Xanthones from Hypericum japonicum and H. henryi.
A novel N6-substituted adenosine isolated from mi huan jun (Armillaria mellea) as a cerebral-protecting compound.
TLDR
The structure of AMG-1 was proposed as being 6-(5-hydroxy-2-pyridyl-methylamino)-9-beta-ribofuranosylpurine (1) on the basis of its UV, mass, 1H-N MR, and 13C-NMR spectra.

Six compounds were isolated from the seeds of Arctium lappa L. One of them is a new lignan named neoarctin B(VI). The structure has been elucidated on the basis of spectral (UV, IR, 1H-NMR, 13C-NMR,…
[Studies on the chemical constituents of Desmodium styracifolium (Osbeck) Merr].
A new alkaloid, named desmodimine, C12H15NO4, gum, and a new natural product, named desmodilactone, C8H13NO3, mp 84-85 degrees C have been isolated from the aerial parts of Desmodium styracifolium…
Armillaric acid, a new antibiotic produced by Armillaria mellea.
TLDR
A new antibiotic armillaric acid has been isolated from the cultured mycelia of Armillaria mella (Vahl. ex Fr.) Quel (Trichlometaceae) and exhibits inhibitory activity against gram-positive bacteria and yeast.
[Studies on chemical constituents of Veronica lina riifolia Pall. ex Link. sub. dilatata (Nakai et Kitagawa) Hong].
A new flavonoid glycoside, named linariifolioside, C29H32O17 with mp at 232-234 degrees C (dec.), was isolated from the alcohol extract of the dried whole herb of Veronica linariifolia Pall. ex Link…
[Studies on the chemical constituents of Aquilaria sinensis (Lour.) Gilg. V. Isolation and characterization of three 2-(2-phenylethyl) chromone derivatives].
Three 2-(2-phenylethyl) chromone derivatives were isolated from the ethyl acetate soluble fraction of the alcoholic extract of Aquilaria sinensis (Lous.) Gilg. (Thymeleaceae) by silica gel…
[Studies on the chemical constituents of Aquilaria sinensis(Lour.) Gilg. IV. Isolation and characterization of 2-(2-phenylethyl)chromone derivatives].
TLDR
Six chromone derivatives were isolated from the ether soluble fraction of the alcoholic extract of Aquilaria sinensis(Lour.) Gilg. (Thymeleaceae) by silica gel chromatography and one of them was found to be a new chromone, 6-hydroxy-2-[2-(4'-methoxylphenyl)ethyl]chromone(VI).
[Studies on the constituents of Aquilaria sinensis (Lour.) Gilg. I. Isolation and structure elucidation of two new sesquiterpenes, baimuxinic acid and baimuxinal].
