A pentacyclic triterpene that occurs widely in many PLANTS as the free acid or the aglycone for many SAPONINS. It is biosynthesized from lupane. It can rearrange to the isomer, ursolic acid, or be oxidized to taraxasterol and amyrin.
A plant genus of the family CELASTRACEAE.
Flammable, amorphous, vegetable products of secretion or disintegration, usually formed in special cavities of plants. They are generally insoluble in water and soluble in alcohol, carbon tetrachloride, ether, or volatile oils. They are fusible and have a conchoidal fracture. They are the oxidation or polymerization products of the terpenes, and are mixtures of aromatic acids and esters. Most are soft and sticky, but harden after exposure to cold. (From Grant & Hackh's Chemical Dictionary, 5th ed & Dorland, 28th ed)
A plant genus of the family RHAMNACEAE. Members contain nummularogenin (a spirostane) and is the source of an edible fruit.
A plant genus of the family SAPOTACEAE. Members contain triterpenoid saponins. Latex from bark incisions is processed into gutta balata.
A plant genus of the family ALISMATACEAE. The flowers have 3 green sepals, 3 yellow and white petals, 6 stamens, and several pistils. Members contain TRITERPENES and SESQUITERPENES. Alisma is a component of tokishakuyakusan. Some species in this genus are called water plantain which is also a common name for other ALISMATACEAE plants.
A plant genus of the family Lecythidaceae. Members contain nasimalun A and B (neo-clerodane diterpenoids).
A plant genus of the family RUBIACEAE. Members contain genepin, from which geniposide is obtained for use as a crosslinking agent in ADHESIVES, and 3-caffeoyl-4-sinapoylquinic acid.
The showy mistletoe plant family of the order Santalales, subclass Rosidae, class Magnoliopsida. This includes parasitic tropical plants with haustoria connecting to the hosts. The leaves are opposite and thick. The flowers (4-7) have both calyx and corolla. The fruit is a berry with one seed.
The saxifrage plant family of the order ROSALES, subclass Rosidae, class Magnoliopsida. The leaves are alternate and sometimes deeply lobed or form rosettes. The flowers have both male and female parts and 4 or 5 sepals and petals; they are usually in branched clusters. The fruit is a capsule with many seeds.
A family of bracket fungi, order POLYPORALES, living in decaying plant matter and timber.
A plant species of the family CUCURBITACEAE. It is a source of ribosome-inactivating proteins and triterpene glycosides.
Magnetic Resonance Spectroscopy
Polyphenolic compounds with molecular weights of around 500-3000 daltons and containing enough hydroxyl groups (1-2 per 100 MW) for effective cross linking of other compounds (ASTRINGENTS). The two main types are HYDROLYZABLE TANNINS and CONDENSED TANNINS. Historically, the term has applied to many compounds and plant extracts able to render skin COLLAGEN impervious to degradation. The word tannin derives from the Celtic word for OAK TREE which was used for leather processing.
An order of fungi in the phylum BASIDIOMYCOTA having macroscopic basidiocarps. The members are characterized by their saprophytic activities as decomposers, particularly in the degradation of CELLULOSE and LIGNIN. A large number of species in the order have been used medicinally. (From Alexopoulos, Introductory Mycology, 4th ed, pp504-68)
A plant genus of the family EBENACEAE, order Ebenales, subclass Dilleniidae, class Magnoliopsida best known for the edible fruit and the antibacterial activity and compounds of the wood.
Any compound that contains a constituent sugar, in which the hydroxyl group attached to the first carbon is substituted by an alcoholic, phenolic, or other group. They are named specifically for the sugar contained, such as glucoside (glucose), pentoside (pentose), fructoside (fructose), etc. Upon hydrolysis, a sugar and nonsugar component (aglycone) are formed. (From Dorland, 28th ed; From Miall's Dictionary of Chemistry, 5th ed)
Inhibitory Concentration 50
Antineoplastic Agents, Phytogenic
Alteration of the immune system or of an immune response by agents that activate or suppress its function. This can include IMMUNIZATION or administration of immunomodulatory drugs. Immunomodulation can also encompass non-therapeutic alteration of the immune system effected by endogenous or exogenous substances.
