[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
Bisbenzylisoquinoline alkaloids from Stephania cepharantha and their effects on proliferation of cultured cells from the murine hair apparatus.
TLDR
Cepharanthine, cepharanoline, isotetrandrine, and berbamine showed significant activities in the range of 0.01-0.1 microgram/ml, but had no activity on cultured keratinocytes or fibroblasts from the murine skin.
[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).
Isolation and structures of two new sesquiterpenoid aromatic esters: armillarigin and armillarikin1.
TLDR
Two new sesquiterpenoid aromatic esters are isolated from the mycelial extract of ARMILLARIA MELLEA (Vahl.ex Fr.) Quel.
Two Novel Protoilludane Norsesquiterpenoid Esters, Armillasin and Armillatin, from Armillaria mellea.
Two novel protoilludane norsesquiterpenoid esters, named armillasin and armillatin, have been isolated from the artificially cultured mycelium of ARMILLARIA MELLEA (Tricholomataceae). Their
[Chemical constituents of Armillaria mellea mycelium. VI. Isolation and structure of armillaripin].
TLDR
A new protoilludane sesquiterpenoid aromatic ester was isolated from the petroleum ether extract of the artificially cultured mycelium of Armillaria mellea by silica gel chromatography and its structure was deduced as I and confirmed by single-crystal X-ray analysis.
[Triterpene constituents from Euphorbia nematocypha Hand-Mazz].
Seven triterpenoids have been isolated from the roots of Euphorbia nematocypha Hand-Mazz. through chromatography on 20% AgNO3-silica gel. One of them was identified as a new compound named
