aesculus turbinata/protease

Eight bioactive triterpenoid saponins (1-8) were isolated from the seeds of Aesculus chinensis, four of which are novel compounds. The major saponins were identified as escin Ia (1), Ib (2), isoescin Ia (3) and Ib (4), while the new compounds were identified as

In the present study we describe the effect of chloronicotinoid pesticide (imidacloprid) on the digestive enzymes activity of the Cameraria ohridella larvae after lasting 1 year sublethal exposure to imidacloprid pesticide. Caterpillars - L4 stage (fourth instar, hyperphagic tissue-feeding phase) -

This article presents the activity of carbohydratases and proteases in the midgut of Cameraria ohridella larvae--an oligophagous pest whose preferred feeding is horse chestnuts leaves. Optimal media pH of the assayed enzymes were similar to those of other Lepidopterans. Relatively high amylase

Triterpene and steroid saponins and sapogenins of medicinal plants (Aesculus hippocastanum L., Hedera helix L., Ruscus aculeatus L.) are claimed to be effective for the treatment/prevention of venous insufficiency. In this work we evaluated the inhibitory effects of these plant constituents on the
