Reserpine, the purified alkaloid of Rauwolfia serpentina, was the first potent drug widely used in the long-term treatment of hypertension. Rauwolfia serpentina is a tropical woody plant of the Apocyanaceae family ingenious to Asia, South America and Africa. Extracts of its different parts and of plants resembling to rauwolfia were used in Hindu medicine for snakebite, insomnia, insanity and many other diseases and complaints. In Europe, Georg Eberhard Rumpf first reported about rauwolfia in his Herbarium amboinense, 1755. The first modern paper about therapeutic applications of the whole root of rauwolfia was published in 1931 in the Indian Medical Journal by Sen and Bose, and many papers dealing with botanics, chemistry and pharmacology then appeared in Indian and European periodics. In 1949, Vakil published the first report of the antihypertensive effect of rauwolfia in the British Heart Journal. In the Ciba laboratories in Basel, Switzerland, Mueller, Schlittler and Bein analysed various rauwolfia alkaloids and published in 1952 the first complete report about their chemistry and pharmacology. In the same year, reserpine was introduced under the name Serpasil in the treatment of hypertension, tachycardia and thyreotoxicosis. The combination of reserpine, dihydroergocristine and a diuretic is still on the market (Brinerdin, Crystepin). In psychiatry, reserpine was prescribed as a tranqulizing agent until modem synthetic antidepressant and antipsychotic drugs were introduced. The author also briefly summarizes the chemistry, pharmacology and clinical use of reserpine.

Sarpagandha ghanvati is a classical Ayurvedic formulation widely prescribed for anxiety and insomnia. It contains Sarpagandha (roots of Rauwolfia serpentina L. (Benth.) Ex Kurz; Family: Apocyanaceae), Khurasani ajowan (Hyocyamus niger L.; Family: Solanaceae) seeds, Jatamansi (Nardostachys jatamansi DC. Family: Valerianaceae) roots and Pipplamul (root of Piper longum L.; Family: Piperaceae). The objective of this study was to make a comparative evaluation of Ghanvatis and tablets of this formulation. Two tablet formulations were prepared; one incorporating only powders of all ingredients; the other with ethanol extracts of the first three ingredients and powder of Piper longum root. Similarly, two types of Sarpagandha ghanvati pills were prepared; one as per Ayurvedic Formulary of India; the other with ethanol extracts of the first three ingredients and powder of Piper longum root. Alcohol extracted 0.22% w/w of total alkaloids as against 0.061% w/w extracted by water. Tablets prepared with powders of all the ingredients had friability more than 3.0% where as those prepared with ethanol extract had very low friability. Ghanvatis, prepared as per the Ayurvedic formulary, did not show reserpine although other alkaloids were present. They showed less content uniformity and lower drug release. Ethanol extracted reserpine along with other alkaloids. Ghanvatis made with the alcoholic extracts exhibited better content uniformity and drug release than the traditional formulation. Tablets prepared with powders or extracts of the ingredients exhibited good content uniformity but the release of alkaloids from the tablets of powders was only 80%. Tablets of the extracts had good content uniformity with 90% release of the total alkaloids. Tablets prepared with alcoholic extracts using 1% polyvinylpyrrolidone as binder and 5% dried starch powder as disintegrating agent confirmed to all the requirements. Thus, the study shows tablets made with the extracts are superior to Ghanvatis and powder tablets.
