Initial isolation and characterization screens have been carried out on the jamaican ball moss (Tillandsia recurvata L.) plant producing a novel complex gly-cosidic compound. This complex glycoside may be responsible for the promising anti-cancer and anti-inflammatory properties of this ball moss plant. A combination of supercritical fluid processing and chromatographic purification was used to produce the isolate. LC-MS analysis showed the presence of a compound with a molecular weight of ~800 and mass spectral (MS-MS and MS-MS-MS) data indicate that this compound may be a glycoside with a molecular mass of 1601.1 Da (negative ionization mode) and possibly contain up to two sialic acids, based on the doubly-charged state of the molecule at neutral pH conditions. 2D-TOCSY NMR spectrum lends evidence to the presence of at least one likely amide to aliphatic proton correlation, indicating the presence of a sialic acid moiety. The main structure of this therapeutic compound appears similar to a soyasaponin.

在室内条件下,测定了14种塑料配方(4种聚乙烯,1种聚丙烯,1种聚酯,2种聚酰胺,1种聚氨基甲酸酯和5种改性聚氯乙烯)对矛颚家白蚁和台湾家白蚁蛀蚀的易感性,并主要与硬度和光洁度联系起来。总的说,矛颚家白蚁造成的损害比台湾家白蚁严重,尽管前者的存活率较低;但是对某些配方来说,受台湾家白蚁的蛀蚀,表现为比矛颚家白蚁更为易感。

Cola acuminata also known as the bissy nut extract was originally endemic to Africa but is now present in a number of tropical countries including jamaica. Despite its rich history of ethnomedicinal use and promising bioactivity, there still exists limited research on this plant. Exploring and compiling the ethnomedicinal usage, identified bioactivities and isolates of C. acuminata will prove useful in steering future directional research with the hope of reaping the plant’s full beneficial properties. The plant’s traditional use encompass;cancer treatment, an antidote for poisoning, suppressing one’s appetite, increasing alertness, treating migraine and motion sickness, obtaining a state of euphoria in addition to being used in certain traditional practices. Because of the plant’s copious ethnomedicinal use, researchers were led to believe that the low incidence of prostate cancer evidenced amongst Asians could be as a result of phytochemicals present in the bissy nut. Research conducted in our lab confirmed the anti-cancer potential of the plant and recent research has identified a number of secondary metabolites present in C. acuminata which could be responsible for the observed bioactivities. The plant has also shown promise as an anti-microbial agent. This paper confirms the efficacy of the bissy nut plant both as an ethnomedicine as well as warranting further research that may prove useful both in the pharmaceutical and nutraceutical industries.
