Breast cancer affects millions of women annually worldwide and is the leading cause of cancer death in women. Various bioactive phytochemicals based on natural products are considered to be an important source of chemopreventive agents. In this study we report-to our knowledge for the first time-9

Phytochemical investigation on rhizomes of Kaempferia angustifolia has afforded a new abietene diterpene, kaempfolienol (1) along with crotepoxide (2), boesenboxide (3), 2'-hydroxy-4,4',6'-trimethoxychalcone (4), zeylenol (5), 6-methylzeylenol (6), (24S)-24-methyl-5α-lanosta-9(11), 25-dien-3β-ol

Novel alkylphenols, ardisiphenols A-C (1-3) and a novel bergenin derivative, demethoxybergenin (10) were isolated from the fruits of Ardisia colorata (Myrsinaceae), together with known alkylresorcinols (4-6), embelin (7), myricetin (8), quercetin (9), bergenin (11), norbergenin (12), kaempferol

BACKGROUND Paris quadrifolia L. is a medicinal plant which contains steroidal saponins. The present study reports isolation and structural identification of six pennogenyl saponins obtained from P. quadrifolia rhizomes. The four spirostan saponins were obtained from P. quadrifolia for the first

Bioactivity-guided fractionation of cranberries was used to determine the chemical identity of bioactive constituents. Twenty compounds were isolated using gradient solvent fractionation, silica gel and ODS columns, and preparative RP-HPLC. Their chemical structures were identified using HR-MS, 1D

The increasing rate of cancer incidence has encouraged the search for novel natural sources of anticancer compounds. The presence of small quantities of taxol and taxanes in Corylus avellana L. has impelled new potential applications for this plant in the field of biomedicine. In the present work,

Bioactivity-guided fractionation of Red Delicious apple peels was used to determine the chemical identity of bioactive constituents, which showed potent antiproliferative and antioxidant activities. Twenty-nine compounds, including triterpenoids, flavonoids, organic acids and plant sterols, were

Dillenia suffruticosa, which is locally known as Simpoh air, has been traditionally used to treat cancerous growth. The ethyl acetate extract of D. suffruticosa (EADs) has been shown to induce apoptosis in MCF-7 breast cancer cells in our previous study. The present study aimed to elucidate the

Rhaponticin (RA; 3'5-dihydroxy-4'-methoxystilbene 3-O-β-D‑glucopyranoside) is a component isolated from various medicinal herbs including Rheum undulatum L. RA has been reported to be an effective treatment for allergy, diabetes, thrombosis, liver steatosis, lung fibrosis and colitis. In addition,
