Introduction: Ochna integerrima (Lour.) Merr. belongs to family Ochnaceae, and it is a traditionally important herb in Southeast Asia. The objective of this study was to investigate the phytochemical compounds of various extracts from six samples. Methods: Thin Layer Chromatography (TLC) of the hexane, dichloromethane and 70\% ethanol extracts were performed for five important phytochemicals namely, alkaloids, flavonoids, terpene, cardiac glycosides and anthraquinone. Results: Terpene was found in all the samples that were extracted from all extracts, while cardiac glycosides and anthraquinone did not occur in all samples that were extracted from all extracts. Flavonoids were observed in all samples that were only extracted with dichloromethane, whereas it was found in some samples from the other extracts. The hexane extract compound was found in alkaloids in Garcinia cowa and Cryptolepis dubia, while the dichloromethane extract compound was discovered in Suregada multiflora, Capparis micracantha and Salacia chinensis. All samples extracted with 70\% methanol did not contain any alkaloid compounds. Terpene was found in the hexane extracted compounds. Conclusions: These findings suggested that Ochna integerrima (Lour.) Merr. is a potent source of medicinal phytochemical compounds that could lead to its use as medicinal products.

Vitex negundo Linn (verbenaceae), known as Nirgundi is important medicinal plant with variety of phytoconstituents having significant pharmacological activities. It has antiinflammatory, analgesic, anti-histaminic, anti-oxidant, anti-bacterial, hepatoprotective, antiimplantation, laxative, larvicidal, anti-arthritic, anticonvulsant and effective against snake venom activity. Two compounds namely vitexin and negundoside are reported to have anticancer and hepatoprotective activity respectively. For safe and effective use of herbal drugs in a formulation, proper standardization of herbal drugs is necessary. So, in this research paper basic pharmacognostic studies on Vitex negundo leaf extract like physicochemical parameters- ash values and extractive values, Fluorescence analysis, phytochemical screening, TLC profile with different solvent systems, behavior with different reagents and metal analysis was done. The findings throw light on preliminary standardization of this important medicinal plant. Key

Introduction: Orthosiphon stamineus has been widely used across Asian countries for the treatment of various diseases. The quality of herbal medicine determine its safety as well as efficacy; and geographical origin is important factor contributing on the quality of herb and its products. Materials and Methods: Thin Layer Chromatography (TLC) method combined with chemometric, Principal Component Analysis (PCA), has been employed to evaluate the quality of Orthosiphon stamineus leaves collected from eleven origins in Indonesia. Results: The results showed that mobile phase suitable for Orthosiphon stamineus was chloroform, dichloromethane, ethyl acetate (7:4:1). The method used has met the requirements of TLC system stability and precision. TLC-fingerprints analyzed with chemometrics showed an ability to discriminate Orthosiphon stamineus from various origins. PCA score plot of the first two principal components (PC) clearly distinguished 3 clusters of samples, whereas the loading plot of the first two PC showed that compounds with the Rf values of 0.0-0.1, 0.1-0.2, 0.2-0.3, and 0.9-1.0 are the most important compounds for clustering of samples. Conclusions: TLCfingerprint combined with the PCA was able to discriminate among the leaves of Orthosiphon stamineus originated from various locations. TLC-fingerprints analyzed with chemometrics can be used as an alternative of marker-oriented method to evaluate the quality of Orthosiphon stamineus.

Introduction: The extracts of the Pistacia species are known for their anti-inflammatory activity, including fruits and oil of P.\ atlantica. However, the inflammatory effect of the methanolic extract of P.\ atlantica leaves has not been studied. This work aimed at assessing the antiinflammatory and antioxidant activities of P.\ atlantica leaves extract in relation to phytochemical studies of flavonoids. Methods: The extract was obtained using sonication of leaves powder in 80 \% methanol. The analysis of phenolic compounds was carried out using thin-layer chromatography (TLC). The antioxidant activity was evaluated using DPPH, ABTS and FRAP assays. The anti-inflammatory activity was determined by the reduction of carrageenaninduced hind paw edema in mice. Results: The TLC revealed 3 glycosylated flavonoids and gallic acid derivatives. The flavonoids identified corresponded to rutin, quercetrin and other heterosides of quercetin, kaempferol and myricetin. Total phenolics and flavonoids contents were comparable for the male and female trees. The antioxidant activity did not show a significative difference between the two sexes, except for that evaluated by the FRAP assay which was significantly greater for the male tree leaves extract. The leaves extract permitted significative reduction of the edema at h3 and 6 in a dose-dependent manner (100 and 250 mg/kg), while diclofenac used as control reduced the edema at h 1.5. This difference could be explained by the pharmacokinetic and pharmacodynamic properties of diclofenac and P. atlantica leaves compounds. Conclusion: P. atlantica has a strong anti-inflammatory activity and constitutes a potential source for the development of new treatments.

Objective: Ageratum conyzoides Linn. (Asteraceae) has been widely used in African traditional medicine for healing mental and infectious diseases. The present study was designed to scientifically validate the traditional claim of A. conzyoides as anti-anxiety drug and to identify the compound responsible for the anxiolytic effects of A. conzyoides. Method: The methanol extract of A. conzyoides was prepared by soxhlet apparatus. The methanol extract was fractionated into ethylacetate and butanol fractions by liquid-liquid partitioning method. Methanol extract (100 and 200 mg/kg; p.o.) and its prepared fractions (25 and 50 mg/kg; p.o.) were evaluated for anxiolytic activity in mice by using elevated plus maze (EPM) model. Thin layer chromatography studies were performed to identify the possible anxiolytic component. Results: Methanol extract at both doses showed significant, when compared to vehicle control group, increase in time spent and number of entries in open arms of EPM confirming the anti-anxiety effects of A. conzyoides. Liquid-liquid partitioning of methanol extract gave two fractions (ethylacetate and butanol) which were administrated at 25 and 50 mg/kg doses to mice in EPM, respectively. Results showed that ethylacetate fraction was responsible for anxiolytic effects of methanol extract of A. conzyoides. The TLC studies were carried out for ethylacetate fraction and Quercetin was identified by comparing Rf values with the standard (Quercetin). Conclusion: The present investigation revealed that the extract has significant anxiolytic effect. The flavonoid quercetin may be responsible for the observed anxiolytic effects of A. conyzoides.
