“…The proved that the reduction in growth of the larvae was not entirely due to antifeedent, but partly due to the toxic effects of the aglaroxin A compound. Qi et al (2003) have been identified compound munroniamide from Munronia henryi and that has proved antifeedent activity against Pieris brassicae L.…”

This review described the physiological and biochemical effects of various secondary metabolites from Meliaceae against major Lepidopteran insect pest including, Noctuidae and Pyralidae. The biochemical effect of major Meliaceae secondary metabolites were discussed more in this review. Several enzymes based on food materials have critical roles in nutritional indices (food utilization) of the insect pest population. Several research work has been referred and the effect of Meliaceae secondary metabolites on feeding parameters of insects by demonstrating food consumption, approximate digestibility of consumed food, efficiency of converting the ingested food to body substance, efficiency of converting digested food to body substance and consumption index was reviewed in detail. Further how the digestive enzymes including a-Amylases, α and β-glucosidases (EC 3.2.1.1), lipases (EC 3.1.1) Proteases, serine, cysteine, and aspartic proteinases affected by the Meliaceae secondary metabolites was reviewed. Further effect of Meliaceae secondary metabolites on detoxifying enzymes have been found to react against botanical insecticides including general esterases (EST), glutathione S-transferase (GST) and phosphatases was reviewed. Alkaline phosphatase (ALP, E.C.3.1.3.1) and acid phosphatase (ACP, E.C.3.1.3.2) are hydrolytic enzymes, which hydrolyze phosphomonoesters under alkaline or acid conditions, respectively. These enzymes were affected by the secondary metabolites treatment. The detailed mechanism of action was further explained in this review. Acethylcholine esterase (AChE) is a key enzyme that terminates nerve impulses by catalyzing the hydrolysis of neurotransmitter, acetylcholine, in the nervous system of various organisms. How the AChE activity was altered by the Meliaceae secondary metabolites reviewed in detail.

“…The antifeedant properties of limonoids from Melia azederach (chinaberry), and related plants, have been reviewed (Nakatani 1999). Other tetranortriterpenes such as nymania-3 from Dysoxylum malabaricum (Govindachari et al 1999), hirtin derivatives from Trichilia palida (Simmonds et al 2001), munroniamide from Munronya henryi (Qi et al 2003) and xyloccensins A-K and xylogranatins A-R from species of the Xylocarpus genus (Wu et al 2008;Shen et al 2009) act as feeding deterrents. Triterpenes of this type from the Meliaceae and Rutaceae groups have been tested showing that the orientation of the furan group and the hydroxylation of specific carbons affect their antifeedant properties against the fall armyworm (Spodoptera litura; Suresh et al 2002).…”

Pentacyclic triterpenes are abundant in the plant kingdom and have a wide array of pharmacological activities. They also have insect antifeedant effects and therefore apparently play a role in plant defense. In this paper, we describe the insecticidal activity of pentacyclic triterpenes of plant origin from different chemical classes on several insect pests (Spodoptera littoralis, Leptinotarsa decemlineata and Myzus persicae), their phytotoxic properties and their selective cytotoxic effects on insect-derived Sf9 and mammalian CHO cells. We also discuss the role they play in plant defense based on these activities.

“…1 Up to now, some phytochemical studies have been reported on M. delavayi [2][3][4][5] and M. henryi [6][7][8][9] , and tetranortriterpenoids and triterpenoids are their main components. Especially, tetranortriterpenoids exhibit chemical defensive function in nature, such as antibacterium, antifungal, 2 and antifeeding 8 activities.…”

Abstract:Two new minor constituents, musinisins A (1) and B (2), together with five known compounds (3-7), were isolated from the aerial parts of Munronia sinica. Their structures were established by means of spectroscopic methods and the absolute stereochemistry of 1 was determined by single crystal X-ray experiment. Compound 4 showed antiangiogenic activity evaluated by a zebrafish model and apoptosis-inducing effect on A549 lung cancer cells.
