Two new species of Bulbophyllum (Orchidaceae) are described: B. sphenoglossum (sect. Lemniscata) and trigonanthum Reptantia). Both occur in Thailand.

An immunomodulatory protein (IPAF) was purified and cloned from Anoectochilus formosanus, an Orchidaceae herbal plant in Asia. The major targeting immune cells of IPAF and its modulating effects toward B lymphocytes were investigated. Rapid amplification of cDNA ends (RACE) was conducted to clone the IPAF gene, and the obtained sequence was BLAST compared on the NCBI database. MACS-purified mou...

Herbal medicine has been practiced worldwide in accordance with the recognition of WHO as an essential building block for preliminary healthcare. India, as a rich biodiverse country, has a long history of traditional system of medicine. Orchids, one of the largest diverse angiospermic group of the family Orchidaceae, have occupied a distinct place in human life in terms of their beautiful flowe...

A new lectin was isolated from leaves of the twayblade (Listera ovata). It is a dimeric protein built up of two subunits of M(r) 12,500. This lectin, which is the first to be isolated from a species of the family Orchidaceae, exhibits exclusive specificity towards mannose.

Self-incompatibility (SI) is found in approximately 40% of flowering plant species and at least 100 families. Although orchids belong to the largest angiosperm family, only 10% of orchid species present SI and have gametophytic SI (GSI). Furthermore, a majority (72%) of Dendrobium species, which constitute one of the largest Orchidaceae genera, show SI and have GSI. However, nothing is known ab...

A chemical investigation of the Orchidaceae Arundina gramnifolia has led to the isolation of a novel stilbenoid, named arundinan (1). The structure of 1 has been elucidated as 2-(p-hydroxybenzyl)-3-hydroxy-5-methoxybibenzyl on the basis of physical and chemical evidence and spectral analysis.
