ABSTRACT The effect of reserpine on the secretion of FSH and LH was studied as well as the role of the peripheral effect of reserpine after hypophysectomy. The results in the unoperated animals suggest that reserpine inhibits the pituitary secretion of both FSH and LH. Both these hormones combined with reserpine had a very different biological effect than was seen without reserpine. HCG (LH-like) and particularly PMS (FSH-like) hormones combined with reserpine caused definite enlargement of the ovaries. In the hypophysectomized groups, the effect of the PMS and HCG hormones administered together with reserpine or without it was the same with regard to the weight of the ovaries, but not with regard to their histological picture. On the basis of these results, reserpine may be said to have a peripheral effect although the nature of its mechanism of action is difficult to state. Reserpine probably affects the ovaries by inhibiting the follicular cycle and, consequently, the formation of new and more mature follicles.

Flavonoids are naturally occurring plant polyphenols found universally in all fruits, vegetables and medicinal plants. They have emerged as a promising candidate in the formulation of treatment strategies for various neurodegenerative disorders. The use of flavonoid rich plant extracts and food in dietary supplementation have shown favourable outcomes. The present review describes the types, properties and metabolism of flavonoids. Neuroprotective role of various flavonoids and the possible mechanism of action in the brain against the neurodegeneration have been described in detail with special emphasis on the tangeritin.
