The results suggest that the adjuvant activity of saponins does not relate with haemolytic activity, and it is considered that not only the functional groups themselves, but the overall conformation harmoniously consisting of such functional groups, affects adjUvant activity.

Polyphenolic compounds may be involved in the antiobesity effects of SRHW in rats through inhibition of fat metabolizing enzymes (PL, LPL and GPDH) and enhanced lipolysis and inhibited hormone-sensitive lipase activity in rat adipose tissue.

Results indicate that insulin-releasing action of gymnemic acid IV may contribute to the antihyperglycemic effect by the leaves of G. sylvestre, which may be an anti-obese and anti hyperglycemic pro-drug.
