Three Apium graveolens (L.) varieties and cultivars within varieties were evaluated for host plant suitability to two polyphagous lepidopteran herbivores: the beet armyworm, Spodoptera exigua (Hiibner), and the cabbage looper, Trichoplusia ni (Hiibner). Overall, there were no significant differences in survivorship, developmental time, and pupal weight of S. exigua or T. ni reared on the two va...

Lily (Lilium) is used as an important edible and medical plant species with a vague taxonomic classification and a long history in China. Bulbs of six Lilium species (L. regale, L. concolor, L. pumilum, L. leucanthum, L. davidii var. unicolor and L. lancifolium) native to China were investigated with a view to their exploitation as a potential source of natural antioxidants due to their phenoli...

OBJECTIVE To examine the in vitro antibacterial activity of the ethanol extract of fresh fruits of Solanum incanum L., fresh leaves of Ricinus communis L. and Allium ampeloprasum var. porrum L., and to determine and quantify the phenol compounds of the investigated plant parts. METHODS This study was carried out at the Faculty of Science, King Khalid University, Abha, Kingdom of Saudi Arabia ...

Kacip Fatimah (Labisia pumila Blume), one of the most famous and widely used herbs, especially in Southeast Asia, is found to have interesting bioactive compounds and displays health promoting properties. In this study, the antioxidant activities of the methanol extracts of leaves, stems and roots of three varieties of L. pumila (var. alata, pumila and lanceolata) were evaluated in an effort to...

Lists are, on the one hand, a useful modeling construct in logic programming because of their not predefined length, on the other hand the concatenation of lists by append(L1,L2,L3) is rather inefficient because it copies the list L1. To avoid the invocation of the append/3-procedure an alternative possibility is the use of incomplete lists of the form [ el1, ... elk | Var], in which Var descri...

0 Cephalotaxine and several of its esters were isolated from Cephalotaxus harringtonia K. Koch var. harringtonia. Although cephalotaxine is inactive, harringtonine, isoharringtonine, homoharringtonine, and deoxyharringtonine have shown significant activity against experimental P388 leukemia and against L-121O leukemia in mice. Keyphrases 0 Cepha/otaxus harringtollia alkaloids-structure. antitum...
