Phenolic compounds from Origanum vulgare and their antioxidant and antiviral activities.
In the present study, six new phenolic compounds (1-6) along with five known ones were isolated from the ethanol extract of the whole plants of Origanum vulgare. The structures of the new compoundsExpand
Clerodane diterpenoids from Croton crassifolius.
Seven new clerodane diterpenoids (1-7) were isolated from roots of Croton crassifolius, along with six known compounds. The structures were elucidated by extensive spectroscopic methods (IR, UV,Expand
Cytotoxic and anti-inflammatory active phloroglucinol derivatives from Rhodomyrtus tomentosa.
Seven undescribed phloroglucinol derivatives, tomentodiones N-T, and eleven known ones were isolated from Rhodomyrtus tomentosa. Tomentodione N is the first example of a β-triketone unit coupled withExpand
Grandiflodines A and B, two novel diterpenoid alkaloids from Delphinium grandiflorum
Two novel diterpenoid alkaloids, grandiflodines A and B (1 and 2), were isolated from Delphinium grandiflorum. Compound 1 represents a rare hetisine-type C20-diterpenoid alkaloid in which the bondExpand
Dimeric Matrine-Type Alkaloids from the Roots of Sophora flavescens and Their Anti-Hepatitis B Virus Activities.
Six unusual matrine-type alkaloid dimers, flavesines A-F (1-6, respectively), together with three proposed biosynthetic intermediates (7-9) were isolated from the roots of Sophora flavescens.Expand
Potent anti-angiogenic component in Croton crassifolius and its mechanism of action.
ETHNOPHARMACOLOGICAL RELEVANCE The root of Croton crassifolius Geisel is traditionally used in China for the treatment of snake bites, stomach ache, sternalgia, joint pain, pharyngitis, jaundice andExpand
New steroidal saponins and sterol glycosides from Paris polyphylla var. yunnanensis.
Four new steroidal saponins, pariposides A-D (1-4), and two new sterol glycosides, pariposides E-F (5-6), along with eight known steroidal saponins (7-14), two known sterol glycosides (15-16), andExpand
Ciliatonoids A and B, Two Limonoids from Toona ciliata.
Three new ring B-seco limonoids, ciliatonoids A-C (1-3), were isolated from Toona ciliate and structurally characterized by spectroscopic data, X-ray crystallography, and electronic circularExpand
Eudesmane-type sesquiterpene derivatives from Laggera alata.
Ten eudesmane-type sesquiterpene derivatives (1-10), including six cuauhtemone derivatives (1-6), one di-norsesquiterpene (3-oxo-di-nor-eudesma-4-en-11-oic acid, 7), and three eudesmane glycosidesExpand
