The barks and leaves extracts of Canarium patentinervium Miq. (Burseraceae Kunth.) were investigated for cyclooxygenase (COX) and 5-lipoxygenase (LOX) inhibition via in vitro models. The corresponding antioxidative power of the plant extract was also tested via nonenzyme and enzyme in vitro assays. The ethanolic extract of leaves inhibited the enzymatic activity of 5-LOX, COX-1, and COX-2 with ...

Manganese (Mn) oxides are environmentally abundant, highly reactive mineral phases that mediate the biogeochemical cycling of nutrients, contaminants, carbon, and numerous other elements. Despite the belief that microorganisms (specifically bacteria and fungi) are responsible for the majority of Mn oxide formation in the environment, the impact of microbial spe­ cies, physiology, and growth sta...

Linum spp. from section Syllinum are promising for the production of aryltetralin lignans like podophyllotoxin (PTOX) and 6-methoxypodophyllotoxin (MPTOX). MPTOX is a PTOX congener that has cytotoxic activity comparable with PTOX. In this study root cultures of Linum Bungei from section Dasyllinum, L. strictum from section Linastrum, L. album, L. mucronatum ssp. mucronatum and L. nodiflorum fro...

OBJECTIVE To analyze the epidemiology, responsible agents, clinical features, and outcome of white superficial onychomycosis (WSO). DESIGN Retrospective study. SETTING University hospital. PATIENTS A total of 79 patients with WSO seen at the Department of Dermatology of Bologna University from 1994 to 2002. Responsible agents included Trichophyton interdigitale in 58 cases (73%), Trichoph...

This study aimed to develop an automated technique, which is rapid, non-destructive and inexpensive, test for rancidity of nuts. A visible near infrared benchtop hyperspectral camera was used capture images from blanched canarium, unblanched canarium macadamia samples. Support vector machine classification (SVC) PLSR models were developed segregate the pooled spectra nuts predict their peroxide...

The title compound, C(30)H(48)O(3), a triterpene isolated from the resin of canarium schweinfurthiiand, is an isomer of the previously reported triterpene 3α-hy-droxy-tirucalla-7,24-dien-21-oic acid [Mora et al. (2001 ▶). Acta Cryst. C57, 638-640], which crystallizes in the same trigonal space group. The title mol-ecule consists of four fused rings having chair, half-chair, half-chair and envel...
