Ninety solvent extracts (n-hexane, dichloromethane and methanol) obtained from the leaves, bark and stem of 13 Sri Lankan Rubiaceae and two Sri Lankan Meliaceae plants have been screened for antibacterial and antifungal activities. Morinda tinctoria, Mussaenda frondosa, Psychotria gardneri and Psychotria stenophylla displayed the widest spectrum of antibacterial activity.

Tryptanthrin (1), indole-3-acetonitrile (2) and p-coumaric acid methylester (3) were isolated from the aerial parts of Isatis tinctoria L. The compounds show insecticidal and anti-feedant activity against termites (Reticulitermis santonensis), insect preventive and control activity against larvae of the house longhorn beetle (Hylotrupes bajulus) and fungicidal activity against the brown-rot fun...

The organic extract of the plant Maclura tinctoria exhibited moderate anti-HIV activity. Seven prenylated phenolic derivatives were isolated from the active fractions and characterized by spectroanalytical methods. New compounds macluraxanthone B (1), macluraxanthone C (2), and dihydrocudraflavone B (8) were identified.

Technol., 2005, 27(Suppl. 2) : 455-467 The stems of Arcangelisia flava, Coscinium blumeanum and Fibraurea tinctoria, collectively known in southern Thailand as Khaminkhruea, w...

Arbuscular mycorrhizal fungi (AMF), a special microorganism can connect soil and a plant directly, plays an important role in environmental remediation [1]. When the plant is in the heavy metal adversity, mycorrhizal association can enhance the resistance to the metals of plants [2]. Chen et al. [3], reported Cu uptake by four kind of mycorrhizal plants including two native plant species, Coreo...

We prove many new cases of the Inverse Galois Problem for those simple groups arising from orthogonal groups over finite fields. For example, we show that the finite simple groups Ω2n+1(p) and PΩ4n(p) both occur as the Galois group of a Galois extension of the rationals for all integers n ≥ 2 and all primes p ≥ 5. We obtain our representations by studying families of twists of elliptic curves a...

Wrightia tinctora is a tree widely used by the peoples of Tamil Nadu as a traditional medicine for pain and inflammations. Latex form the plant especially from leaves is directly applied on inflammation. This plant is very closely related to other species of Wrightia and hence pharmacognostical and preliminary phytochemical studies of Wrightia tinctoria leaves were carried out.

The essential oil (EO) of Cota tinctoria var. was analyzed using GC-FID / MS. A total 51 compounds were determined from this taxon, accounting for 99.79% in hydrodistillation. Monoterpenes the primary chemical class volatile organic EO (36.1%, 13 compounds). Borneol (18.1%), camphor (14.9%), and β-pinene (11.3%) major components C. tinctoria. antimicrobial activities n-hexane, acetonitrile, met...
