A New Triterpenoid Saponin from the Stem Bark of Pometia pinnata

“…Fast atom bombardment spectra (FAB-MS) was recorded on a double focusing Varian MAT-312 spectrometer. 1 H and 13 C NMR, COSY, HMQC, HMBC spectra were measured on AM-500 and 300 Bruker spectrometers. Acid Hydrolysis: Compound 1 (10 mg) was refluxed with 10 mL HCl (20%) in aq.…”

Antioxidant Activity of the Extracts Derived from Terminalia catappa

“…Terminalia catappa is very well known for its therapeutic values since long and has proved by many researchers to be useful as anti-inflammatory (Fan et al, 2004;Jayasinghe et al, 2000), anticancer (Kandil et al, 1999), antihepatotoxic (Lin et al, 2001), antigenotoxic (Chen et al, 2000), anticlastogenic (Liu et al, 1996) and for the treatment of skin aging, irritation, hyperpigmentation, allergy (Renimel et al, 1998) and bronchial asthama in children (Prazeres, 1995). The plant also exhibits antimicrobial (Pawar and Pal, 2002), insecticidal and molluscicidal activities (Jayasinghe et al, 2000).…”
