Pandya D J, Desai T R,  Nadpara N P, Mehta H A, Modi A M
Bombax insigne Linn. syn. Salmalia insignis (Family – Bombacaceae) is found commonly in India. No detailed pharmacognostic study or establishment of quality parameters has been done on any species of Bombax. The present investigation deals with the qualitative and quantitative microscopic evaluation of the leaf material and establishment of its quality parameters, including physicochemical and phytochemical evaluation. Chief characters of transverse section include primary and secondary vascular bundles surrounded by pericyclic fibres and a sheath of calcium oxalate cluster crystals. Chief characters of powder include xylem vessels having reticulate or annular thickening, pericyclic fibres, calcium oxalate prisms and clusters, and starch grains. Various physicochemical parameters were also established. Phytochemical screening revealed the presence of many therapeutically important classes of phytoconstituents such as alkaloids, flavonoids, phenolics, cardiac sterols, triterpenoids, saponins and carbohydrates. Such a study would serve as a useful tool in standardization of the leaf material, isolation of medicinally important phytoconstituents, performing pharmacological investigations and ensuring quality formulations in the future. It would also help in distinguishing the plant material of Bombax insigne from its related species, Bombax ceiba.

7. Anti-ageing Ability of Terminalia species with special reference to Hyaluronidase, Elastase inhibition and collagen synthesis In-vitro.
Satardekar K V, Deodhar M A
Hydroalcoholic extracts prepared from bark of Terminalia arjuna and dried fruit rinds of Terminalia chebula were examined for their effects on enzyme Hyaluronidase and Elastase activity. The extracts were also studied for the effect on fibroblast proliferation and collagen synthesis in vitro. Both the extracts showed to inhibit enzyme Hyaluronidase and Elastase in a dose dependent manner. In addition to their antielastase and antihyaluronidase effect, the same concentrations of the extracts also stimulated fibroblast proliferation and synthesis of total soluble collagen in vitro. These results suggest potential of Terminalia extracts for facilitating delay in skin aging. These extracts not only provide an active ingredient that inhibits hyaluronidase and elastase enzymatic activities, but also to provide the necessary supplies for the cells to maintain and promote their proliferation and to produce their constituents like collagen.

Chaulya N C, Haldar P K, Mukherjee A
In this study, the methanol (MeOH) extract of rhizome of Cyperus tegetum Roxb, belonging to the family Cyperaceae was prepared by successive extraction procedure (petroleum ether, chloroform, methanol) in Soxhlet apparatus and subsequently, the extract was evaluated for its phytoconstituents and pharmacological activity. Comparatively, higher yield (5.4%) of methanol extract was obtained. Phytochemical tests revealed the presence of alkaloid, glycosides, proteins, amino acids, phenolic compounds, flavonoids, tannins and saponins in the extract. The methanol (MeOH) extract of the rhizome of was used to evaluate the pharmacological properties. The extract does not possess either anesthetic or paralysing effect on test animals but spontaneous motor activity is significantly reduced by the extract. When associated with pentobarbitone sodium or diazepam, the MeOH extract facilitates sleep inductin and increases total sleeping time .These observation suggests that the rhizome of C tegetum has pharmacological properties similar to those of sedatives.

Neergheen V S, Bahorun T, Pugo-Gunsam P,  N Foong Lin D, Ramful D, Aruoma O I
The surge of interest in traditional medicine has prompted research into the phenolic composition and antioxidant activity of Adansonia digitata, Catharanthus roseus, Eugenia uniflora, Phyllantus emblica and Terminalia arjuna which are commonly used as traditional remedies against cardiovascular diseases in Mauritius. The polyphenolic profiles of these 5 herbal preparations (prepared according to traditional medicine sellers’ recipe) were screened. HPLC analyses showed that the plant extracts had complex flavonoid profiles with interesting amounts of quercetin, myricetin and kaempferol conjugates. Flavan-3-ol derivatives such as (+) catechin, (-) epicatechin, catechin gallates, procyanidins B1 and B2 were identified in most preparations. The highest total phenolic (34.9 ± 0.92 mg/g FW) and proanthocyanidin (15.0 ± 0.416 mg/g FW) contents were measured in T.arjuna whilst E.uniflora had the highest flavonoid composition (7.8 ± 0.04 mg/g FW). The antioxidant and free radical scavenging potential were evaluated using trolox equivalent antioxidant assay (TEAC), ferric reducing antioxidant power (FRAP), scavenging of hypochlorous acid, deoxyribose assay and inhibition of microsomal lipid peroxidation. T.arjuna extract exhibited the most powerful antioxidant capacity in the systems studied with a TEAC value of 306.92 ± 2.37 µmol/g FW and calculated IC50s of 1.5 ± 0.09 mg/ml and 0.2 ± 0.01mg/ml in scavenging hypochlorous acid and in inhibiting microsomal lipid peroxidation respectively. The antioxidant activities correlated strongly with the total phenolic content of the plant extracts.

Calycopteris floribunda Lam, (Combretaceae) a scandent woody shrub. The present study was conducted to evaluate the Hepatoprotective activity of chloroform fraction and methanol stem extract of Calycopteris floribunda (CF) against carbon tetrachloride (CCl4) induced liver damage in Wistar albino rats. Chloroform fraction and methanolic extract of CF (100mg/kg, 200mg/kg .p.o.), were administerd respectively, Silymarin (25 mg/kg.p.o.) was given as reference standard. The stem extracts were effective in protecting the liver against the injury induced by CCl4 in animals. This was evident from significant reduction in serum enzyme, Serum glutamic oxaloacetic transaminase (SGOT) and serum glutamic pyruvic transaminase (SGPT), Alkaline phosphatase (ALP) and Total bilirubin (TB).Various pathological changes like centribular necrosis and vacuolization were observed in CCL4 treated rats, which were significant protective activity in groups treated with CF and silymarin. It was concluded from the study that chloroform fraction and methanolic extract of CF possess hepatoprotective activity against CCl4 induced hepatotoxicity in rats.
