Phytoremediation of iron from red soil of tropical region by using Centella asiatica.

The accumulation and removal efficiency of Fe by Centella asiatica was carried out at various Fe concentrations in soil treatments (0, 50, 100, 150 and 200 mg Fe/kg soil). Iron accumulation in different parts of C. asiatica (leaf, stem and root) was analyzed by atomic absorption spectrophotometer (AAS).

Chamomile (Matricaria chamomilla L.) is a well-known medicinal plant species from the Asteraceae family often referred to as the "star among medicinal species." Nowadays it is a highly favored and much used medicinal plant in folk and traditional medicine.

A novel antimicrobial agent from the leaves of Peltophorum vogelianum (Benth.).

The methanolic extract of the leaves of Peltophorum vogelianum (Caesalpiniaceae) afforded a new phytoconstituent, 2-methoxy-4,5-dihydroxy-1(7,8-dihydroxyethylene)-8-beta-D-glucuropyranoside named as peltophorumyl-beta-D-glucuropyranoside (5), along with four known phytoconstituents, 1-pentatriacontanol (1), friedelin (2), beta-sitosterol (3) and beta-sitosterol-beta-D-glucopyranoside (4), which have not been isolated previously from this plant. Their structures were established on the basis of chemical and physical evidence (IR, 1H-NMR, 13C-NMR, DEPT, HSQC, HMBC and MS). Moreover, compound 5 showed significant antimicrobial activity.

A novel lupene-type triterpenic glucoside from the leaves of Clerodendrum inerme.

A new triterpenic glucoside, lup-1,5,20(29)-trien-3-O-beta-D-glucopyranoside (4), along with three known phytoconstituents: n-octacosane, friedelin and beta-amyrin, has been isolated from the leaves of Clerodendrum inerme (L.) Gaertn. (Verbenaceae).

6,8-Diiodo-5,7-dimeth-oxy-4-methyl-coumarin.

In the title compound, C(12)H(10)I(2)O(4), the meth-oxy groups are twisted considerably with respect to the plane of the aromatic ring [CH(3)-O-C-C torsion angles = -85.9 (3) and -92.8 (3)°].

7,7',8,8'-Tetra-meth-oxy-4,4'-dimethyl-3,5'-bichromene-2,2'-dione.

In the title mol-ecule, C(24)H(22)O(8), the mean planes of the two coumarin units are inclined to each other at a dihedral angle of 79.93 (3)°. The attached meth-oxy groups form torsion angles of 7.

7,7',8,8'-Tetra-meth-oxy-4,4'-dimethyl-3,3'-bicoumarin.

In the crystal structure, the title compound, C(24)H(22)O(8), lies on a twofold rotation axis and the asymmetric unit comprises one half-mol-ecule. The dihedral angle formed by the coumarin unit with the symmetry-related part is 74.78 (14)°.
