Chemical and Chemotaxonomical Studies of Filices. LXIX. The Novel Coumarins of Macrothelypteris torresiana CHING var. calvata HOLTT. (=M.oligophlebia CHING)

Antioxidative and Antihyaluronidase Activities of Some Contituents from the Aerial Part of Daucus carota.

“…Structure elucidation of 1-5 Compounds 1-5 were identified as luteolin 7-O-␤-glucopyranoside (Harborne & Mabry, 1982;Harborne, 1994), chrysoeriol 7-O-␤-glucopyranoside (Harborne & Mabry, 1982;Harborne, 1994;Tomás et al, 1986), chlorogenic acid (Nishizawa et al, 1988), maltol 3-O-␤-glucopyranoside (Hori et al, 1987) and benzyl ␤-glucopyranoside (Miyase et al, 1987), respectively, on the bases of spectral data (Fig. 1).…”

Nephroprotective activity ofMacrothelypteris oligophlebiarhizomes ethanol extract

“…Its rhizomes have been used as a folk medicine mainly for the treatment of diseases such as edema, boils, burns, and roundworms (Editorial Board of China Herba, 1998). Study on the chemical constituents of this species has been conducted previously and several flavonoids were isolated, including kaempferol, rutin and kaempferol-3-O-β-rutinoside (Hori et al, 1987). However, reports on the pharmacological effects of M. oligophlebia have not been documented.…”

Occurrence, Structure and Taxonomic Implications of Fern Constituents

“…Odontoside (66) is a glucoside ester in Odontosoria gymnogrammoides, in which the benzylic alcohol of 3,4-dihydroxybenzylalcohol 3-0-P-D-glucoside is esterfied with protocatechuic acid (51). Sugar esters (75)(76)(77)(78)(79)(80)(81)(82)(83)(84) are very common plant constituents, but in ferns only fifteen are known and eight of them (80)(81)(82)(83)(84)(85)(86)(87) are sulphate esters ofhydroxycinnamic acid-sugar derivatives. Several caffeic acid esters of hydroxy acids (90,91,92,93) are known in ferns.…”

“…From Asplenium wilfordii asplenoside (114) which is a tetrahydronaphtalene glycoside has been isolated (55). (86) have been isolated from ferns. However, the biosynthetic pathways leading to these compounds are not known.…”

“…Maltol (829) and hydroxymaltol glycosides (830, 831, 832) have been detected in several species of the Thelypteridaceae and others (55,86,210,256,264).…”
