Objective: To develop novel techniques of standardization, this can overlay the method of repid determination of phytoconstituents of Ficus religiosa (F. religiosa) Linn. (Moraceae). From the review of literature it was revealed that no reports were available on standardization parameters of bark of F. religiosa Linn. Method: Phytochemical analysis...

Discoveries in the past two decades have continued to improve our understanding of the pathophysiology of erectile dysfunction disease and animal models have played a significant role to define the basic mechanisms of erectile dysfunction treatment. Both in vitro and in vivo models have been developed in the past years to study the aphrodisiac agen...

Aphrodisiac is the word derived from Aphrodite, the Greek goddess of sexual, love and beauty. An aphrodisiac is defined as an agent (food or drug) that arouses sexual desire. Current sexual dysfunction therapy lack satisfactory success due to adverse effect, hence patients are seeking complementary and alternative medicine to treat sexual dysfuncti...

Objective To develop a novel Standardization technique, which can pave the way for rapid determination of different phytoconstitutents of Ficus racemosa (F. racemosa) Linn. (Moraceae). From extensive literature survey it was revealed that no reports were available on, standardization parameters of fruits of F. racemosa Linn. Methods Phytochemical...

Objective To develop a novel standardization technique, which can pave the way for rapid determination of different phytoconstitutents of Ficus arnottiana (F. arnottiana). Miq. (Moraceae). From extensive literature survey it was revealed that no reports were available on, standardization parameters of F. arnottiana Miq. Methods Phytochemical test,...

In India, indigenous remedies have been used in treatment of sexual dysfunction since the time of Charaka and Sushruta. Plants have been always an exemplary source of drugs and many of the currently available drugs have been derived directly or indirectly from them. An aphrodisiac is defined as an agent that arouses sexual desire. Erectile dysfunct...

This paper presents a review of plants identified from various ethno pharmacological survey with aphrodisiac activity. An aphrodisiac is defined as an agent that arouses sexual desire. Erectile dysfunction or Sexual dysfunction (ED or SD) or male impotence is defined as the inability of a man to achieve and maintain an erection sufficient for mutua...

Objectives: Many diseases are associated with oxidative stress caused by free radicals. The Present research was carried out to evaluate in vitro antioxidant activity potential by five different methods of various extracts of bark of Ficus arnottiana Miq. Methods: Antioxidant activity was determined by using five different in vitro assay including...

Sexual dysfunction (SD) or male impotence is defined as the inability to have or sustain an erection long enough to have a meaningful sexual intercourse. SD tends to occur gradually until the night time or early morning erections cease altogether or are so flaccid that successful intercourse does not occur. Sexual health is an important determinant...

Sexual activity has been universally recognized as a vital component of a normal and healthy lifestyle and general well-being. Sexual dysfunction especially erectile dysfunction is a serious public health problem as reflected in epidemiological data. Aphrodisiac is the word derived from Aphrodite, the Greek goddess of sexual, love and beauty. An ap...

Rotationally inelastic collisions of N2B3Pig with argon have been investigated by optical-optical double resonance. Specific B state rotational levels are prepared by pulsed pump laser excitation of metastable N2(A) molecules, which have been prepared in a flow system, on isolated rotational lines in the B-A (3,0) band near 688 nm. A probe laser in...

Laser fluorescence excitation spectra and transition wavenumbers are reported for the overlapping B-A (8, 7) and B-X (8, 11) bands of the CN molecule. The intensities of rotational lines in these bands depend on the relative magnitude and phase of the B-A and B-X transition moments because the lower levels can have significant A and X state charact...

An optical–optical double resonance experiment has been carried out to study rotationally inelastic collisions of N2 B 3Πg v=3 by argon with initial and final state resolution. Nitrogen molecules in the metastable A state are generated by collisional excitation transfer from metastable argon atoms in a flow system. Specific B state rotational level...

An optical–optical double resonance technique has been employed for the study of collisional transfer from the CN A 2Π v=8 manifold to X 2Σ+ v=12 with initial and final rotational state resolution. In contrast to our previous studies of vA=3 to vX=7 and vA=7 to vX=11 collisions, no significant even–odd oscillation in the final X state rotational po...

Photolytic production of CN molecules in a flow of metastable argon and cyanogen is reported. At the maximum pump laser fluence investigated (0.4 J/cm2), ground-state CN concentration is found to be enhanced by about 1% over the ambient CN produced by collisional dissociation of C2N2 by Ar*. It is concluded that this signal is due to photodissociat...

CN B-X emission has been observed upon pulsed laser excitation of the A 2Π v = 10 vibrational manifold, which is nearly isoenergetic with B 2Σ+v = 0. Because of the B-A perturbation, a number of vA = 10 rotational levels have significant B state character. For short observation intervals, the B-X emission is excited most strongly when such perturbe...

Collisional transfer within the CN A 2Π v=3 vibrational manifold and to the X 2Σ+ v=7 manifold has been studied with initial and final rotational state resolution by an optical–optical double resonance technique. Despite the large energy gap between these two manifolds, the interelectronic cross sections are significant for only a relatively small...

Collisional transfer from the A 2Π state of CN has been studied with initial and final state resolution by an optical–optical double resonance technique. Specific rotational levels in the v=7 vibrational manifold of the A state of CN in a flow of several Torr of argon are prepared by pulsed laser excitation in the A–X (7,2) band. After a short time...

An optical-optical double resonance technique has been used to study transfer between specific quantum levels in the A2Π and X2Σ2 states of the CN radical in collisions with argon. Specific rotational levels within the v = 7 A state vibrational level are prepared by laser excitation in the A-X (7,2) band, while collisionally populated levels in thi...
