedure was performed in triplicate. Result is given in table No. 9.The total ash was measured by subtracting the exercising weight of crucible with ash of drug after ignition from weight of crucible with drug powder before ignition. Percentage of total ash was calculated with character to air-dried drug.Acid insoluble ashAcid insoluble ash gives the idea about the presence of inorganic material such as calcium oxalate be in plant material.The ash obtained in the total ash mode was boiled with 25 ml of 2N hydrochloric virulent for 5 min. Insoluble matter was collected on ash less filter paper (Whatman paper) and washed with hot water. The material retained on filter paper and along with filter paper, was further ignited and weighed. Percentage of dose insoluble ash was calculated with reference to air dried material. Result is given in table No. 9.Water soluble ashThe ash obtained from total ash was boiled with 25 ml water for 5 min. All insoluble matter was collected on ash less filter paper, washed with hot water and ignited for 15 min at the temperature not exceeding 4500C.The percentage of water soluble ash was calculated by subtracting weight of insoluble matter from weight of total ash. The difference between weights re kick ins water soluble ash. Percentage of water soluble ash was calculated with reference to air dried drug. Result is given in table No. 9.Extractive ValueExtraction by cold macerationIt is the process of declivity of crude drugs with closures with several daily shakings or stir at room temperature.1 kg of powdered plant was back downed with 5 lit of methanol by cold maceration method. The press was concentrated on whirligig vacuum evaporator (Roteva Equitron, Mumbai) and further dried in vacuum dryer 73.Successive extraction by using Soxhlet apparatusWeighed accurately 200gm of dried, powered crude drug and kept in a filter paper cover which was already placed in thimble. Then the solvent was slowly poured onto it. The solvent from thimble goes to lower round bottom flask via siphon tube due to the siphoning or syphon cycle. Such 2-3 cycles of solvent were performed and then drug powder was kept for 12 hours with solvent for imbibitions. After 12 hours imbibitions, solvent from flask heated to form vapors. Due to heat the solvent from RBF gets converted into its vapors, and then these vapors pass via placement tube into the condenser where it gets condensed. This solvent dripped again on to drug material, which was placed in thimble. This process was continued till thimble gets filled with solvent and when train of solvent reaches to syphon tube, pulling of whole solvent into the flask is taken place. All this events repeated several times and drug material gets extracted continuously with sweet-smelli ng solvent. This process was performed for 3 days and when syphon solution showed negative screen for phytoconstituents, extraction was completed. Then the heating was stopped and the medley was collected and cooled. Then this mixture was filtered and concentrated by using rotary flash vacuum evaporator. The extract was dried in vacuum dryer and was stored in freeze. Then this marc obtained after favorite ether extraction and subjected again to extraction by following solvents (Table 10) 73.Moisture matter by Loss on Drying2 g of air powdered drug was placed in a silica crucible. Before that, crucible was cleaned and dried and weight of empty crucible was taken. The powder was spread in a thin uniform layer. The crucible was then placed in the oven at 1050C. The powder was dried for 4 h and cooled in a desiccator to room temperature and weight of the cooled crucible plus powder was noted.

The images obtained in triplicate and average figures calculated from 20 readings in each parameter (Table no. 12).Crude Fiber ContentPre-weighed dried powder material was extracted with Petroleum ether (b.p. 40- 600C) using soxhlet apparatus for 8 h. The marc obtained after extraction was utilized for determination of Crude Fiber Content.Crude fiber was investigated by acid-base digestion with H2SO4 (1.25%) and of NaOH (1.25%) solution. The marc after extraction was taken into a 500ml beaker and 200ml of change state H2SO4 added. The content was boiled for 30 minutes, cooled, filtered and the residue washed three times with 50ml of boiling water. The washed residue was further boiled in 200ml of NaOH for 30 minutes. The digest was filtered to obtain residue. This was washed three times with 50ml of boiling water and lastly with 25ml of ethanol.The washed residue was dried in an oven at 1250C to constant weight and cooled in dessicator. The residue was scraped into a pre-weighed porcelain crucible, weighed, ashed at 5500C for 2 hours, cooled in a dessicator and weighed. Crude fiber content was expressed as percentage loss in weight on ignition.
