Chamaecyparis obtusa (C. obtusa) is known to have antimicrobial effects and has been used as a medicinal plant and in forest bathing. This study aimed to evaluate the anticariogenic activity of essential oil of C. obtusa on Streptococcus mutans, which is one of the most important bacterial causes of dental caries and dental biofilm formation. Essential oil from C. obtusa was extracted, and its ...

In the course of our research for biologically active constituents from coniferous plants, a chromone derivative (1) and an abietane derivative (2) were isolated along with several diterpenes from Chamaecyparis pisifera. Structures of the new compounds were determined to be 5,7-dihydroxy-2-(1-acetyl-2-methoxycarbonylethyl)-chromone and rel-(8R,10R,20S)-8,10,20-trihydroxy-9(10-->20)-abeo-abieta-...

The biocidal activity of three steam distilled wood essential oils-incense cedar, Calocedrus decurrens (Torr.) Florin; Port-Orford-cedar, Chamaecyparis lawsoniana (A. Murr.) Parl.; and western juniper, Juniperus occidentalis (Hook)--were evaluated against adult Aedes aegypti (L.) (Diptera: Culicidae) and Xenopsylla cheopis (Rothchild) (Siphonaptera: Pulicidae) and nymphal Ixodes scapularis Say ...

It is also commonly mixed with henna (leaves of lawsonia alba) in Africa, Middle East and Indian subcontinent, which is traditionally applied to color palms of hands, soles and feet and to dye hair a dark red shade. 3-5 PPD causes contact dermatitis in susceptible individuals 6 , but when ingested, it causes acute angioedema of face and neck rhabdomyolysis and acute renal failure. 1-5 A case re...

Henna (Lawsonia inermis L.) is a small shrub frequently cultivated in India, Persia, and along the African coast of the Mediterranean Sea. Powdered leaves of this plant, in the form of a paste, are used both as a cosmetic and as a remedy for boils, wounds, and some mycotic infections in certain countries of the Middle East. The antibacterial activity of an aqueous extract of henna leaf and some...

Objectives: The study was carried out to assess the analgesic, anti-inflammatory, and CNS depressant activity of the methanolic extract of  the Lawsonia inermis barks(MELIB). Materials and Methods: Anti-inflammatory effects of MEBLI were studied using carrageenan-induced inflammatory method at the dose of 300 and 500 mg/kg b.wt., p.o. Analgesic activity was measured using acetic acid-induced wr...

A successful protocol was developed for mass propagation of Lawsonia inermis Linn., an important medicinal plant. Multiple shoots were induced in apical and axillary meristems derived from mature explants of L. inermis on Murashige and Skoog (1962) medium supplemented with 0.25 mg/l 6-benzylaminopurine (BA), 0.25 mg/l Kinetin (Kn), 0.5 mg/l ascorbic acid and 3% (w/v) sucrose. The rate of multip...
