Phylogenetic, population structure, and population demographic analyses reveal that Vicia sepium in Japan is native and not introduced.

Vicia sepium (bush vetch) is a perennial legume widely distributed throughout the Eurasian continent. However, its distribution in Japan is limited to Mt. Ibuki and small parts of central and southern Hokkaido.

Identification of Anogeissus latifolia Wallich and analysis of refined gum ghatti.

Natural medicinal exudates such as gum arabic are high-molecular-weight natural polysaccharides and are highly soluble in water. The dissolved solutions of these exudates show viscous behavior and exhibit favorable emulsion stability. These exudates have been widely used not only as a medicinal additive, such as a coating agent for tablets and as an emulsifier and stabilizer in beverage and food products, but also for other industrial applications, such as paints and ink.

The structure of a new crystalline cevane alkaloid: its identity with persicanidine B and harepermine.

The structure of a new crystalline base (melting point (mp) 167-169 degrees C) obtained from Fritillaria imperialis was elucidated as (20R, 25R)-5alpha,17beta-cevanine-3beta,6beta-diol, X-ray diffraction analysis of the mono-hydrate. The base was found to be identical with persicanidine B and also with harepermine.
