The determination of seven saponins in crude plant extracts by electrospray ionization mass spectrometry (ESI-MS) and fast atom bombardment mass spectrometry (FAB-MS) is described. Distinct protonated and natriated (Na-adduct) molecular ions in ESI-M

Three Pythium isolates [Pythium arrhenomanes isolates (320) & (323)], and Pythium irregulare produced in vitro metabolites that affect normal wheat seedling growth and development. P. arrhenomanes isolates (320 & 323) produced toxic metabolites that

Continuous cropping of mungbean ( Vigna radiata L.) can lead to plant growth inhibition. We have found that allelopathy may be the cause of as much as 10–25% of the inhibition in mungbean plants grown following mungbean plants. Mungbean plants are

Mass spectrometry has been used extensively for saponin determination and structural confirmation. Sapogenins (saponin aglycones) were first studied by Budzikiewicz and coworkers using electron impact (EI) ionization.1 Hostettmann utilized desorption

Saponins are glycosides that commonly occur in higher plants. Saponins are classified into triterpene and steroid groups; the aglycone usually has an oleanane, ursane, or dammarane skeleton. The sugars encountered in saponins are hexoses (including g

Saponins occurring in alfalfa (Medicago sativa L.) are composed of a complicated mixture of triterpenoid glycosides1–3. According to the structure of aglycones, they can be divided into several groups: derivatives of medicagenic acid, oleanolic aci
