At the time of arrival of Muslim community in Sub-Continent Region and due to their settlement in the region Arabic Language has been prevailed and such as the system of its publication and learning has been commenced. Because the directives of Islam and laws are in the Arabic Language as per Quran & Sunna so that it is necessary to learn the Arabic language for the awareness of Islamic directions. So that to achieve the knowledge of Sharia inclu-ding the expertise the peoples of Sub-continent has been achieved the expertise of Arabic language, literature, knowl-edge Ilmul Saraf al-khawa, knowledge of al-ishtiaq & Ilmul Balaghta etc. Moreover it is clarify that Scholar of religious have shown their expertise so that the scholar of Arab have been convinced their expertise. The basic point of service in Arabic Language of Scholars of Sub-Continent that they do not served only to enhance the language but the cause of service was to serve themselves on religious matters and represents themselves on work hard and tried themselves to achieve the better performance of identification of Islam. A positive result and effects have been achieved as a sun shining of Islam is remaining and its waves are enhancing all around the world such as the sun shining of Islam is remained in Arab world such as the publication of literature is also remaining in the Sub-Continent region in the actual shape and saved. Because the Islam will remain till the day of judg-ment and its representatives/workers will born till the date such as the scholars of literatures will also born and they will save the knowledge of Arabic. They will alive till the Day of Judgment.
The current investigation is carried out to detect the pharmacognostic, physicochemical and pharmacological evaluation of leaf, stem bark and root of Ehretia serrata Roxb. andEhretia obtusifolia Hochst. Ex A. DC which belongs to the family Boraginaceae. The morphological study showed that E. serrata is a small size deciduous tree, less than 10 m tall, locally named as puran and punna in Urdu.Its Leaf is simple with oblong shape (5-16 cm long and 2.8-6.5 cm wide), serrulated margins and glabrous surface. E. serrata contains drupe globose type fruit with yellowish green-light color when unripe and black when ripe. Stem bark is irregular with up to 2.5 cm wide, dark brown outer color and whitish golden inner surface color. E. obtusifolia is a deciduous small shrub or small tree up to 6 m tall; straggling or with several branches from the base. The Leaf is oblong-elliptic or oboviate with obtuse apex, entire margins and reticulate venation. Microscopic study of E. serrata showed the presence of conical trichomes and anomocytic type of stomata on both surfaces where as anisocytic type of stomata was observed only on the lower epidermis with stomatal index 36.7μ. Upper surface showed 30.4 μ stomatal index. Other parameter includes palisade ratio (6.4+0.894 per mm2), vein Islet number (19.4+1.79 per mm2), stomata number (21.8+1.78 per mm2) and vein termination number (10.6+1.987 per mm2). A Similar microscopic anatomical study was carried out of leaf of E. obtusifolia and we observed two types of trichomes i.e simple conical trichomes and capitate glandular trichome on both surfaces. Stomatal cluster was observed only on the lower epidermis with three types of stomata i.e anomocytic, anisocytic and hemiparacytic. Other observed parameters were palisade ratio (6.2 + 0.81 per mm2), vein islets number (18.6 + 1.14 per mm2), vein termination number (8.2 + 0.828 mm2), stomatal number (21.8 + 1.78 per mm2) and stomatal index (35.7 + 6.12 μ). Stem bark anatomy of both experimented plants showed clear layers of cork, cork cambium, phloem elements, medullary rays and tracheids, etc. Fruit anatomy of both plants showed a clear distinction between three layers of pericarps and seeds.Powder drug microscopy of leaf, stem bark and fruits of E. serrata and E. obtusifolia was carried out and observed stomata, epidermal cells, fibers, tracheids and vessels, etc. Results of qualitative preliminary phytochemical screenings of examining parts of E. serrata and E. obtusifolia are given, presenting the presence of phenol compounds, starch, protein, reducing sugar, steroids, terpenoids, fats, aldehydes, anthraquinones, glycosides, amino acids, saponins, alkaloids, tannins, phlobatannin. Similarly, results of a fluorescence study of leaf, stem bark and fruit of E. serrata and E. obtusifolia are also given. Results of elemental analysis showed the presence of some essential elements in all examined parts of these two plants. The most abundant elements found in all three parts of E. serrata and E. obtusifolia were Mg, Na, and Fe and which may contribute to analgesic and anti-inflammatory effects of these plants. Proximate analysis of both plants showed carbohydrate, proteins, fibers, fats and moisture in fairly large amounts. The methanolic extracts of E. serrata and E. obtusifolia leaf, stem bark and fruit were non-toxic against Swiss albino mice. Methanolic extract of leaf of E. serrata showed the highest (P<0.01) cytotoxic activity (83.3%) with the LD50 values 15.29 µg/mL at dose level 1000 µg/mL and in E. obtusifolia the fruit methanolic extract showed highest (P<0.01)(80.0%) cytotoxic activity at 1000 µg/mL with an LD50 value of 16.07 µg/mL. All experimented parts of both plants showed non-significant (P>0.05) Phytotoxic activity at all dose levels of 10, 100 and 1000 µg/mL. The anti-oxidant effect of all parts (leaf, stem bark and fruit) of both plants was dose dependent. High (94.1%) DPPH inhibition was shownby stem bark extract of E. serrata at dose level 1000 µg/mL after 60 min and fruit extract of E. obtusifolia (85.01%) at level 1000 µg/mL after 30 minutes. Based on IC50 (µg/mL) stem bark of E. obtusifolia and leaf of E.serrata showed significant values as compared to ascorbate. Both plant methanolic extract was not that much more effective against bacterial strains inhibition. The prominent antibacterial zone (7 mm) was observed in the leaf methanolic extract of E.serrata as compared to reference drug (31.5 mm) at dose level 1000 µg/mL. Similarly, different parts of E. obtusifolia tested against various bacteria which showed no significant results and the most prominent (7 mm) anti-bacterial zone was observed at dose level 1000 µg/mL of leaf extract compared to reference drug (30.2 mm). Toxicological studies showed that both plants are safe for human use. Analgesic effect was found dose dependent and time dependent and all parts of both investigated parts (P<0.05) showed significant results. The highly significant analgesic effect was shown by all experimented parts (P<0.01) at all dose level 100 mg/kg, 200 mg/kg and 300 mg/kg over 60 minutes in E. Serrata except stem bark. Stem bark of E. obtusifolia showed highly significant (P<0.01) at all dose after 60 minutes. Anti-inflammatory effect of all three investigated parts of E. serrata and E. obtusifolia were observed and it is noticed that all parts of E. serrata showed high significancy (P<0.01) at all dose i.e 100 mg/kg, 200 mg/kg and 300 mg/kg after 2 and 3 hours. Similar results were shown by E.obtusifolia. Antispasmodic effects of methanolic extract of leaf stem bark and fruit of E. serrata and E. obtusifolia was tested in swiss albino mice. Stem bark methanolic extract showed highly significant (P<0.01) results at dose of 200 mg/kg and 300 mg/kg. E. obtusifolia causes better relaxation of the smooth muscles at very low concentrations. Leaf extract at dose of 200 mg/kg and 300 mg/kg, fruit at level of 300 mg/kg and stem bark at all dose showed highly significant (P<0.01) results thus providing a scientific proof for its ethnopharmacological use as an antispasmodic drug. The present study has revealed the enormous and different medicinal properties of E. serrata and E. obtusifolia both can be exploited for therapeutic preparations on a commercial scale.
