Background: Unani System of Medicine (USM) has its origin to Greece. To ensure and develop the quality, authenticity of Unani drugs, standardization on modern analytical parameter is essential requirement for drugs. Objectives: The aimed of the present study was to develop a standard profile of "Qurṣ-e-Mafasil" by systematic study through authenticated ingredients, pharmacognostic identification followed by physicochemical, TLC, HPTLC fingerprinting analysis as per standard protocol. Material and Methods: In this study three batches of "Qurṣ-e-Mafasil" QM were prepared by standard method as per UPI had been followed by organoleptic properties of formulation such as appearance, color, odor, taste. Powder Microscopy and physicochemical studies were carried out such as Uniformity of weight, Friability, Disintegration time, hardness, LOD, ash vales and extractive values in like aqueous, alcohol & hexane. Further qualitative tests such as Thin-Layer Chromatography (TLC), and High-Performance Thin Layer Chromatography (HPTLC) studies were also carried out to develop fingerprint pattern of the alcoholic solvent extract of QM. Phytochemical screening was carried out in different solvent extracts such as alcoholic, aqueous and chloroform extracts to detect the presence phytoconstituents in the formulation QM. Heavy metals, Microbial Load Contamination and pesticidal residues were also determined. Results: Qurṣ-e-Mafasil showed tablet-like appearance, light brown colour, mild pungent odour and acrid taste. Uniformity of weight (mg), friability (rpm), and hardness (kg/cm) and disintegration time was ranged between (500 to 503), (0.0340 to 0.038), (8.40 to 8.67) and (4-5 minutes) respectively for the three batches. Loss in weight on drying at 105℃ was ranged between (8.3425 to 8.7346). Extracted values were calculated in distilled water ranged between (30.9091 to 31.4358), hexane (1.1419 to 1.4281), and alcohol (3.3352 to 3.3962).

Objectives: This study aimed to investigate the stability of a decoction using three herbal plants and their major components according to the storage conditions and periods. Materials and Methods: A three-herb mixture (1:1:1) of Glycyrrhiza uralensis Fischer, Artemisia capillaris Thunberg, and Poncirus trifoliata Rafinesqui was decocted and kept at room temperature ($25{\pm}2^{\circ}C$) or cold temperature ($4^{\circ}C$) for 0, 2, 4 or 8 weeks in liquid form in a plastic pack under dark conditions. At time points given, they were lyophilized. 200 mg of powdered samples were dissolved in 1 mL of 90% methanol and then applied to a high performance thin layer chromatography (HPTLC) with glycyrrhizin, 6,7-dimethoxycoumarin or poncirin for quantitative or qualitative analysis. Results: There were no gross changes in HPTLC-based compositional band-patterns of the three herbal mixture according to the storage conditions and period. The major components of each herb, glycyrrhizin, 6,7-dimethoxycoumarin and poncirin, showed slight time-dependent reduction in their contents both at room and cold temperature for 8 weeks. Conclusion: We could conclude that the current herbal decoction is generally safe for the stability at both RT or CT for at least 8 weeks. Nevertheless, we proposed that further advanced studies are required for more multiple herbal mixtures and longer storage periods.

Objectives : Schisandrae Fructus (SF) has traditionally been used to balance level of body fluid and to strengthen kidney function. It has been reported that the SF extract has antioxidant, hepatoprotective, neuroprotective and anticancer effects. This study investigated an antiproliferative effect of SF extract on PC-3 human prostate cancer cells and analyzed active ingredients of SF extract qualitatively and quantitatively. Methods : We examined the antiproliferative effect of SF extract with MTT assay, DAPI staining and annexin-V/7-AAD double staining. The active ingredients of SF extract were identified by using HPTLC and HPLC/DAD system. Results : SF-chloroform fraction inhibited growth of PC-3 cells and changed the morphology of nucleus in a dose dependent manner. A dose-dependent apoptotic cell death was also measured by flow cytometry analysis. It was analyzed that SF-chloroform fraction contained more schizandrin than other fractions by using HPTLC and HPLC/DAD system. Conclusions : These results suggest that SF extract and schizandrin may be a potential chemotherapeutic agent for the control of PC-3 human prostate cancer cells.

Neuronal damage subsequent to transient cerebral ischemia is a multifactorial process involving several overlapping mechanisms. Gangliosides, sialic acid-conjugated glycosphingolipids, reduce the severity of acute brain damage in vitro. However their in vivo effects on the cerebral cortex damaged by ischemic infarct are unknown. To assess the possible protective role of gangliosides we examined their expression in the cerebral cortex damaged by ischemic infarct in the rat. Ischemia was induced by middle cerebral artery (MCA) occlusion, and the resulting damage was observed by staining with 2, 3, 5-triphenylterazolium chloride (TTC). High-performance thin-layer chromatography (HPTLC) showed that gangliosides GM3 and GM1 increased in the damaged cerebral cortex, and immunofluorescence microscopy also revealed a significant change in expression of GM1. In addition, in situ hybridization demonstrated an increase in the mRNA for ganglioside GM3 synthase. These results suggest that gangliosides GM1 and GM3 may be synthesized in vivo to protect the cerebral cortex from ischemic damage.

Magnolol and honokiol, the main components of Magnoliae Cortex, were isolated and used as the standard substances for the analysis. In order to determine the contents of magnolol and honokiol in Magnoliae Cortex originated from Korea, China and Japan, both HPLC and HPTLC methods are applied and compared with each other. The components were separated on C8 column with acetonitrile-water-acetic acid (50:50:1) in HPLC and detected at UV 294nm. The components separated on HPTLC precoated silica gel plate with chloroform-methanol (9:1) were detected directly on the plate at 254nm. The contents of magnolol and honokiol in Magnoliae Cortex were in the wide range of 0.01~2.8% and 0.005~0.8%, respectively, according to their purchase places. It is also applicable to the quality control of various preparation from Magnoliae Cortex.

The rapid and sensitive determination method of sildenafil and its related compounds (Vardenafil, Homosildenafil, Tadanafil.) has been investigated using high performance thin layer choromatography (HPTLC). Optimizing separation conditions and simultaneous determination method of these compounds were studied. The calibration curves of those compounds at 254 nm was found to be linear in the range of $1.0{\sim}56.5{\mu}g/mL$, respectively. The detection limts (LOD) and quantification limits (LOQ) of these were found to be $0.8{\sim}1.8{\mu}g/mL$ and $1.0{\sim}2.3{\mu}g/mL$. The coefficient of variation (C.V.) were less than 2.5%. Finally, the present method was applied to determine sildenafil and its related substances in dietary supplement.

Extraction methods and instrumental analytical conditions were compared to establish a fast and appropriate analytical method to determine saikosaponins in Bupleurum falcatum. Using HPLC, analysis of diene-saikosaponin treated with 2% acid was faster than that of saikosaponin itself. Among various extraction methods, extraction by standing in methanol at room temperature showed highest efficieny, and extraction with boiling methanol was shorter in analytical time and showed good chromatogram. And we could analyze many samples faster using HPTLC but the analytical accuracy was low. In extraction and analysis of saikosaponins, extraction with boiling methanol and acidic treatment was fast and easy analytical method. And for selecting useful lines in component breeding, we think TLC method was better.

In the cosmetics field, facial skins have been classified into four types according to self estimation as well as physiological parameters. The aim of this study is to understand skin condition in the levels and composition of stratum corneum (SC) lipids, and to propose new classification for skin types. We assessed the relationship between the SC lipid composition and the self-estimated skin types or physiological parameters of the skin. Sensitive skin has been of great concern over the last decades, and it should be recognized as a skin type. Therefore, we also investigated the influence of the SC lipid composition on variations of sensitivity evaluated by the Stinging Test. Fifty-five healthy Japanese women aged 22-44 participated in this study. Skin biopsies were taken from facial skin using polyethylene sheet with cyanoacrylate. SC lipids were extracted and separated into individual lipid classes. The combined ceramides and cholesterol were quantified by HPTLC. Free fatty acid was quantified according to the ACS-ACOD method. Instrumental measurements were made at the site around the biopsy. In addition, the Stinging Test and a sensory evaluation questionnaire were administered to all subjects. The generally recognized O-D skin type classification is dependent on the consumer`s subjective assessment with respect to their skin troubles. The product of hydration state and skin surface lipid level showed a significant correlation with self-estimated skin types. The oily-dry skin type classified according to physiological parameters as well as SC lipid levels should be characterized as delicate skin with its barrier function deteriorating in the winter. Two groups of sensitive skin were established. One is the barrier function of the skin is deteriorated, and another is the sebaceous gland activity is in decline.

Saussurea costus (Falc.) Lipchitz syn S. lappa C. B. Clarke (commonly known as 'Kuth') belonging to the family Asteraceae is a well known medicinal plant which finds wide usage in different indigenous systems of medicine of India, China, Korea & Tibet. In different folk medicines the roots of S. costus are used to treat various disorders like ulcer, stomachache, malaria, leprosy, dysentery and toothache. However due to over exploitation, it has become endangered and has become the concern of different governmental bodies in India. The increasing demand of this endangered Himalayan species has resulted in a situation where it is often substituted, knowingly or unknowingly, by other morphologically similar species. Arctium lappa, belonging to the same family, is one such plant that has often been found to be present in the market samples of 'Kuth'. The present study was thus carried out and morphoanatomical characters, physicochemical as well as chemical parameters were developed for proper identification of roots of S. costus and its differenciation from A. lappa as well as authentication of the commercial market samples. The detailed morphoanatomical studies revealed that roots of S. costus can be distinguished from A. lappa on the basis of some important microscopial characters eg. the schizogenous resin ducts observed in roots of S. costus, were absent in A. lappa.. Besides, the HPTLC fingerprint profile showed a distinct band at Rf. 0.72 in S. costus, which was totally absent in A. lappa and a band at $R_f$ 0.64 in A. lappa which was absent in S. costus Chlorogenic acid, used as a chemical marker for HPTLC analysis, was estimated to be 0.077% in S. costus as compared to 0.107% in A. lappa. Thus these detailed pharmacognostical parameters can be successfully used to distinguish between roots of S. costus and A. lappa.
