“…Mexicanolides with a Δ 8,14 double bond usually exhibit potent antifeedant and insecticidal activities against the instar larvae of Brontispa longissima (Gestro). 36 Accordingly, compounds 1−4 were tested for their antifeedant and insecticidal activities against the third-instar larvae of B. longissima by using a previously reported conventional leaf disk method. 34 Moluccensin R (1), 6R-hydroxymexicanolide (3), 26−28 and 2hydroxyfissinolide (4) 29−31 were found to exhibit marked antifeedant activity against the third-instar larvae of B. longissima at a concentration of 1 mg/mL (Table 5).…”

Eight limonoids, named moluccensins R-Y (1, 2, 5-10), and six known compounds, including 6-hydroxymexicanolide (3), were isolated from the seeds of an Indian mangrove, Xylocarpus moluccensis, collected in the estuaries of Andhra Pradesh. The absolute configuration of moluccensin V (7) was confirmed by means of single-crystal X-ray diffraction analysis. The (1)H and (13)C NMR data for 6-hydroxymexicanolide (3) was assigned for the first time, and the 6R absolute configuration established by single-crystal X-ray diffraction analysis. Moluccensin R (1), 6R-hydroxymexicanolide (3), and 2-hydroxyfissinolide (4) exhibited marked antifeedant activity against the third-instar larvae of Brontispa longissima at a concentration of 1 mg/mL. The most potent compound tested was 2-hydroxyfissinolide (4), with an AFC(50) (concentration for 50% antifeedant activity) value of 94 μg/mL at 24 h.

Can Scientific Evidence Support Using Bangladeshi Traditional Medicinal Plants in the Treatment of Diarrhoea? A Review on Seven Plants

et al. 2013

View full text Add to dashboard Cite

Diarrhoea is a common disease which causes pain and may be deadly, especially in developing countries. In Bangladesh, diarrhoeal diseases affect thousands of people every year, and children are especially vulnerable. Bacterial toxins or viral infections are the most common cause of the disease. The diarrhoea outbreaks are often associated with flood affected areas with contaminated drinking water and an increased risk of spreading the water-borne disease. Not surprisingly, plants found in the near surroundings have been taken into use by the local community as medicine to treat diarrhoeal symptoms. These plants are cheaper and more easily available than conventional medicine. Our question is: What is the level of documentation supporting the use of these plants against diarrhoea and is their consumption safe? Do any of these plants have potential for further exploration? In this review, we have choosen seven plant species that are used in the treatment of diarrhoea; Diospyros peregrina, Heritiera littoralis, Ixora coccinea, Pongamia pinnata, Rhizophora mucronata, Xylocarpus granatum, and Xylocarpus moluccensis. Appearance and geographical distribution, traditional uses, chemical composition, and biological studies related to antidiarrhoeal activity will be presented. This review reveals that there is limited scientific evidence supporting the traditional use of these plants. Most promising are the barks from D. peregrina, X. granatum and X. moluccensis which contain tannins and have shown promising results in antidiarrhoeal mice models. The leaves of P. pinnata also show potential. We suggest these plants should be exploited further as possible traditional herbal remedies against diarrhoea including studies on efficacy, optimal dosage and safety.

Ten limonoids, named granatumins L-U (1-10, resp.), were isolated from the seeds of an Indian mangrove, Xylocarpus granatum, collected in the estuary of Krishna, Andhra Pradesh. The structures of these compounds were established on the basis of spectroscopic data. The relative configuration of granatumin L (1) was confirmed by a single-crystal X-ray diffraction analysis. Granatumins L-T (1-9, resp.) belong to the small group of limonoids with an oxygen bridge between C(1) and C(29), while granatumin U (10) is a 28-Me-oxidized mexicanolide. This is the first report of limonoids with an O-bridge between C(1) and C(29) from the Indian X. granatum. The pronounced structural diversity of limonoids from this mangrove might originate from environmental factors.
